Factory reset Key

▶ In order to carry out the factory reset, press the key on Key
longer than 5 seconds.
The Key loses all connections and then goes directly into
the pairing mode, i.e. it flashes yellow for up to 3 minutes
and all wireless participants must be reconnected.
Before the wireless participants can be reconnected, they must
first be separated. To do this, separate the control unit by
means of the service menu (installer). Separate the outside
temperature sensor by means of a reset.
8 Troubleshooting
If a fault cannot be corrected:
▶ Confirm the fault.
▶ Faults that are still active are displayed once again the next
time the control unit returns from the idle state.
▶ Call an authorised specialist or customer service and give
the fault code and sub-code, as well as the ID number of the
user interface.
