"Auxiliary operation" is a type of emergency mode. This
means that the installation attempts to produce 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 oper-
ation. In this case, any electric additional heat produces heat
and/or hot water.
• If RMU S40 is set to "Night mode", the display is off. (See
Menu 1 – Night mode.)
Caution
To select "Auxiliary operation", an alarm action
must be selected in menu 7.1.8.1 – "Alarm actions"
in the main product.
Caution
Selecting "Auxiliary operation" is not the same as
correcting the problem that caused the alarm. The
status lamp will therefore remain red.
