aid mode “aid mode” is a type of emergency mode. This means that
the electric boiler/indoor module produces heat and/or hot water, even
though there is some kind of problem. This could mean that the heat
pump’s compressor is not in operation. In this case, the immersion
heater produces heat and/or hot water.
Caution
To select aid mode an alarm action must be selected in the
menu 5.1.4.
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.
If the alarm does not reset, contact your installer for suitable remedial
action.
NOTE
You need the product's (14 digit) serial number for servicing
and support.
See chapter "Important information/Serial number".
