Depending on your existing heating installation, the table below will help you identify the features offered by the product.
Electric heating with pilot wires Electric heating without pilot wires Boiler
“PRESENT” mode: Your heating programmer
manages the pilot wire of the radiators (Chauffage
SMS is at rest). If your installation is devoid of a
heating programmer, the control is managed by your
heater.
“ECO” mode: Chauffage SMS applies a frost
protection signal to the pilot wire on the radiators
(your heating programmer is disconnected from the
pilot wire of the radiators).
If you want to obtain a higher ECO temperature than
frost protection, it is necessary first to install a
temperature sensor and to set this setpoint by SMS.
Then make sure that the heating programmer is not
in the anti-freeze or off position.

only acts on the water circulator of the
heating circuit.
