The pilot wire electric heating solution allows you to manage several temperature zones with a single thermostat and several modules and thus, have different temperatures in your rooms.
The main zone is regulated using the temperature read by the thermostat and the set point of your program. The comfort temperature of the radiators connected to the module(s) in this zone should be set to the maximum value to allow fine control.
The secondary zones use the internal control of the radiators and can be programmed with pilot wire orders. The comfort temperature of the radiators connected to the module(s) in this zone should be set to the desired value in the room.
