1. INTRODUCTION

The comfort of radiant heating is not a modern invention. In the beginning floor has been used for this purpose, but with the development of the heating systems wall and ceiling also appeared as an adequate surface. Radopress Watt offers solution for these surface heating types – underfloor heating, wall heating-cooling and ceiling heating-cooling.

Advantages of surface heating

The energy released through radiation generates a pleasant temperature sensation. In order to reach the same comfort sensation as the temperature sensation caused by traditional heating methods a room temperature of even 2-3°C lower is enough in the case of surface heating. As a 1°C lower temperature means approximately 6% saving of the heating costs, so surface heating not only improves the temperature sensation but also spares our wallets.The low supply medium temperature can be generated through heat pump or condensation boiler as well (the efficiency of these is bigger by lower supply temperature).

The less energy input – not to neglect – means a smaller environment load as well, which is a very important point of view nowadays.

The favorable effect of surface heating types on physiology is to be mentioned, too. By surface heating there is no dust stirred by the weak air flow generated through the convection of the radiator heating, and the air is not so “dry” either, because the air temperature being 2-3 grades lower is accompanied by a favorable (higher) relative humidity.

In the case of such a heating type the radiators also do not take away from the space either (although, the wardrobes and other furniture objects have to be considered during planning of the surface heating as well).

To sum up, the definite advantages of surface heating are the following:

• pleasant temperature sensation• efficient operation• preserves the environment• favorable effect on physiology

2. SCOPE OF APPLICATION 2.1. UNDERFLOOR HEATING

By underfloor heating the warm water flowing through the heating pipelines laid into the floor heats the structure of the floor, which releases the heat in the room evenly. Underfloor heating can be applied either in itself or together, combined with other surface heating types (e.g. wall heating, ceiling heating). As the heating, respectively the cooling of the floor structure (concrete) takes a relatively long time, the system has great temperature inertia. That is why underfloor heating, combined with other surface heating types, is to be used as tempering heating. Now underfloor heating ensures a permanent heat import and pleasant, mild floor temperature, while the wall or ceiling heating covers the rest of the needed heat performance, and takes care of regulating the temperature relatively quickly and according to the demand (the heat inertia of the 2-3 cm thick plaster is small). In this case we talk about floor tempering, as the increased heating surface always results in lower supply water temperature, as well as floor temperature, eliminating the flutter of dust caused by underfloor heating.For the sake of healthcare the surface temperature of underfloor heating can be max. 29°C in the living zone (in the bathroom 33°C), and 35°C in the border zone (50 cm along the wall).

By the measuring the surface covered by furniture is subtracted from the available floor surface, or a 15-20% smaller surface is to be calculated with. For the layers applied by underfloor heating see Figure 7.

Advantages of underfloor heating: • better temperature sensation• heat energy saving (lower heating water average temperature)• even surface temperature distribution• flexible positioning of furniture and other contents

2.1.1. Elements of the underfloor heating system

Underfloor heating pipes

Two types of pipes can be used for the RADOPRESS underfloor heating system. One of them is a PEX/AL/PEX and PE-RT/AL/PE-RT (with aluminum layer) pipe of five layers and of type “M”, which is applicable to the usage in underfloor heating systems because of its flexibility, form-fitness and the oxygen tightness due to the aluminum layer. The other is a pipe of PE-RT (Figure 1). This pipe is of type “P”, and of more layers (it has five layers as well), where the pressure pipe is PE-RT (polyethylene with raised temperature resistance), combined with a plastic layer of EVOH (ethyl-vinyl-alcohol), protecting against oxygen, too. The closing layer made of EVOH significantly decreases the oxygen diffusion through the walls of the inner pipe, hindering effectively the oxidation processes in the heating circuit – so corrosion of the boiler or the radiators can be avoided. The EVOH layer is surrounded by a layer of the same material that of the inner pipe, which protects it from external damage. The continuous contact between the layers is provided by a layer of glue. The PERT underfloor heating pipes have to be tempered below 10°C before laying, and they are not allowed to be laid below 5°C.

