How parameter P3=0 works - depends on the operation of the compressor.
When the heat pump turns on, the water pump will start, then the fan and at last the compressor.
Heating mode
Cooling mode
Water pump will start to
run for 5 mins in order
to detect the water tem-
perature
Note: If the water volume of the swimming pool is small, water temperature reaches T1≥Tset+1°C
and lasts for 5 minutes. In that case the heat pump will stop first and then the water pump, but it will
not entry standby mode for 1 hour. If the water temperature drops to T1≤Tset-1, the heat pump will
start again.
How parameter P3=1 works - always running.
When the heat pump turns on, the water pump starts, then the fan motor and and at last the com-
pressor. When the heat pump condition reaches T1≥Tset+1, it lasts for 3 mins. In that case the
compressor and fan motor will stop.
