Warranty Information
The warranty does not cover problems related to improper installation, incorrect wiring, or improper use.
The room thermostat turns the heating system on and off to obtain the desired temperature (set temperature). It detects the air temperature and compares it with the set temperature. If the room temperature is lower than the set temperature, the thermostat turns on the boiler, and turns it off when the set temperature is reached, and so on. Energy efficiency is ensured by a TPI control algorithm, which adapts to the environment and provides tight temperature regulation with minimal energy consumption.