Underfloor heating insulation

The RADOPRESS (FT-ROLLE+) insulation is an EPST polystyrene floor insulation, slit into sections for better handling, 3 cm thick, with fiber glass reinforced heat mirror film on it (Figure 2). The lamella has a raster net of 5 cm, which allows the simple cut of the coil, respectively the simple and quick laying of the heating pipes. It is recommended to make a prior planning of the installation. The RADOPRESS insulation has a self-adhesive border of about 4 cm wide, so they can be easily fixed to each other. The insulation lamella with a capacity of 3,5 kN/m2 is sectioned for easier handling (in coils of 1m x 10 m).

Expansion insulation strip

It serves for absorption of thermal expansion of concrete along the wall, as well as for the inner dilatation of the surface. Its material is not absorbent, expanded polyethylene. Thickness 10 m, coil length 25 m. In the lower section of 30 mm of the total 130 mm high border strip there is a notch to make the placing easier (Figure 5).

Tools and fixing materials

The underfloor heating pipe has to be fixed on the insulation with a fixing clip (Figure 4). A stapler gun is used for effort free work, quicker installation, eliminating need of bending (Figure 3). The quantity and position of the clips are to be chosen according to demand. By a linear pipe section the fixing clip has to be fastened every half-one meter, double at the beginning and at the end of the bends. Due to the fiber glass reinforced material pulling out the clips in a non-destructive way is not possible.

Manifold

The underfloor heating manifold with 2-12 circuits is provided completely mounted and ready for use (Figures 6/a., 6/b.).

Every 1’’ manifold body has ¾ euro conic connections for circuits, and threaded on both ends. The underfloor heating manifold is sold completely mounted, ready for use.

This type contains the flow meters placed on supply side, which helps regulating the flow and comes with shut off valves embedded into flow meters with a revolutionary new solution. The combined regulating valve-closing armatures are to be found on the return side. The package also contains 1” ball valves as main shut off valves (2 ball valves) and the filling-draining-aerating end piece that can be mounted to the other end of the manifold. These are all mounted to the relevant bracket, facilitating immediate use.

The distance of the circuit connections is 55 mm. The M30x1,5 thread on the top of the regulating valve allows after the removal of the shut-off-cap the easy assembly of the thermo-electric actuator (not included in the package). Each manifold is made of best quality copper alloy, and leaves the factory after a pressure test.

2.1.2. Construction of the system

Floor insulation

It is recommended to apply a polystyrene layer of 4-5 cm thickness for floor insulation above heated rooms, and 8-10 cm above not heated rooms.

Expansion clearances:

• use expansion insulation strips for compensating thermal expansion of the floor (generated always on the circumference of the floor)• a significant thermal expansion in the heating zones is

generated in the following cases: - area of the zone is greater than 40 m² - relation of zone length and width is greater than 2 - zone length is more than 8 m - the zone goes through openings (e.g. door)• The harmful impacts of thermal expansion can be avoided

by constructing expansion zones. Where underfloor heating pipe cross dilatation, protection pipes have to be used in both directions, in length of 10-10 cm (Figure 8).

Layout of the heating circuit:

• layout in spiral form – equal heat division on the complete heating surface (Figure 9)• layout in serpentine form – unequal heat division – not

recommended (Figure 9)• layout in spiral form with border zone – if higher temperature

is needed in border zone (e.g. by outer walls) (Figure 9)• applying smaller spacing along the wall to reach higher

temperatures (than by border zone)• It is desirable to have a maximum pipe length of 100 m per

circuit, but in no case should it exceed 120 m.

Concrete floor with fluxing additives

The concrete floor above the pipe should be at least 5 cm thick. It is recommended to apply a cement smoothing layer – recommended cement content is 300-350 kg/m3, water/concrete ratio is 0,45; particle dimension of gravel: less than 8 mm. In order to improve the plasticity and thermo-technical features, fluxing additive to the concrete mixture is advisable. By preparing the concrete mixture the system has to be filled up with water, and kept under 0,3 MPa (3 bar) pressure.

