Error elimination
DANGER!
Danger of death due to electric shock!
– Disconnect the unit from the power supply
immediately if safe operation can no longer
be guaranteed, e.g. if there is visible
damage.
– Disconnect the unit from the power supply
before opening the housing.
– All works on the open unit may only be car-
ried out by a specialist.
The controller is a quality product and was
designed for many years of continuous use.
Therefore, note the following points:
– The cause of an error is often not the con-
troller but one of the connected compo-
nents.
– The following notes for identifying errors
refer to the most common causes of errors.
– Do not send the controller in until you are
sure that none of the causes of errors
described here apply.
General errors
The unit and components are manufactured using
state-of-the-art production methods and tested
several times to verify their correct function. How-
ever, if alarms should occur, please check the
functions as detailed in the list below. For systems
with an indoor unit and outdoor unit, refer to the
chapter "Troubleshooting and customer service" in
both operating manuals. Please inform your dealer
if the unit is still not working correctly after all func-
tion checks have been performed!
