Wireless Room Thermostat ELEKTROBOCK BPT22 is the ideal solution for situations where it is costly or completely impossible to run wires from the thermostat to the boiler. The large backlit display allows for operation even in the dark. The receiver is equipped with a self-learning code system and E-EPROM memory, which retains the stored code even during a power outage. The BPT22 operates with two-way communication at a frequency of 433.92 MHz. The range of the set can be up to 35 m (in built-up areas).

The thermostat is now offered under the designation BT22.
