The extension time can be configured.
Units with display: Must be placed in a group address to display operation/symbol on the display.
These objects available only when PID control is enabled.
Units with display: Objects must be placed in a group address to display open window symbol on the display.
(corresponds to object 55 for units with display)
(corresponds to object 56 for units with display)
This is a setpoint set. It can be used to adjust all heating setpoints (Comfort, Precomfort and Eco)
This is a setpoint set. It can be used to adjust all cooling setpoints (Comfort, Precomfort 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.
(corresponds 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 comfort setpoint, visible on the display (visible 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 comfort setpoint, visible on the display (visible se3 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 adjusted via bus using this object.
These objects (160...165) must be activated in ETS:
Room temperature control --> "Room temperature setpoints as communication objects"
