ILAHP Inverter Extreme Air-to-Water Heat Pump
Parameter H (System Parameter)
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 flow switch after P04-10s. If the water flow switch is inspected as ON for 10s successively, the compressor can be started.
The ILAHP provides the ability to control the main and Domestic Hot Water circulators based upon the measured outdoor air
temperature.
The value of parameter P01 controls the logic of the main circulator output when the outdoor temperature is below the value of
parameter R40, the pump will operate according to the parameter P01. When the air temperature is above R40, the pump will revert
to economy mode and always operate as if P01=1, where the pump shuts down two minutes after the compressor stops, and restarts
only when the measured water temperature falls to the restart point.
The same logic applies to the DHW circulator function, according to the outdoor temperature and value of parameter R41.
If either or both of these functions is not desired, simply set the value of R40 or R41 to the maximum of 140°F. This will effectively
shut off this feature.
