Option 1: Water pump is related to compressor’s operation to start or stop. (Parameter
P3=0)
When heat pump turns on, filtration pump will start first and then fan motor and compressor.

Filtration pump will enter standby mode
for 1 hours(old version: 2 hours) and will
not start except after manual power off
and restart. Compressor and fan motor
stops first and filtration pump will
stop after 5 mins.

Note: If the water volume of the swimming pool is small, water temp reaches T1≥Tset+1
℃
and last for 5 mins, heat pump will stop first and then filtration pump stops, but it will not
entry standby mode for 1 hour. If water temp drops to T1≤Tset-1, heat pump will start again.
Option 2: When the heat pump is on (running or standby), filtration pump will always be on.
(Parameter P3=1)
When turn on heat pump, filtration pump starts first and then fan motor and compressor
start. When reaches to the condition T1≥Tset+1 and last for 3 mins, compressor and fan
motor will stop, filtration pump will always be on.
It will run for 1 minute after turning off the hp.
NOTE :
Tset = Tseting water temperature
For example : Tset = 28
℃
Tseting water temperature in your pool heat pump
Tset-1 = less 1
℃
than Tseting temperature
Tset- 1 = 28-1=27
℃
Tset+1= more 1
℃
than Tseting temperature
Tset+ 1 = 28+1=29
℃