Pressure test and concrete work

The pressure test of the underfloor heating has to be accomplished before placing the concrete on the pipes, with a pressure of 6 bar, 24 hours long. Leave the concrete to fasten and dry under natural circumstances (3-4 weeks), then start the first heating with 25°C of water temperature. Keep this temperature up for 3 days, and then increase it daily with 5°C, until the biggest working temperature is reached.

Connection to the manifold

The end of each manifold has an outer thread of 1’’, where the ball valves and the filling-draining-aerating valves are connected. These are industrial armatures and can be mounted with the flat sealing attached to the sleeve nuts. We can only guarantee failure-free work in case of using such armatures.

Connection with pipes

1. Cut the underfloor heating pipe perpendicularly, cut the burrs and calibrate it. Pull the sleeve nut onto the pipe.2. Pull the clamp ring onto the pipe, and stick the conical connector into the pipe.3. Push the mounted pipe end into the connector with thread.4. Screw the sleeve nut onto it manually. Push the pipe in until the block.5. Hold against it with a 24 mm open-end wrench by the connection collar, and fasten the sleeve nut with a 30 mm open-

end wrench (with a torque of approximately 25-30Nm).

2.1.3. Installation

Mount the expansion insulation strips along the walls (they are in “L” form breakable and can be put on the base). After that place the insulations, fixing them to each other, crashed to the border zone and put on their “bottoms” (Figure 5/b.). Laying the pipes is possible in two layouts: serpentine (snake line) or spiral (because of equal surface temperature the spiral layout is recommended).Fasten the fixing clips on the straight sections every half-one meter, by the curves – at their beginnings and ends – double (tightly next to each other).

The pipes crossing the dilatation should be lead through the expansion clearance in a protection pipe so the length of the protection pipe is at least 10 cm on both sides (Figure 8). For the set-up on the manifold bend supports should be used (Figure 10).The pipes are connected to the flow metered manifold with eurocone connector.By keeping the rules of the pressure test and concreting under pressure, there has to be at least 5 cm concrete covering the pipes, counting from their upper edges.

Washing through and filling the heating circuits:

For the filling and washing through connect a hose to the ½’’ or ¾’’ thread of the filling cock. Open / close the filling cock with the help of the arm or the square axis. Each and every circuit has to be rinsed separately. Avoid too great a pressure, by keeping the draining cock open. The manifold can only be used with water.

Close the ball valves in the main circuit. Close all the regulating valves with the help of the protection caps. Connect the hose to the filling and draining cock. The draining tap of the return circuit should be open! All the flow meters should be completely open! Close the regulating l valves of the circuits in the return line, and leave only the one completely open that you wish to rinse! Rinse each one of the circuits separately with clear water. Dismount the hoses from the cocks after the filling and rinsing.

The heating circuits can be marked easily with the stickers attached to the manifold. This can ensure that the circuits of the relevant rooms will be connected to the relevant place on the manifold. The manifold has undergone a pressure test in the producing factory, and its function is controlled. The value of the test pressure is 6 bar. Shifting of the valve axis is 11,8 mm.

Adjusting the flow

The aim is to let heating water of the planned quantity (l/min) into each underfloor heating circuit. This is typically differ-ent for each circuit.

1. Screw off the plastic cap, and close the regulating valve rotating it to the right with the help of an adjusting wrench (closed = smallest quantity).

2. Adjust the wished flow with rotating the adjusting wrench to the left. Read the displayed value from the flow meter. After setting every circuit, check the values and adjust them, if still needed.

3. After the setting turn back the protection cap or mount the actuator in order to protect the valves from contamination or unintended misadjusting.

4. The thick thread on the setting spindle of the regulating valve should not be visible after the upper plane of the hexa-hedral part of 19. As compared to the completely closed position, the valve is in a completely open position after 2,5-3 left turns.

5. The return regulating valves can be closed, e.g. for the sake of filling and rinsing the circuits. Here the plastic cap has to be rotated clockwise for closing. The flow meters can be closed with the help of the adjusting wrench. These meters are not capable of regulating.

For the permanent closure of a circuit always use a blind cap with ¾’’ thread and sealing.

By using an actuator, the adjusting spindle should be open for a 0,5-1 turn, independent from the adjustable flow. This way the room temperature will be set by the actuator.

