aid mode “aid mode” is a type of emergency mode. This means that
the indoor module produces heat and/or hot water, even though there
is some kind of problem. This could mean that the heat pump’s com-
pressor is not in operation. In this case, the immersion heater produces
heat and/or hot water.
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
Always state the product’s serial number (14 digits) when re-
porting a fault. See chapter Serial number on page 7.
