The N-Comfort thermostat programme adds a new and powerful dimension to Nexans’ heating system portfolio.

Precise and accurate temperature control is important to fully achieve the advan-tages of floor heating without using more electric energy than necessary. Heating cables in combination with an accurate thermostat are probably the most energy efficient heating system one can have in a modern building.

The design of the thermostat is unique, and every detail has been carefully designed paying special attention to aesthetic appear ance, user-friendliness and quality, as required and demanded by both consumers and professional installers.

In addition to the thermostats being easy to install and adjust, the temperature is digitally controlled by software specifically developed for underfloor heating systems.The N-Comfort series comprises four different controllers – three thermostats and one power regulator. Whatever your need is, you will find a N-Comfort controller optimal for your needs. From just simple power control to advanced day/night control, N-Comfort will do the job!

N-Comfort CDFR-001 and CDFR-002The N-Comfort CDFR range comprises programmable digital thermostats for use in all indoor room types. The two versions are delivered with different factory set-ups to make installation as quick and easy as possible, but both types can be programmed to fit the users’ needs in any room. The thermo-stats are equipped with both room and floor sensor. It is up to the installer to determine which sensor to activate. If necessary, both sensors can be acti-vated. The floor sensor will then function as a temperature limitation sensor in order to avoid overheating of the floor.

N-Comfort CEF-001The model CEF-001 is an electronic thermostat for use in all indoor room types. It is equipped with both a room and a floor sensor. Which sensor to use can be chosen by simply adjusting a jumper behind the front cover. If the floor sensor is the active sensor, it will also function as a temperature limitation sensor. The maxi-mum allowed floor temperature can be set by adjusting a potentiometer positioned behind the front cover.

The N-Comfort CEF-001 is recommended for use in all room types. It is especially suitable for bathrooms and other rooms with concrete floors and high output (100 – 150 W/m²).

N-Comfort CR-001CR-001 is a power regulator with no sensor. By turning the wheel, the user can control the heating cable’s output. The regulator works with a cycle of 30 minutes. Turning the wheel tells the regulator how many minutes it shall stay on and off within the cycle.

Example: The regulator wheel is put in position ”5”, pointing straight upwards. The regulator will turn the cables on for 15 minutes and off for 15 minutes, working in 30 minute cycles. The resulting heating cable output is 50% of the nominal wattage.

The N-Comfort CR-001 is recommended for use in small rooms with concrete floors like for example toilets, small bathrooms etc. It is also ideal for replacing old 1-2-3-switches commonly used in the 70’s and 80’s.

Installation of floor sensorApplicable for: CDFR-001, CDFR-002,

CEF-001Parts needed: Sensor (enclosed in

thermostat package) Flexible conduit, same

length as the sensor Piece of tape, approx.

10 cm.

Seal off the flexible conduit in the floor end with a piece of tape, and install it in the floor, centered between two heating cable strings. It should reach at least 50 cm into the floor. The other end of the conduit shall end up in the junction box where the thermostat shall be installed. Then feed the sensor into the conduit from the junction box end so that the end of the sensor ends up near the floor end of the conduit.

Installation of the thermostatApplicable for: All modelsParts needed: Thermostat or regulator Junction box Mounting screws to

fasten the thermostat/regulator

Make sure that the power supply is completely disconnected. Open the thermostat by using a small screwdriver and remove the frame and the front cover. Connect the heating cable, power leads and sensor (if applicable) to the correct terminals on the back side of the thermostat/regulator. Put the thermostat/regulator in place in the junction box and attach it with mounting screws. Put the frame and front cover in place and attach by applying a light pressure until a ”click” is heard.

Full installation instructions are enclosed in the box.

Global expert in cables and cabling system

Save money with day/night temeperature controlUsing the day/night function in CDFR-001 and CDFR-002 is likely to have a very positive impact on heating expenses. It is recommended to use this functionality in all living areas like living rooms, sleeping rooms, kitchens and halls. The electricity consumption has been proven to be reduced by up to 25% compared to buildings with no such temperature control. Modern heating cable solutions are thin with less mass to be heated. This makes modern heated floors very suitable for day/night temperature control.
