The TKBETZ1036 is a heating thermostat with LCD screen and built-in Z-Wave technology. The thermostat is designed to fit into your flush box and control your electric heating or on/off actuator valves used in hydronic heating. The thermostat is mains powered and has an internal temperature sensor built in and an external sensor included in the scope of delivery. To use both sensors you have to connect the external sensor to the thermostat. Then the thermostat allows to switch between the 2 different sensors. The display shows the value of the chosen temperature sensor and allows adjusting the temperature of the connected heating system. The temperature can be adjusted in steps of 1° C.
