HEAT PUMP ELECTRONIC BOARD
19.2 Parameters check in the electrical board
To check the parameters of hydraulic box (PCB-1), open door 2 and you’ll see the PCB like following, the digital display will show the temperature of outlet water in
normal condition (‘0’ will display if the unit is off or error code will display if error occurs). Long press the check button and the digital display will show the operating
mode. Then press the check button in sequence. The digital display will show the value, the implication of the value illustrated in the diagram below:
