Boiler receiver - wall-mounted PH-PK20

Product detailed description

Features of the PH-PK20 wireless receiver:

Switches the boiler on and off according to information sent from the central control unit. The central unit (CU) operates according to the selected program and, upon reaching the set temperature, sends a signal to the PH-PK20 to switch off the heating water heating. Upon receiving a signal from the central unit, the PH-PK20 confirms receipt of the information back. If the CU does not receive a response, it displays Error on the LCD. The operator is thus immediately informed of communication problems. All operating states are indicated by LEDs.

If the PH-PK20 does not receive any information for more than 6 hours, it switches to emergency mode (heats for 2 minutes and the boiler is switched off for 8 minutes).