2.1.4. IsoTherm mixing unit

For thermostatic regulating underfloor heating with low temperature

Advantages:

• Compact unit, ready for use• The supply circuit can be adjusted between 30-50°C• The temperature of the supplying water can be read directly from the built-in thermometer• There is a heat limiter protecting against too high supply temperature• Factory mounted mixing valve and heat limiter• Simple connection with sleeve nuts•Can be connected both on the right and the left hand side of the manifold•Can be used up to 10kW heat output

Application

The IsoTherm can be used for keeping supply water temperature of surface heaters in low temperature heating systems on a permanent level and value. The supply temperature can be set between 30-50°C. It is also suitable for keeping supply temperature low in a high temperature heating systems (e.g. radiators) on a permanent level and value, thus separating the two heating methods. Due to convenience and sanitary considerations the surface temperature of the floor in the living zone cannot be higher than 29°C, and in the border zone 35°C.

ADJUSTMENT OF THE UNDERFLOOR FLOW TEMPERATURE

In the event of maximum heat output demanded (rated output), the boiler flow temperature must be at least 15°C higher than the desired flow temperature in the underfloor circuit!

The flow temperature is factory-made set to the values mentioned above. The top of the pilot pin meets the face of the adjusting hand wheel (see Figure 11) By turning the adjusting hand wheel in minus or plus direction the set flow temperature is changed accordingly. The hand wheel clicks with the rotation. Each “click” means a set temperature change of the desired value around 1 °C.

Decrease of the desired flow temperature: Turning the adjusting hand wheel in the clockwise direction. If the pilot pin moves out from the adjusting hand wheel, this entails a lower target temperature (see Figure 12). Each “click” in the clockwise direction reduces the target temperature around 1 °C. The set range of temperature is from 30°C to 50 or 45 °C to 60 according to the type used. However, the adjusting hand wheel can be moved further up and down. Outside of the temperature range, this causes only small changes in the target temperature.

Increase of the desired flow temperature: Turning the adjusting hand wheel in the anti-clockwise direction. If the pilot pin moves into the hand wheel, this entails a higher target temperature (see Figure 13). Each “click” in the anti clockwise direction rises the target temperature around 1°C.

11. Figure 12. Figure 13. Figure

Design / Mode of operation

The IsoTherm low-temperature control unit is made up of precision-matched components with flat-seal connections. The target value for the supply flow temperature set on the TempGuard thermostatic mixing valve is continuously monitored by a sensor positioned directly in the flow. The mixing valve feeds a greater or less volume of hot water from the boiler circuit to the heating circuit manifold to balance out temperature deviations more or less instantly.

The “injected” hot water is directly mixed with the water coming from the return flow collector of the manifold and makes its way via the circulation pump and the supply flow manifold to the connected heating circuits. A high temperature limiter also installed in the supply flow branch switches the pump off immediately if the maximum temperature (e.g. 80°C) is exceeded. The bypass ensures a certain degree of continuous circulation that:

a.) passes on the actual supply flow temperature to the mixer valve on an ongoing basis.b.) permits dissipation of differential pressure with closed heating circuits and continued operation of the pump (e.g. via

pump logic) through the integrated overpressure shutoff.

Installation

The IsoTherm can be mounted either to the right or left on all heating circuit manifolds with 1” thread. All components are fitted with flat-seal screw connections. Using suitable accessories, the control unit can also be equipped with heat meters.Maximum comfort with minimum use of energy is achieved by installing an actuator on each regulating valve of the return manifold. This permits regulation of individual room temperatures as desired from the user.

2.2. WALL- AND CEILING HEATING

Advantages of wall- and ceiling heating

By wall heating the surface is heated with pipes built-in under the plaster, which transmits the energy with radiation to the environment. Wall heating can be applied individually as well, but in rooms with cold floor it can be combined with underfloor heating too, increasing the comfort this way. In this case it is called floor tempering, as the increased heating surface always results in lower heating water, respectively floor temperature, eliminating dust fluttering caused by individual underfloor heating. The same applies to ceiling heating as well, because the combined application of the heating systems further increases the sense of comfort. The lower temperature of the room has a positive impact on the sympathetic nervous system, our general condition improves, we feel fresher, and the psychical potential of our brains increases as well. From a medical point of view it is remarkable that the dust load of rooms significantly decreases by wall heating because of the lower convection.In the first place it is recommended to construct wall heating on the inner surface of the outer walls of the room, and only in the second place on the inner walls, as the cold (or heat in the summer) radiation comes from this direction.

