9. Errors and Warnings
9.1 Warnings
Warnings on the screen of the controller are shown with a yellow triangle and codes
W01-W07. Codes have following meanings:
WARNING W01 - Entry Air Temperature Too Low
If the entry air temperature drops under minimal air temperature (-
7°C), the generator of the
device is shuts down. Water is heated by the additional heat source, if one is selected
(chapter 7.3.15.2) . Blockage of the heat pump unit is eliminated when the air temperature is
3 °C above the minimum air temperature (above -4 °C) for 30 minutes.
The warning is shown while the activation block is triggered.
To remove the error, the area where the device is installed must be ventilated, so that
warmer air may enter the device. Should warmer air not be available, it is recommended to
manually activate the backup source
(chapter 7.3.10), or additional source (chapter
7.3.15.2) , if one is selected.
WARNING W02 - Entry Air Temperature Too High
If the entry air temperature is above the maximal air temperature (35
°C), compressor shuts
down. Water is heated by the additional heat source, if one is selected (chapter 7.3.15.2) .
Blockage of the heat pump unit is elimi
nated when the air temperature is 3 °C under the
maximal air temperature (above under 32
°C) for 30 minutes.
The warning is shown while the activation block is triggered.
To remove the error, the area where the device is installed must be ventilated, so that cooler
air may enter the device. Should cooler air not be available, it is recommended to manually
activate the backup source
(chapter 7.3.10), or additional source (chapter 7.3.3) , if one is
selected ( chapter 7.3.15.2) .
WARNING W03
– High Pressure
In the case of pressure in the cooling system of the generator being too high, the controller
shuts down the device operation. After 5 minutes, the device is reactivated. If, after
reactivation, the pressure is still too high, the device shuts down once again and displays the
warning. Should the warning appear 3 times within 1 hour, the display shows error E05, the
device shuts down and Anti-Freeze program becomes active (
chapter 8.3.3 ). See description
of error E05 (chapter 9.2). To remove error, first check if there is enough water in the hopper.
Should the warning still be displayed with enough water present, service has to be contacted.
WARNING W04
– Evaporator Temperature Too Low
If the temperature probe on the evaporator detects that the temperature is too low (-
15 °C),
the controller switches off the compressor and reports WARNING W04. Water is heated by
the additional heat source, if one is selected (
chapter 7.3.15.2 ). Blockage of the heat pump
unit is eliminated when the evaporator
temperature is 3 °C above the minimum evaporator
temperature for 30 minutes.
The warning appears in the case of the use of air canals and set low speed of the fan
(chapter 7.3.15.8), or in the case of air canal use and low entering air temperature.
