Enabling of the function

The function can be centrally disabled or enabled.
Basic setting: the outside air damper is enabled.
The following S-mode communication object is used to integrate the damper enabling:
Enable dampers (Input communication object)
Flags Type
R W K T U
0 1 1 0 0 1.003
DPT_Enable
The following communication object is used in LTE-mode:
Enable dampers (Input)
Possible partner function blocks
115 HVACOpt
DisableDamper
HVAC-Optimizer
Geographical
zone
The use of the outside-air damper can only be implemented in conjunction with the
RXB21.1 controller. In this case, the AC 24 V 3-position damper actuator is connected
to the outputs Y3 and Y4.
8.6.3

Position values for damper actuators

The position of the outside air damper is mapped to the bus.
In S-mode, the following communication object is used for this purpose:
Outside air damper (Output communication object)
Flags Type
R W K T U
1 0 1 1 0 5.001
DPT_scaling
In LTE mode, the "position" of the outside air damper is transmitted as follows:
Outside air damper (Output )

Geographical zone
If the LTE bus information is not required, it can be disabled (see pages 90 and 143 for
notes on reducing the load on the bus).
