DIP Switch S1
Coding Switch 5
Switch position Service mode
ON
ON Service mode

Following an electric power failure, the system starts in service mode with default parameters for ser-
vice purposes. Changes to parameters are not permanently saved (power failure). Coding Switch 5 of
DIP Switch S1 may only be set ON to invoke service mode.
Service mode must always be deactivated for normal system operation (Coding Switch 5 of DIP
Switch S1 must be set OFF)!

1234567
OFF Firmware update mode
Coding Switches 6 and 7 of DIP Switch S1 may only be set OFF for downloading firmware. At this
setting the controller awaits firmware update from a connected Service PC. Firmware update mode
must always be deactivated for normal system operation (Coding Switches 6 and 7 of DIP Switch S1
must be set ON)!
If a switch position is changed after startup, the basic parameters for the set temperature range will be
loaded the next time the controlled is started (power failure) and the controller w ill perform first s tart. In
view of the large number of parameters, the basic parameters can also be loaded with the operating
terminal (see Section 8 - Menu Structure).
