Installing and connecting a room thermostat

Control its energy consumption is a "plus" offered by the room thermostat. It acts on the boiler and the tuning is done by heating the thermostatic valves. Install an electronic thermostat depends on the strength of the coils and the presence of a pilot wire.

Choose a room thermostat

A room thermostat can remotely control the operation of a boiler for heating the central or electric heaters. In principle, the models are the same for both applications but their mode of connection is different.

A room thermostat also allows you to program the heating mode depending on the occupancy or changes in outside temperature.

Finally, there are electronic thermostats wireless control box, installed in the habitable zone, battery operated which makes the choice of location.

Electronic thermostat: select the connection type

In the event that the thermostat controlling electric heaters, you may need to install a power switch:

- Coil wireless driver, power below 1100 W = no switch;
- Coil wireless driver, power above 1100 W = switch; 
- Heater with pilot wire, power less than or greater than 1100 W = no switch. 

Generally, if the thermostat acts on a central heating boiler, the power switch is not necessary
The choice of the intensity of the contactor depends on the total power of coils connected:
- Total power of the coil from 1 100 to 4400 W = 20 A contactor;
- Total power of the coil from 4 400 to 8 800 W = 40 A contactor;
- Total power convectors 8800 to 13 200 W switch = 60 A.

Install a room thermostat: the laying

Determine the best location. The thermostat should be at eye level , away from direct heat sources (radiators, fireplace, sun). If it is not wireless, it should also allow it to be easily connected to the boiler or the line that feeds the electric heaters.

Drill holes as the template of the thermostat, plug and screw it on the wall.

Connecting a room thermostat

 Turn off power at circuit breaker before working on the main power grid.
Thermostat wiring depends on the brand and type of heating, electrical or not, with or wireless driver. observe the indications provided in the installation guide, especially for the choice of drivers, their color, their nature, diameter, and the instructions for the line protection and equipment.
