Disturbances in comfort
Alarm
Basic actions
Low hot water temperature or no hot water
Low room temperature
In most cases, the control module notes a malfunction
and indicates this with alarms and shows instructions
to rectify it in the display. See "Manage alarm" for in-
formation about managing alarms. If the malfunction
does not appear in the display, or if the display is not lit,
the following troubleshooting guide can be used.
In the event of an alarm, some kind of malfunction has oc-
curred, which is indicated by the status lamp changing from
green continuously to red continuously. In addition, an alarm
bell appears in the information window.
If the alarm has not been reset, contact the installer for
proper repair.
In the event of an alarm with a red status lamp a mal-
function has occurred that the heat pump and/or control
module cannot remedy itself. In the display, by turning the
control knob and pressing the OK button, you can see the
type of alarm it is and reset it. You can also choose to set
the installation to aid mode.

Here you can read what the alarm
means and receive tips on what you can do to correct
the problem that caused the alarm.
reset alarm In many cases, it is sufficient to select
“reset alarm” in order for the product to revert to nor-
mal operation. If a green light comes on after select-
ing “reset alarm”, the alarm has been remedied. If
a red light is still visible and a menu called “alarm”
is visible in the display, the problem that caused the
alarm remains. If the alarm disappears and then re-
turns, contact the installer.

”aid mode” is a type of emergency mode.
This means that the installation produces heat and/or
hot water despite there being some kind of problem.
This can mean that the heat pump's compressor is
not running. In this case any electrical addition pro-
duces heat and/or hot water
If the operational interference is not shown in the dis-
play the following tips can be used:
Start by checking the following items:
• The switch's position.
• Group and main fuses of the accommodation.
• The control module's miniature circuit breaker.
• Correctly set load monitor (if installed).
This part of the fault-tracing chapter only applies if the
water heater is installed in the system.
• Closed or choked filling valve for the hot water.
– Open the valve.
• Mixing valve (if there is one installed) set too low.
– Adjust the mixer valve.
• Control module in incorrect operating mode.
– If mode "manual" is selected, select "addition".
• Large hot water consumption.
– Wait until the hot water has heated up. Tem-
porarily increased hot water capacity (temporary
lux) can be activated in menu 2.1..
• Too low hot water setting.
– Enter menu 2.2 and select a higher comfort
mode
• Too low or no operating prioritisation of hot water.
– Enter menu 4.9.1 and increase the time for
when hot water is to be prioritised.
• Closed thermostats in several rooms.
– Set the thermostats to max, in as many rooms
as possible.
• Adjust the room temperature via menu 1.1, in
-
stead of choking the thermostats.
• Control module in incorrect operating mode.
– Enter menu 4.2. If mode "auto" is selected,
select a higher value on "stop heating" in menu
4.9.2.
– If mode "manual" is selected, select "heating".
If this is not enough, select "addition".
• Too low set value on the automatic heating con-
trol.
– Enter menu 1.1 "temperature" and adjust the
offset heating curve up. If the room temperature
is only low in cold weather the curve slope in
CAUTION
Selecting "aid mode” is not the same as correcting the
problem that caused the alarm. The status lamp will
therefore continue to be red.
IMPORTANT
When reporting a fault, always enter the serial number
of the product (14 digits).
