To remove error, check fan speed
(chapter 7.3.15.8)
or ensure higher entering air
temperature.
Should warmer air not be available, it is recommended to manually activate the backup
source (
chapter 7.3.10
), or additional source (
chapter 7.3.3
), if one is selected (

WARNING W05
– Evaporator Temperature Too High
If the temperature probe on the evaporator detects that the temperature is too high, the
controller switches off the device and reports WARNING W05. The device is blocked for 30
minutes, the additional source
(chapter 7.3.15.2)
if one is selected
becomes active.
To remove the error, the area where the device is installed must be ventilated, so that cooler
air may enter the device. Should error not be removed, service has to be called, and manual
activation of the backup source
(chapter 7.3.10)
, or additional source (
chapter 7.3.3
), if one is
selected (
chapter 7.3.15.2
WARNING W07
– External Source Temperature Too High
If external source temperature exceeds maximal permitted temperature
(
105 °C)
, the use of
external source ceases. For the reactivation of external source use, the temperature must
drop for 5°C. Device operates according to the set programme without using the external
source. If manual alternative operation is active
(chapter 7.3.3)
sanitary water heating is
interrupted until external source is once again available.
9.2 Errors
Errors are shown on the controller display with a red triangle and codes E01-E09. Codes
have the following meanings:
Error E01
– Water Temperature Probe Error
Should there be a water temperature probe error, the device shuts down, and the additional
chosen source or internal electric heater are also inactive. Only ventilation operates in the
case that it is set to. Service has to be called to remove the error.
Error E02
– External Source Temperature Probe Error
Should there be an error on the external source temperature probe, the device continues to
operate, but operation with external source is deactivated
(chapter 8.2)
To remove the error,
one must first check if the installation of the probe was carried out compliant with the
installation and instruction manual (Installation of Temperature Probe for External Source). If
the installation was carried out properly, probe operation has to be checked and, if required,
service called. Use of external source is not possible until error is removed.
Error E03
– Entering Air Temperature Probe Error
Should there be an error on the entry air temperature probe, the device continues to operate
(using the evaporator temperature). Should the error be displayed and device not be
operational due to the air temperature being too low, 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
). Service has to be called to remove the error.
Error E04
– Evaporator Temperature Probe Error
Should there be an error on the evaporator temperature probe, the device continues to
operate, but only to a minimal air temperature difference of 10
°C. Should the error be
displayed and device not be operational due to the air temperature being too low, 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
). If, along with Error E04, Error E03 also
