Units with dis play: Mus t be placed in a group addres s to dis play operation/symbol on the dis play.
These objects available only when PID control is enabled.
Units with dis play: Objects must be placed in a group address to display open window symbol on the display.

This is a setpoint set. It can be used to adjust all heating setpoints (Com fort, Precomfort and Eco)
This is a setpoint set. It can be used to adjust all cooling setpoints (Comfort, Precom fort and Eco)
The controller operating mode must be set to Auto to receive operating modes from a time switch over the bus. The
operating mode Auto remains until overwritten by another object (15 or 58).
Room operating mode is received over the bus.
(corres ponds to object 58 for units with display)
Room operating mode is provided to the bus.
Devices
Receives the occupancy state over the bus, e.g. from a presence detector.
The active heating setpoint can be read over the bus with object 23.
Note: The Precomfort setpoint is adjusted if the com fort setpoint, visible on the display (vis ible setpoint -3 K), is adjusted
below the Precomfort setpoint. The internal setpoints (Heating Comfort, Heating Precomfort, Heating Eco) can be adjusted
via bus using objects 160, 161 and 162, or using object set 12
The active cooling setpoint can be read over the bus with object 24.
Note: The Precomfort setpoint is adjusted if the com fort setpoint, visible on the display (vis ible setpoint +3 K), is adjusted
above the Precomfort setpoint. The internal setpoints (Cooling Comfort, Cooling Precomfort, Cooling Eco) can be adjusted
via bus using objects 163, 164 and 165, or using object set 13
The initial Economy heating setpoint is adjus ted via bus using this object.
These objects (160...165) mus t be activated in ETS:
