Disturbances in comfort

In most cases, the heat pump notes operational interference
(operational interference can lead to disturbance in hot
water comfort) and indicates this with an alarm in the dis-
play.

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.
