Ensuring the right temperature inside a building affects its comfort, regardless of the season and weather conditions outside. In order to maintain the room temperature at the required level in an unmanned manner, the heating, ventilation and air conditioning systems must be controlled by feedback. In such an application, the thermostat with temperature sensor perfectly fulfils its role.

The W1209 thermostat is equipped with a temperature sensor which measures temperature in real time. The temperature is converted into a voltage signal - when the programmed threshold value is exceeded, the voltage is applied to the coil of the built-in relay. The output relay switches on and off the power supply to the ventilation, air-conditioning and heating circuits, according to the programmed parameters of the thermostat.
