HVAC presence mode (HvacPscMod11)
Overview
The application function "HVAC presence mode 11" (HvacPscMod11) handles the response of the HVAC components to a presence detector, based on the room operating mode.
Function
Input
Presence detector and ROpMod provided by internal connection.
Configuration
The response of the HVAC components to a presence detector (HvacPscMod) can be configured for each room operating mode.
The configuration supports the following values:
- None: The presence detector is ignored.
- Consider present: The AF reacts to a change from absent to present (does not make sense for HVAC).
- Consider absent: The AF reacts to a change from present to absent (does not make sense for HVAC).
- Cons.present & absent: The AF reacts to a change from absent to present and vice-versa.
Output
The response (HvacPscMod) is forwarded to AF HvacPltModxx (via internal connection).
A BACnet client can also monitor HvacPscMod.

Engineering and commissioning
- This AF is required if a presence detector is in the room and used for HVAC. It provides HvacPscMod to HvacPltModxx.
- The HVAC coordination AF reads the presence detector and provides it to HvacPltModxx.
