This group object is enabled if the parameter Setpoint specification and adjustment is set to Absolute and
Comfort heating setpoint = Comfort cooling setpoint is set to No in the Setpoint manager parameter window.
This group object is hidden in actuator mode.
This group object can directly influence and overwrite the stored setpoint for Comfort heating. The value re-
ceived via this group object is permanently stored and serves as the new Comfort heating setpoint. Manual
setpoint adjustment acts on this setpoint.
The value must lie in the valid value range of 10...40 °C. A value outside this range is limited to this range.