Wall- and ceiling cooling

Wall heating system also can be used for cooling in the summer. Cooling requires more surface than heating, therefore the system used for cooling as well will be over dimensioned in heating operating mode. This can be an advantage at the same time, because heating water of lower temperature is needed. The extra surface because of cooling can be mounted on the ceiling as well – as it is radiant heating - , it will function correctly. As every radiant heating, wall- and ceiling heating have a convection element as well. In the case of the ceiling it is especially advantageous in cooling operating mode as cool air strives downwards by its nature, exactly where it is needed.By surface cooling special attention has to be made to avoid condensation of moist. If you wish not only to heat but also to cool, the regulating system has to be made capable of avoiding the damp condensing on the surfaces. A more sophisticated regulating system is needed for that - than for heating. Solutions will be drawn up in a later chapter.

2.2.1. Elements of wall- and ceiling heating

The system elements of wall- and ceiling heating and their mounting is the same, so they are handled and described together.

These are the following:

• 10x1,3 mm, five layer PE-RT-EVOH (ethyl-vinyl-alcohol)-PE-RT pipe (Figure a.)• 20x2 mm Pex-Al-Pex or PE-RT-AL-PE-RT pipe for distribution line (Figure b.)•Mounting rail with 25 mm spacing (Figure c.)• 6X60mm screw (for fixing rail to brick, concrete or YTONG.• Press fittings with TH contour for the connection between distribution line and 10 mm pipes (Figure d.)•Manifold with flow meter (Figure e.)•Regulating system for heating and cooling solutions

2.2.2. Construction of the system

The circuits mounted on the wall/ceiling in serpentine are called field or register, and the pipes coming from the manifold, filling the circuits, are called distributor pipes. The heating fields are constructed from 10 mm pipes. The serpentine (snake line) laying mode can be implemented both vertically and horizontally, depending on the available space. It is recommended to use the solution with less pipe turns (Figure 14).

The heating field constructed from 40 m pipe (coil length of 120 and 240 is adapted to that) is connected in Tichelman-system (Figure 15) to the distributor line. Of course another circuit length different from this can be used as well, the main thing is, circuits of the same lengths have to be constructed. If it is necessary to use different length from the others, the difference should not exceed 10%. Many shorter circuits can be connected in a series too, so there is the same pipe length generated as in the other circuits.

Max. 120 m of register can be connected to one manifold connection (or to one distributor line) with max. 40 m per reg-ister.The most often used spacing is 10 cm, but the pipe and the fixing rail are capable for constructing different spacing as well, e.g. 7,5 cm. In case of a pipe with 40 m length and 10 cm spacing the coverable surface is 4 m2, while with a spacing of 7,5 cm it is 3 m2. No matter how much spacing you choose, the bending radius of the pipe should not be smaller than 5D, i.e. 50 mm.

14. Figure

15. Figure

13

If the pipe is mounted with spacing smaller than 10 cm, the pipe bend has to be expanded by the turns as sponge fingers in order to have the adequate bending radius (Figure 16).

For the last field counted from the floor use a 10 mm bend support for easy installation of the pipe bend, bending upward to the wall (Figure 17/a.).

In order to have an adequately tight piping, not inclined to bend out- or inward from the wall, the rails have to be placed in a distance of 350-450 mm from each other (Figure 18). The pipe has to be fixed by the turns too, using a short piece of rail (Figure 17/b.).

18. Figure

17/a. Figure

16. Figure

17/b. Figure

14

The plaster should serve the purpose, so it can not be at all either heat-insulating or light plaster. The thickness of the plaster should be at least 10 mm above the pipe, which has to be protected with a glass net in order to avoid cracks, in a way that the net does not touch the pipes, but be placed embedded into the covering layer (Figure 19).The glass net should exceed the edges of the field at least with 25 cm around. The neighboring glass nets should be made with an overlapping of at least 10 cm.

The 20x2 mm distributor lines and the fittings serving the fields have to be heat insulated (at least 13 mm thick).

The volumetric current can be adjusted per circuit on the manifold between 0-4 liter / minute. The bubbles stuck in the pipes after filling and de-aerating and drifting continuously with the water flow, can be easily and effectively removed with a micro-bubble separator, built-in to the supply line of the primary circuit, before the manifold supply side, as close to the boiler as possible.

2.2.3. Installation

As a first step mark the meter line counted from the final level of the floor to the wall. This helps in the correct measuring of the lower and upper lines of the field.

The electric cables are running under the pipes mounted on the wall, respectively on the ceiling, sunken into the wall. Make sure that every electric cabling is ready, and they are running in a protection pipe. The low temperatures used by surface heating systems will not harm the insulation of the electric cables otherwise getting warm.

The fixing rails can be fastened on a brick wall quickly and easily with a so-called brick screw without wall plug, where after drilling a hole of 4 mm a screw of 6 mm has to be driven in. It is recommended to use a hitting nail or hitting wall plug (fast fixing with only one hammer hit). Without this a screw of 6 mm being driven into a hole of 5 mm results also in an acceptable solution.

For lack of a cutting tool the Radopress Watt rails can be broken into pieces manually as well, along the pre-scored break lines (Figure 20).

The framing dimensions of the field to be constructed from a 40 m long pipe can be calculated the following way: besides the spacing also the pipe demand of the pipe turns (Figure 16) and the two sections linked to the distributor line (supply, return) have to be taken into account as well. Generally speaking the 40 m pipe mounted with spacing of 10 cm covers 4 m2, and with spacing of 7,5 cm an area of 3 m2.

If the wall part available or uncovered by the window is not enough for a total circuit of 40 m, many smaller fields can be prepared as well.

If the circuit of planned length should not be enough exactly to the distributor line, the method seen in the picture below can also be chosen (Figure 21).

When the circuits covering the smaller wall part are connected within a field (connected in a series), take care of the following: the length of the fields branching off the same distributor line has to have almost the same length (rule of 10%).It is practical to construct the turns of the pipes going from the wall to the ceiling in a way that the bending radius of the pipes does not hinder the construction of the adequate plaster in the corner (Figure 22).

22. Figure

21. Figure

Mount the manifold(the version with flow meter, described in underfloor heating section). Route of distributor line depends on their positioning in the flat.

By laying the pipes first all the fields should be constructed, and then the distributor pipes.In case of installing 10 mm pipe in cold weather, coils to be used should be tempered above 5°C. Do not lay pipes under 0°C!At the end cut, remove burrs, calibrate the pipes, place the fittings and press the connections.

For heat insulation preferably choose closed cell material (regulationprevents condensation in any case), but the insulation with closed cells does not absorb damp even in case of condensation, so preserving its feature of heat insulation.Wrap the fittings with self-adhesive heat insulation strips on the whole surface. Above the heat insulation this also gives the fitting a mechanical protection needed by placing the concrete.

Filling the system with water and de-aeration is to be accomplished one by one, from circuit to circuit (see Chapter 2.1.3).Test pressure should be double the working pressure, but at least 5 bars. After 24 hours, the pressure loss cannot be more than 0,2 bar, otherwise the leak has to be searched for.

After doing the pressure test take back the pressure to the operating pressure, and leave it there, because plastering must be done under pressure. This helps realizing if any pipe damage occurs. This way pipes take their final position (they fit), reaching their working dimension, since they extend little bit due to pressure inside.

Generally speaking, regulation of heating is easier and cheaper than cooling, where sensor(s) permanently watching relative humidity, integrated into a regulating system capable of that.In the next sections the regulating solutions offered by Radopress Watt are described.

