Water pump running logic and error code 'ON'.
There are two options for water pump running.
Option 1:Water pump starts or stops in relation to heat pump operation.
Water pump starts 60s before compressor, water pump start 30s and then detect the water flow switch. When the
heat pump enters standby mode, water pump will stop 60s after compressor stops. Water pump will restart to
running for 3 min then stop when the standby time is over 2 hours.
HP working mode
Heating mode
Cooling mode
In this case, it is unnecessary to deal with Error code 'ON' if 'ON' occurs in water pump's 2 hours standby period.
Option 2
No matter when the heat pump is on (running or standby), water pump will always be running.
Water pump will run for 1 minute after manually turn off.
Condition
(Tset:Setting water temp.
T1: Inlet water temp.)
T1>Tset-1,
and last for 30 min
T1<Tset+1,
And last for 30 min
Example:
Tset = 28℃,
T1>27℃,
last for 30 minutes
T1<29℃,

mode for 2 hours and will not start
except turn off power supply and

minutes after the water pump exit
the standby mode to detect the
water temp. T1 again.
