7.7 Water pump logic
Option 1: Water pump is related to heat pump operation to start or stop.
Filtration pump starts 60s before compressor, filtration pump start 30s and then the water flow switch detect
flow. When the heat pump enters standby mode, filtration pump will stop 60s after compressor stops.
Filtration pump will restart running for 3 minutes then stop when the standby time is over 2 hours.
Condition
Heating T1>Tset-1, last
mode for 30 minutes
Cooling T1<Tset+1, last
mode for 30 minutes
Option 2:
When the heat pump is on (running or standby), filtration pump will always be on.
It will run for 1 minute after manually turn off.
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
Filtration pump will enter standby mode for 2 hours
and will not start except after manual power off and
T1>27℃, last
restart. Heat pump will restart 3 minutes after the
for 30 minutes
filtration pump exit the standby mode to detect the
water temp. T1 again.
