Page 37 ILAHP Inverter Extreme Air-to-Water Heat Pump Meaning of Each Parameter Parameter A (Protection Parameter) Anti-Freeze Protection Detect Malfunction Cooling mode: After the compressor starts, it will detect water outlet temperature (T02). If T02≤A01 or the suction pressure is lower than A02 for 10s, the unit will enter anti-freezing protection. Note: After the compressor has run for 5min, the unit starts to detect its suction pressure.
Page 38 ILAHP Inverter Extreme Air-to-Water Heat Pump Parameter D (Defrost Parameter) Requirements to enter defrosting ① Check the suction pressure for 1 min. after the compressor starts, and when suction pressure is ≤D05, defrosting timing shall be started. ② If the suction pressure sensor failure, the unit will start timing defrost, and the defrost cycle is D03, defrost time is D04. Requirements to stop defrosting ① After starting defrosting, when T09≥D02,and T06≥D01, the unit stops defrosting;...
Page 39 ILAHP Inverter Extreme Air-to-Water Heat Pump Parameter F (Fan Parameter) Normally, in heating mode or cooling mode, fan will start up 10s ahead of compressor and 30s later to shut off. Fast mute function When the fast mute function is turned on, the fan will run according to the parameter F13 if it needs to be turned on, and exit the mute function after 8 hours.
Page 40 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.
Page 41 ILAHP Inverter Extreme Air-to-Water Heat Pump Parameter R (Temperature Parameter) When the mode is hot water mode and tank temperature<R01-R04, the unit is running in hot water mode and the target temperature is R01. When water tank temperature≥R01+R05, the unit will exit hot water mode. The unit use the hot water side to defrost when in defrosting.
