Water pump logic:
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.
Condition Example Water pump working logic
Heating

T1≥27.5
℃
, last

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.

Example
Tset=28
℃
Water pump working logic
Filtration pump will
start to run for 5 mins
to detect the water in
temp.
T1>Tset-1
℃
T1>27
℃
Filtration pump will enter standby mode for
another 1 hours and will not start except after
turning off the hp and restart.
T1≤Tset -1
℃
T1≤27
℃
Heat pump will start again until it meets the
condition of standby.
T1<Tset+1
℃
T1<29
℃
Filtration pump will enter standby mode for
another 1 hours and will not start except after
turning off the hp and restart.
T1≥Tset+1
℃
T1≥29
℃
Heat pump will start again until it meets the
condition of standby.
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, compr essor 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
