7.7 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.

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℃
Example
T1≥27.5℃,
last for 30
minutes
T1≦28.5℃,
last for 30
minutes
Example
Condition
Tset=28℃
T1>Tset-1℃ T1>27℃
T1≤Tset-1℃ T1≤27℃
T1<Tset+1℃ T1<29℃
T1≥Tset+1℃ T1≥29℃
Water pump working logic
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.
Water pump working logic
Filtration pump will enter standby mode for another
1 hours and will not start except after turning off
the hp and restart.
Heat pump will start again until it meets the
condition of standby.
Filtration pump will enter standby mode for another
1 hours and will not start except after turning off
the hp and restart.
Heat pump will start again until it meets the
condition of standby.
