9. WATER PUMP CONTROL CONNECTION
For flexibility there are 3 options of running the water pump when connected to the heat pump via the wiring
diagrams in this instruction.
P0 – Water pump will run continuously when the heat pump is turned on.
P1 – Heat pump and water pump will run until temperature is reached and then shut off.
P2 – Heat pump and water pump will run until temperature is reached and then shut off, the water pump will
restart every hour to see if there is a temperature difference, then either restart the heat pump or go back
into standby.
The default setting is P2. To change these parameters please contact your nearest Davey dealer.
