5.1. Electrical connection

Danger to life due to electric shock! Switch off the power supply every time the clamp cover is opened! Make sure that the controller cannot be switched on! The kind of current (alternating current) and voltage have to correspond to the details on the con-

nection diagram. Connect controller according to the connection diagram.

DANGER

The configuration of the relays and sensors are shown in table “Configuration of relays and sensors” on page 14. Electrical connection via screw clips (single / fine wire, max. 1.5 mm²).The earth conductor of the mains supply is to be connected to the 5-pole clamp block ( ).The earths conductors of the consuming units (pumps, etc.) are to be connected to the 5-pole clamp block provided for that purpose. It must be ensured, that the earth conductor of the mains supply is connected to the same clamp block. Every clamp must have only one connection.A suitable strain relief has to be provided!Only Pt 1000-temperature sensors admitted for the controller have to be employed. All low voltage conducting leads (e.g. sensor leads) have to be laid separately to power supply voltage conducting leads.The polarity of the sensor leads (max. length of lead 100 m) need not be observed!

Attention!Only safety extra low voltage is allowed to be connected with the low voltage relays (NVR). With the relays on the high voltage side (R1-R5) no safety extra low voltage is allowed to be connected. !

Mount the clamp cover again after the electrical connection has been finished.

5.2. Mounting of the sensors

Mounting of the outside temperature sensor:The outside temperature sensor should be mounted at least 2 meters above the ground. There must be no in-fluence by chimneys, windows or drip rails. The outside temperature sensor should be mounted on the north or the northeast side of the house and should not be exposed to direct sunlight.In the case of larger installations with separate heating circuits, outside temperature sensors are allocated to the outside walls.

Mounting of the flow sensor:The flow sensor is mounted behind the heating system pump on the heating flow using a pipe clamp. The in-stallation site must be clean and provided with a heat-conductive paste.

Mounting of the boiler temperature sensor:The boiler temperature sensor is mounted in the same immersion sleeve, in which the boiler thermostat sensor is located.

Mounting of the hot water storage sensor:The hot water storage sensor is mounted in the immersion pipe of the hot water storage tank.

9. Protection functions9.1. Blocking protection of the pump

The pumps are switched on every day at 12 o´clock for 10 seconds to avoid a blocking of the pumps.

9.2. Blocking protection of the mixerWhen the heating controller switches from day level to night level automatically, the heating circuit mixer is first moved to position OPEN and is after that moved to position CLOSED. This is done to avoid a blocking of the heating circuit mixer. While this movement the corresponding heating circuit pump is switched off. After that the heating circuit mixer is moved in the position that is adjusted in the heating controller.

10. Errors and troubleshootingPlease check the following points, if your heating controller do not operate successfully:

1. Current supply:The current supply works, if a display appears, e.g. the starting display. Check the power supply voltage and the controller fuse, if there is no display.

2. Automatic sensor monitoring via the heating controller: All used sensors are checked on short circuit and disconnection. If an error occurs, the display shows the sensor number and the value “H °C“ or “L °C“. The controller auto-

matically changes to manual operating mode, if E3-6/5 = YES. Only one error is displayed at one time. More errors are displayed one after the other in numerical order.

3. Sensors and sensor leads:When the display (normal display and information level) shows meaningful temperatures, all is well. In case of sensor interruption, the display shows “H °C“ and in case of a sensor short-circuit the display shows “L °C“. If the temperatures shown are not meaningful, you can check the values of resistance from the following chart, using a resistance measurement device:

Resistance chart Pt 1000-temperature sensor-20 °C 922 ohm 20 °C 1078 ohm 60 °C 1232 ohm 100 °C 1385 ohm-10 °C 961 ohm 30 °C 1117 ohm 70 °C 1271 ohm 110 °C 1423 ohm

0 °C 1000 ohm 40 °C 1155 ohm 80 °C 1309 ohm 120 °C 1461 ohm10 °C 1039 ohm 50 °C 1194 ohm 90 °C 1347 ohm 130 °C 1498 ohm

4. Switching outputs:Check the relay switching outlets via the submenu relay test, if the heating controller does not switch on the corresponding consumer devices (burner, pumps and valves).

Replace the heating controller, if the error still exists after checking the above mentioned points.

Danger to life due to electric shock! Only trained, competent and authorised persons (electrical technician according to DIN VDE

1000-10 and BGV A3) are allowed to do mounting, electrical installation and commissioning, maintenance and repair work on the heating controller!

Follow all local regulations of the responsible energy service providers! Ensure that the power supply is switched off and that the controller cannot be switched on before

starting installation or repair work on electrical equipment. Never work on current conducting parts!
