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).
