The Elektrobock PH-PK20 wireless receiver serves as a receiving unit for heating boilers, which receives signals from the central unit and switches the boiler on or off accordingly.

The central unit determines when the boiler needs to be switched on based on collected temperature data and the set program. The signal is sent to the PH-PK20 receiver, which then switches the boiler on or off. The PH-PK20 also sends a confirmation signal back to the central unit to confirm receipt of the command. If this does not occur, the central unit will display an error message.

The receiver features LED indication of operational status. This allows you to easily perform a quick visual check to determine the current status.

The PH-PK20 receiver connects to the boiler using two wires.
