6.9.3 Release room unit for time switching operating mode
If the individual room controller is equipped with a room unit QAX3x.x (with
operating mode setting or fan speed), it may occur that when specifying room
operating mode Economy using the user time switch, the room unit changes to
Comfort. The result is that the entire air handling unit switches for a single room.
This may further result in unallowed overpressure in the air ducts depending on the
sizing of the air system. The setting parameter "Comfort via room unit" is used to
prevent this.
Comfort via room unit
= Yes
Manual changeover from Economy to Comfort is
possible via QAX3x.x and QAW740
Comfort via room unit
= No
Manual changeover from Economy to Comfort is not
possible via QAX3x.x and QAW740
