Disturbances in comfort
In most cases, the indoor module notes operational interference (opera-
tional interference can lead to disturbance in comfort) and indicates this
with alarms and shows action instructions in the display.
Info-menu
All the indoor module measurement values are gathered under menu 3.1
in the indoor module menu system. Looking through the values in this
menu can often simplify finding the fault source.

In the event of an alarm, some kind of
malfunction has occurred, which is
indicated by the status lamp changing
from green continuously to red con-
tinuously. In addition, an alarm bell
appears in the information window.
Alarm
In the event of an alarm with a red
status lamp a malfunction has oc-
curred that the indoor module cannot
remedy itself. In the display, by turn-
ing 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 indoor module to
aid mode.
info / action 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 most cases it is enough to select "reset alarm" to correct
the problem that caused the alarm. If a green light illuminates 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 returns, contact your
installer.
aid mode ”aid mode” is a type of emergency mode. This means that the
indoor module produces heat and/or hot water despite there being some
kind of problem. This can mean that the indoor module's compressor is
not running. In this case the immersion heater produces heat and/or hot
water.
