Temperature PI control
Activate the control if you want to use it.
General control
Set, in which cases
setpoint values and extension time
received via object are to
be retained. The parameter is only taken into consideration if the setting via object is
activated below. Please note that the setting "After power supply restoration and pro-
gramming" should not be used for the initial start-up, as the factory settings are always
used until the 1st communication (setting via objects is ignored).
For an adequate regulation of the ambient temperature, comfort, standby, eco and
building protection modes may be used.
Comfort
when present,
Standby
during short absences,
Eco
as a night-time mode and
Frost/heat protection
(building protection) e. g. with the window open.
The settings for the temperature control include the setpoint temperatures for the in-
dividual modes. Objects are used to determine which mode is to be selected. A change
of mode may be triggered manually or automatically (e.g. by a timer, window contact).
The
mode
may be switched with two 8 bit objects of different priority. Objects
„... HVAC mode (Prio 2)“ for switching in everyday operation and
„... HVAC mode (Prio 1)“ for central switching with higher priority.
The objects are coded as follows:
0 = Auto
1 = Comfort
2 = Standby
3 = Eco
4 = Building Protection
Alternatively, you can use three objects, with one object switching between eco and
standby mode and the two others activating comfort mode and frost/heat protection
mode respectively. The comfort object blocks the eco/standby object, and the frost/
heat protection object has the highest priority. Objects
„... Mode (1: Eco, 0: Standby)“,
„... comfort activation mode" and
„... frost/heat protection activation mode"
