If something is wrong

The control unit provides a lot of information about faults and how to remedy them. The control unit
incorporates advanced functions to monitor and protect your heat pump. This means there is no risk
involved in resetting an alarm. If a fault persists, you should contact the installer.

Alarm examples and what to do

Cause
If you press "Info" and then turn
the knob you will see informa-
tion about the possible causes
and how you can remedy the
fault yourself.

If the control panel is dark

Possible faults:
• The fuses or MCBs (miniature circuit-breakers) in your fuse box.
This is what to do: Check the fuse (or MCB) for your heat pump. If the small plate at the bottom of
the fuse has come off, the fuse has blown and must be replaced. If you have MCBs, and they have
tripped, move the switch to the up position.
Note that the heat pump cannot restart until after 15 minutes. This delay is needed for technical
reasons!
• If the heat pump MCB has tripped, this is what to do:
The C series
Reset by pushing the
toggle to the up position.
