8.1  General 
 
This section describes the functions and entries for time switch catalogs and cal-
endars. 
Possible entries vary depending on the configuration. It is set in Configuration 1: 
Main Index > Configuration > Configuration 1 > TSP function 
Main Index > Configuration > Configuration 1 > TSP steps 
The time switch catalog/calendar available in auxiliary has the set entries Off and 
On: 
Main Index > Configuration > Configuration 2 > Aux TSP output 
If no element is active at a higher priority (e.g. Manual Operation <> Auto), the 
plant can be switched to off or any stage using a time switch catalog (for analog 
controlled fans to the given stage setpoint). A maximum of 6 switching entries are 
possible per week. 
The calendar Fix Off (in operating mode only) override the calendar exception and 
this in turn overrides the normal time switch catalog. Up to 10 periods or exception 
days can be defined for each calendar. 
TSP function=Steps+Tmp: The time switch program determines both fan stage 
setpoint as well as the temperature setpoint (Comfort/Economy).
