Regulate electric heating

Thanks to a natural complicity with the electronics, the electric heating offers possibilities of adjustment allowing to obtain real savings and moreover unequaled comfort, even more spectacular if the house or the housing is appropriately isolated.

Control energy consumption

The programming of electric radiators accurately measures the energy consumed according to the actual needs, in time and space. To know the power consumption of a heater, install an energy meter at the subscriber board, upstream of all the circuits supplying the radiators.


Any electric radiator necessarily includes a thermostat, with a position "frost free" ensuring minimum heating. By placing a thermostat in a place where the average temperature of the room is felt, the room temperature is regulated with greater precision.
- The mechanical thermostat is a rustic device, but not very precise; it is especially sensitive to aging.
- The bimetallic system, the simplest system, reacts to temperature variations with an accuracy of 2 to 4° C.
- The bulb thermostat, using the expansion or contraction of a liquid enclosed in the bulb, is accurate to 2° C.
- The vapor pressure thermostat uses a bulb filled with gas and not liquid, which gives it an accuracy of about 0.5° C.
- The electronic thermostat offers a higher accuracy, 0.2° C according to the technology it uses (0.05° C for the best appliances in common use), and most importantly, it does not go out of sync with time.

Where to place the programmable thermostat?

Place the unit in a well-accessible location, sheltered from drafts and any heat source (radiator, chimney) and out of reach of direct sunlight.


By installing a programming system, the do-it-yourselfer turns the electrical heating of his home into an extremely efficient system, both in terms of comfort and energy saving. The programming takes into account the free heat inputs (sunshine, activity in the room, etc.) and adapts the flow of each radiator to the level necessary for the activity of the room.

The programmable thermostat, also called centralized centralized scheduler, combines several elements.
- A clock controls the time slots, either by moving cursors on a dial, or by an electronic keyboard.
- The thermostats (electronic, category B) connected to probes regulate the temperature in each zone.

Pilot wire regulation

The centralized programmer controls the operation of each radiator via a control wire called "pilot wire".

All the pilot wires are connected to a terminal block at the subscriber board, from which a wire connected to each of the terminals of the programmer corresponding to a control zone (here: day zone and night zone).

Cycles and zones

These devices program heating according to two criteria: the repetition cycle of the same setpoints and the application areas of each setpoint.

The programming cycle adjusts the heating by time zones, depending on the activity of the occupants.
- The daily programming defines the temperature ranges over 24 hours.
- Weekly programming takes into account the variations of the rhythms of life during the week (day of school rest, weekend, etc.).
- The derogation makes it possible to temporarily modify the programming when the conditions differ exceptionally from those on which the setting is based.

Programming areas consist of rooms where the same level of activity prevails at the same time.
- The sleeping area mainly concerns the rooms, with also the bathrooms adjacent to them.
- The day area covers the rooms where the daytime activity takes place: living room, living room, kitchen, bathroom.
- A single area is acceptable for a modest-sized dwelling (less than 60 m2 approximately).

Hours and zones

Hours and zones

For each time of the day, program a temperature adapted to your rhythm of life. Assign a set temperature to each zone. Here: a day area for the living room, the kitchen, the living room and the bathroom, and a sleeping area for the bedrooms.
