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
activated and the error code E05 will be displayed. When the compressor temperature drops below
70℃ (2
nd
Level L70), and the compressor has not been in operation for at least 10 min (1
st
Level
d10), the compressor will be reactivated.
As the compressor temperature goes above 105℃, the compressor will be de activate and the error
code E06 will be displayed. A manual reset is required.
When the current draw is greater than the present value and lasts for 6 seconds, the compressor is de
activated and the error code E04 will be displayed, 10 minutes later the compressor will be re
activated. If the overload occurs again the system is de activated and the error cod E06 will be
displayed. A manual reset will be required or the power to the unit can be switched off and then on
again to reset the system.
10f: Adjusting
To enter any menu, press the SET button to select the item to be adjusted. Press Up and Down to do
