Bus output for current setpoints

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

6.1.2

Bus output effective setoints

Upon integration in a building automation and control system, the effective setpoints
are mapped by the controller to the following communication objects based on the
Effective room operating mode :
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 deadband, the Effective setpoint is transmitted either
as heating or cooling setpoint, depending on whether the controller last was cooling or
heating.
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.
