Every Somfy thermostat is used to manage a boiler / heat pump / floor heating system / electric radiator system with a dry contact input.
The cabled thermostat is recommended to replace an old cabled thermostat that is already positioned at the correct height (1.5m, not directly exposed to sunlight). The radio thermostat is used to replace an old cabled or radio thermostat and requires a receptor to communicate with your heating system.
