Bus output for current setpoints

The present setpoints can be integrated in the building automation and control system
via the following S-mode communication objects individually or as triplets :
Present Eco cooling setp (Output communication object)
Present Precomf cooling setp (Output communication object)
Present Comf cooling setp (Output communication object)
Present Comf heating setp (Output communication object)
Present Precomf heat setp (Output communication object)
Present Eco heating setp(Output communication object)

6.1.2

Bus output effective setpoints

For integration into a building automation and control system, the controller maps the
effective setpoints associated with the effective room operating mode to the following
communication object:
Effective setpoint (Output communication object)
Effective setpoint heating (Output communication object)
Effective setpoint cooling (Output communication object)

DPT_Value_Temp
If the room temperature is in the dead band, the Effective setpoint transmitted by the
controller is either the heating or the cooling setpoint, depending on the controller's last
activity.
6.1.3

Bus outputs LTE mode

In LTE-mode, the current and effective setpoints are not transmitted to the building
automation and control system.
