Warning (yellow)
The air handling unit remains in operation in the event of a
warning, but can deviate from standard operation.
1. Slow flash:
Condensate - There is condensate in the cooling module
which has not been automatically removed. Module out
of operation.
• Remove condensate manually from the condensate
tray.
• Clean the condensate system (see page 28), or
CALL SERVICE.
2. Rapid flash:
Cooling module compressor locked (stopped). Module out of
operation. Condenser overheated for an extended period.
• Check whether the alarm cancels after power has
been cut off to the unit or CALL SERVICE.
3. Rapid double flash at 2 second intervals:
Filter needs replacing. Operation will continue unchanged.
• Change filters and cancel service (see page 29) or
CALL SERVICE.
4. Light on constantly.
Technical fault on temperature sensors (RT, OTV, CdT, OT,
EvT, EVi, EVo or HG), flow control or CO
module will be out of action if faults CdT, OT, EvT, EVi, EVo
or HG occur. Certain internal control functions are working
insufficiently if faults RT and OTV occur.
• CALL SERVICE.

Alarm (red)
The air handling unit will stop to prevent damage in the
event of an alarm.
1. Slow flash:
Low temperature - Low outside temperatures can make
it necessary to protect the unit against ice formation. In
such instances, the low temperature alarm will activate.
The unit will automatically try to start up once every hour
if the start signal is still active.
2. Rapid flash:
Condensate - There is condensate in the air handling unit
which has not been automatically removed.
• Remove condensate manually from the condensate
tray.
Units with no condensate drain:
• If the alarm repeats, it may be necessary to install a
condensate drain or pump. CALL SERVICE.
Units with condensate drain/pump:
• Clean the condensate system (see page 28), or
call service.
• The water lock is wrongly fitted. Installation can be
corrected by authorised experts.
• Condensate pump defective. CALL SERVICE.
3. Rapid double flash at 2 second intervals:
Filter change required.
• Change filters and cancel service (see page 29) or
CALL SERVICE.
4. Light on constantly.
Critical fault on temperature sensors (IT, ETV) or a fan.
• CALL SERVICE.