3.1. ELEMENTS OF THE REGULATING SYSTEM

All heating systems must have proper and correct regulation to maintain and achieve comfortable living conditions, energy efficient operation and comply with current building regulations. To get the best results from your under underfloor heating system Pipelife recommends individual regulation in each room. A room thermostat regulates s the actuators that open or close the pipe circuits specific to that area. The room thermostat system also takes into account all other heat sources including sunshine body temperature. There are various types of regulations available from boiler controls through air temperature regulation to wireless regulation. Some regulations offer various additions such as night setback mode, separate time and temperature controlled thermostats (i.e. programmable), tamper-proof thermostats. Centralized wiring units are also included to provide the complete system regulation to include boilers radiators and domestic water.

Central controller (DDC)

The central controller is a freely programmable, intelligent regulating system, based on a bus system (elements are in serial connection; see Page 26), which regulates heating and cooling system according to the measured and set parameters.Although the system has been developed especially for regulating heating-cooling systems with a possibility of adjusting the temperature in all rooms independently along with dew point calculation, nevertheless it can be fit to every HVAC solution, as it is freely programmable. User can monitor, and adjust system via the Internet.

The central unit consists of the following:

12 digital outputs for pumps of the heating or cooling circuit, shifting valves for the winter-summer shift, electrothermic actuators - operating the heating or cooling circuits -, controls the mixing valve, boiler, chiller, drier and heat pump switch on-off. The number of the digital outputs of the control unit can be extended with extender modules (up to 128 outputs).4 temperature sensor inputs, which are capable of measuring the temperature needed for operation (external, supply water, buffer tank…).4 digital inputs receiving voltage-free contact (night current monitoring, sensor for window opening, monitoring of being at home from an alarm system…).A central unit is capable of controlling maximum 3 mixing valves with 3-point controlled actuator. As the whole DDC-system is based on bus communication, more control units can be built in the system as well, so any regulation task can be handled.

Controller extender module

If the 12-relay-output on the central controller is not enough, there is a possibility to build in an extender module with a 12-relay-output. Any number of digital extender modules can be built in into the system. It is connected to the bus, as all the other modules of the system (see Page 26.).

20

Wall control unit

Here the user gets the chance to adjust the system according to his/her needs with the help of a menu system which can be used easily. Through the wall control unit the current parameters of all the rooms can be recalled, and all the required adjustments can be implemented (prog-ram, etc.). The unit itself works as a combined sensor (i.e. measures the temperature and the relative humidity). For detailed information on the tasks accomplishable with the wall control units please check the manual of the wall control units.It is sold in designs with push buttons and touch screen.

Combined sensor

Combined sensor is a no display wall unit measures relative humidity and temperature. It is situated right next to light switch placed behind a switch blind cover identical in look with the switch itself . Combined sensor’s parameters can be read and set through wall control unit.Its housing sunken into the wall with a 4 mm hole drilled on the middle of cover facilitating sensor to have connection to room air. The sensor has to be fastened to the inner side of the box with an adhesive thermo insulation piece included in the package.

Internet module

3.2. REGULATING UNDERFLOOR HEATING

3.2.1. Underfloor heating as an independent heating (23. Figure)

For regulating rooms independently choose any of the thermostats listed in the catalogue. Thermostats send signal to connecting box placed near manifold, which transmits it to the thermoelectric actuators. These open and close valves belong to the heating circuits. So the circuits open or close independently from each other according to the heating demand based on the signals coming in from the thermostats in the single rooms.If there is one actuator opened, connection box switches the boiler and the circulating pump on and off.

If you wish to control the function of a single room according to a program, choose room thermostats capable of this, or a timer with connection box, where every room parameter can be adjusted. In case of using timer there is no need for “smart” room thermostats. Should you apply thermostats functioning according to a program, timer’s (attached to connecting box) will overwrite it, i.e. the control function will take place according to the program set in the timer.The use of timer allows of course a number of other system parameter adjustments optimizing heating system’s operation.

