10c: Error Codes
E01 Water temperature sensor open or short circuit. Auto reset.
E02 Compressor temperature sensor open or short circuit. Auto reset.
E03 Evaporator temperature sensor open or short circuit. Auto reset.
E04 Compressor overload protection. Auto reset the first time, manual reset the second time.
E05 Compressor overheat protection (exceeding H95 setting). Auto reset.
E06 Compressor overheat protection (exceeding 105℃). Manual reset.
E07 Low pressure protection. Manual reset.
E08 Ambient temperature sensor open or short circuit (Optional). Auto reset.
10d: De-Icing
Only if the temperature, measured by the evaporator sensor, is below 0℃ will the de-icing
function operate.
When the compressor has been operating for 45 min (1
st
Level F45) and the evaporator
temperature is below -5℃ (2
nd
Level C-5), de-icing is activated and the indicator will be on.
When the evaporator temperature rises to 8℃ (2
nd
Level F08) or the de-icing time has been more
than 10 min (1
st
Level E10), de-icing is de activated.
10e: Operating Principle
At power on the compressor will start after the 10 min time delay (1
st
Level t10). When the water
temperature reaches 55℃ the compressor will be de activated. As the water temperature drops
below 50℃ (H55-d05) and the compressor has not been in operation for at least 10 min (1
st
Level
P10), the compressor will be activated.
During compressor operation, when the compressor temperature goes above 85℃ (2
nd
Level P85),
the liquid injection will be activated. When the compressor temperature (Axx) drops below 75℃
(2
nd
Level b75), the liquid injection will be activated.
If the compressor temperature (Axx) goes above 95℃ (2
nd
Level H95), the compressor will be de
