Disturbances in comfort

In most cases, F110 notes a malfunction (a malfunction can
lead to disruption in comfort) and indicates this with alarms,
and instructions for action, in the display.

Info menu

All the heat pump measurement values are gathered under
menu 3.1 in the heat pump menu system. Looking through
the values in this menu can often simplify finding the source
of the fault. See help menu or user manual for more inform-
ation about menu 3.1.

alarm" to correct the problem that caused the alarm. If the
alarm recurs, the problem that caused the alarm remains.
If the alarm disappears and then recurs, see the
troubleshooting section (page 33).
aid mode "aid mode" is a type of emergency mode. This
means that the heat pump produces hot water despite there
being some kind of problem.
This can mean that the heat pump's compressor is not run-
ning. In this case the immersion heater produces hot water.
Caution
Selecting "aid mode" is not the same as correcting
the problem that caused the alarm. The alarm
symbol will remain displayed.
