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
