Inverter Air-to-Water Heat Pump
Parameter H (System Parameter)
H01——Auto Start (Yes/NO)
When H01 = 0, the heat pump haven’t the auto restart function for regular ON-OFF. That is to say:
Every time the heat pump is connected to electricity, it is in power OFF status.
When H01 = 1, the heat pump has the auto restart function for regular ON-OFF. That is to say:
When the heat pump is connected to electricity, it will keep the power ON or OFF status before power failure.

Parameter P (Pump Parameter)
In normal modes of cooling, heating and electrical heating, the water pump will be started at least P04 time earlier and shut down
2 minutes later than the compressor. The water pump shall be started all the time during defrosting. The controller starts to inspect
water ow switch after P04-10s. If the water ow switch is inspected as ON for 10s successively, the compressor can be started.