Besides the facts described previously, hydraulic system includes a mixing unit (FT-FWR/N), that keeps constant underfloor heating supply water temperature regardless primary water temperature from boiler. The mixing unit is simply connected to the manifold with a sleeve nut and contains the circulating pump and the temperature limiter. For a detailed function description see Chapter 2.1.4.(Since primary (boiler circuit) and the mixed (underfloor heating) circuit is not separated hydraulically, there is no need for expansion vessel in the underfloor heating circuit.)In the following schematic drawings a wired regulating system is shown in Figure 23 while a wireless one in Figure 24). (Next to the regulating elements the product codes can be seen necessary for the solution. Different room thermostats represent different choices for particular room thermostats.)

3.2.2. Underfloor heating combined with radiator heating

In mixed heating system, radiators with smaller heat inertia make underfloor heating more flexible, especially in transition periods when satisfying regulation is difficult. (If it is still cold at night, but warm during the day, overheating can happen.)Due to the facts mentioned above, for those who choose mixed heating method it is recommended to cover 30-40% of the heat demand with radiator heating.

The regulation does not differ from previously mentioned ones. If the heat source (boiler) produces water of high temperature necessary for the radiators, then the temperature step is bigger between the primary and secondary (mixed) circuits.Note: The radiators can be fed also by a supply line of low temperature, but in this case ones with bigger dimensions have to be chosen (according to calculation).In the following schematic drawings a wired regulating system is shown in Figure 25, while a wireless one in Figure 26).

3.3. REGULATION OF WALL- AND CEILING HEATING-COOLING

Radopress Watt offers three different regulating solutions for surface cooling, with different comfort and complexity grades. The choice between these is in first grade a financial and no technical question.

• supply circuit with permanent temperature, pump switching on and off (e.g. passive heating*),•regulation with dew point monitoring, controlled for one room,• regulation with dew point monitoring, controlled per room.

3.3.1. Supply circuit with permanent temperature, pump switching on and off

This kind of cooling regulation that goes with compromises can be applied typically for e.g. passive cooling.There is no relative humidity monitoring. To avoid moisture condensing a safely high value of supply water temperature has to be adjusted (with heat exchanger). A supply temperature higher than the ideal value (set for possible highest humidity) makes only a cooling performance utilization possible that is slightly more unfavorable than the optimal one.It can be built from system elements without cables (with radio frequency)(Figure 27).

* By passive cooling the ground water pumped out from one of the wells will be pushed back through a heat exchanger (into the ground) into another well, and so the flat is cooled with it, i.e. no extra energy is used for cooling the liquid.

3.3.2. Regulation with dew point monitoring, controlled for one room

A solution that needs some compromises.The system generates the supply water temperature above the dew point from the dew point value calculated from the measuring values of the contact thermometer assembled on the supply pipe and that of the room thermostat with relative humidity sensor, placed in the chosen “reference room”.

The cooling performance of all the rooms depends on the air status of the main room. As a “reference room” you can choose the living room (not the bathroom – that is not necessarily cooled, and not the kitchen, where the exhauster takes away the steam), where most of the people are, and with breathing out extra steam gets into the air. It can be built from system elements without cable (with radio frequency)(Figure 28).

3.3.3. Regulation with dew point monitoring, controlled per room

Regulating without compromises, resulting in full comfort and cooling performance (Figure 29).There is a combined temperature-relative humidity sensor without display in every room but one. The wall control unit (with digital display or touch screen) is positioned in a chosen room (or by levels in case of more levels), with the help of which communication with all the system elements is possible. The parameters of the rooms can be recalled and adjusted (e.g. the values of temperature and relative humidity measured by the combined sensors, the required temperature of any room, etc.), and you can choose programs per room.Parallel to the increase of the humidity the regulating system – with evaluating the data for all the rooms at the same time – increases by demand the supply water temperature in order to maintain the permanent cooling. (The systems of other producers, by supply water of constant medium temperature, and by increased humidity simply shut off the cooling circuit, switching off cooling completely).In the case of extreme heat and humidity, when the increase of cooling water does not go together with considerable cooling performance, it closes the given room out of the cooling.An internet module can also be chosen for the system, for realizing remote communication, respectively regulation can be connected to the alarm system of the flat, too. (In the alarmed, i.e. not used zones the heating or cooling performance is decreased individually.)The system elements function with 12V low voltage, in a bus system, are connected in a series, and have – in relation to the solution with star-points – only small demand for cabeling work.
