7.5 Failure reports
Please find below table containing list of failure reports with their explanation and suggested solution.
In order to physically locate the sensor please refer
to section 3.6 Block wiring diagram of the PCB
board
and/or section
3.7 Expanded view.

app. 1-2 minutes
after turning on;
acoustic warning None/Weak/High water flow;
No closure of the flow switch
or failure of the flow switch
Flow switch
Set the water flow to 4-6m

/h or
check the flow switch

Please refer
to section 7.6
Troubleshooting
EE7
Optical warning Electric leakage protection
-
Check the power supply of the
unit, circuit breaker. In order to
remove EE7 optical warning,
power supply needs to be turned
off and on
EE8
Acoustic warning Failure of the cable
communication of the
controller
-
Check the control cable between
the control board and the control
digital panel
EE9
Heat pump
decommissioned High/Low pressure switch
protection In order to remove EE9 optical
warning, power supply needs to
be turned off and on
-09
Heat pump
decommissioned Temperature sensor(s) failure
5kΩ
Temperature sensors or their bus
inputs are burnt out. Sensors
and/or possible the whole
regulator with motherboard must
be replaced.
EE C
Heat pump
decommissioned Ambient air temperature
lower than -
15°C
-
Please check ambient air
temperature of the condensing
unit. Should the temperature be
lower than -
15°C, the heat pump
will not work due to security
reasons. In such case there is
seemingly nothing wrong with
your heat pump. Should the air
temperature be higher than -
13°C, the sensor must and/or
motherboard must be replaced.
