The on-off TP Indoor Thermostat allows setting of room temperature with an adjustment knob within the range 8…30ОС; the on-off TPP thermostat with LCD display allows setting of the room temperature within the range from 8…35ОС in a day/night mode.
If the room temperature drops below the preset value, the thermostat generates an output signal that opens the valve and switches the fan on. If the indoor temperature exceeds the preset value, the thermostat will switch over and generate a signal to close the valve and switch off the fan.
The thermostat can be used in both, closed loop and open air circulation.
