11 Disturbances in comfort
Alarm
Basic operations
Low hot water temperature or no hot water
Low room temperature
In most cases, the controller detects if malfunctions
occur and indicates this with alarms, and shows in-
structions to rectify them on the display. See “Man-
age alarms” for information about managing alarms.
If the malfunction does not appear on the display,
or if the display is off, the following troubleshooting
guide can be used.
In the event of an alarm, some kind of malfunction
has occurred, which is indicated by the status lamp
changing from green to red. In addition, an alarm bell
appears in the information window.
If the alarm does not reset, contact your installer for
suitable remedial action.
In the event of an alarm with a red status lamp, a
malfunction has occurred that the heat pump and/or
control module cannot repair by itself. By turning the
control knob and pressing the OK button, you can see
in the display what type of alarm it is and reset it. You
can also choose to set the system to aid mode.
Alarm information / actions 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” for the product to revert to normal oper-
ation. If a green light comes on after selecting “Reset
alarm”, the cause of the alarm has been resolved. If a
red light is still visible and a menu called ”Alarm” is vis-
ible in the display, the problem that caused the alarm
remains. If the alarm disappears and then returns, con-
tact your authorised installer or a service company.
Aid mode “aid mode” is a kind of emergency mode.
This means that the system is producing heat and/or
hot water despite there being some kind of problem.
This could mean that the heat pump’s compressor is
not working. In this case the electric additional heat
produces heat and/or hot water.
If the operational interference is not shown on the
display, the following tips can be used:
Start by checking the following items:
• Position of the switch.
• Fuses and mains fuse.
• The house’s residual-current device.
• Correctly set current sensor (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) positioned
too low.
– Adjust the mixer valve.
• Control module in incorrect operating mode.
– If “manual” mode is selected, select “add.
heat. only”.
• High hot water consumption.
– Wait until the hot water has heated up. Tempo-
rarily increased hot water output (temporary lux.
mode) can be activated in menu 2.1.
• Hot water setting too low.
– Go to menu 2.2 and select a higher comfort mode.
• Too low or no priority for hot water.
– Go to menu 4.9.1 and increase the time for
which hot water is to be prioritised.
• Closed thermostats in several rooms.
– Fully open the thermostatic valves in as many
rooms as possible.
• Adjust the room temperature via menu 1.1, in-
stead of turning the thermostats.
• Control module in incorrect operating mode.
– Go to menu 4.2. If “auto” mode is selected,
select a higher value for “stop heating” in menu
4.9.2.
NOTE
Selecting „aid mode” is not the same as correcting
the problem that caused the alarm. The status lamp
will therefore remain red.
