Getting to know the thermostat

The Wiser radiator thermostat (hereinafter referred to as thermostat) uses integrated temperature sensors to control the flow of water through a radiator, thereby regulating the temperature in a room. The target temperature and switching times are set in the Wiser app or Wiser Heat app (hereafter, both apps are referred to as the Wiser app).
