Inquiry and adjustment of SERV service settings
Service settings are closely related to the safety of the heating
system and may only be adjusted by trained specialists. For
modifications, the sliding switch (

) must be pushed
to its
position. The values can also be inquired in "AUTO"
position.

The following tables provide information on the available
SERVice setting values. The value in the second column (

corresponds to the factory setting. The numerical values in pa-
rentheses indicate the range within which the setting value can
