12.3.2 Fault handling
When leaving the “Commissioning“ menu, a check is made to see if the outside sensor
is connected or a sensor value is received via bus. If there is no outside temperature, or
in the case of a short-circuit, fault status message “Outside temp sensor error“ will
appear. Internally, the controller continues to operate using 0 °C as a backup value.
If outside temperatures from other outside temperature zones are available via bus,
they will be used as backup values until the error has been rectified.
Only one outside temperature may be present in the same zone. If several controllers
transmit their outside temperature in the same zone, fault status message “>1 outside
temp sensor HC 1“ (or HC 2 or HC 3) will be delivered.

Solar intensity sensor error
• Solar intensity sensor not connected
• Bus communication interrupted
• Solar zone not correctly set (transmit-
ter and receiver must use the same
solar zone)
Nonurgent message; must not be ac-
knowledged
21
>1 solar intensity sens in
zone
More than one solar intensity sensor in
the same solar zone.
Urgent message; must be acknowledged

Wind speed sensor error
• Wind speed sensor not connected
• Bus communication interrupted
• Wind zone not correctly set (transmit-
ter and receiver must use the same
wind zone)
Nonurgent message; must not be ac-
knowledged
