Installing a room thermostat will optimise the installation’s performance, adapting the heating to
the requirements of your home and obtaining enhanced comfort. Also, if the thermostat allows the
hours of functioning to be programmed (chronothermostat), it can adapt the heating system to the
hours of use of the installation.
