Water ow failure (water cycle model):
•
After the circulating water pump starts, it detects that the water flow switch is in the off
state for 10 seconds, then heat pump stops.
•
At this time, the controller displays the water flow switch fault alarm code
“01E”.Periodically (1 minute) restarts the water pump and 10 seconds later, the flow
switch is detected.
•
If water flow switch is closed, heat pump will goes to normal running.
•
If the fault occurs 3 times within 1 hour, the fault is locked and heat pump will not
starts.
Water temperature too low protection at cooling mode(water cycle heat
pump)
•
In the cooling mode with compressor running for 5 minutes, if detects that the outlet
water temperature is <5 °C for continuous 5 seconds, heat pump enters sub cooling
protection.
•
The compressor and the fan stop running, And the water pump operates normally.
When the outlet water temperature is detected to be ≥7 °C, heat pump exits the sub
cooling protection and enters normal operation.
Water temperature too high protection at heating mode (water cycle heat
pump)
•
In the heating mode, after compressor running for 5 minutes, if the water temperature
is detected by continuous 5S ≥65 °C, it is judged that the outlet water temperature is
too high.
•
It will shutdown heat pump for protection and when the outlet water temperature is
detected to be ≤60 °C, the protection is withdrawn.
Temperature sensor failure:
•
Heat pump will stop once the water tank temperature sensor or outlet water
temperature sensor or ambient temperature sensor is faulty.
•
When absorb or exhaust or evaporator coil or water return temperature sensor is
faulty, electric heater is allowed to operate.
•
When the return water temperature sensor fails, the return pump is allowed to run (do
not judge the return water temperature)
High exhaust temperature failure:
•
After the compressor starts running for 1 minute, when the exhaust gas temperature is
detected to be higher than or equal to the exhaust high temperature protection value
by 110
℃
for 10 consecutive seconds, an high exhaust temperature alarm occurs and
the compressor stops.
•
At this time, controller shows high temperature fault alarm code "02E". When the
exhaust temperature drops back to 90
℃
, the alarm is released and the normal
temperature control function is restored.
•
If high temperature fault protection appears 3 times within half an hour, the controller
will lock the protection and the compressor will be locked in the shutdown protection
state. At this time, only the shutdown and restarting can unlock the compressor.
