2 Byte temperature shift
With the 2-byte temperature shift, the central operating unit sends a 2-byte temperature value
which is added or subtracted from the set basic comfort value.
The central operating unit sends the shift by the set step width at each keystroke.
In order for the display and the current reference value to be synchronous, the limits of the setpoint
shift must be specified in the central operating unit and have to be set to the same values as in the
controller.
The following table shows the available communication objects:
