2 Byte temperature shift
With the 2-byte temperature shift, the glass push button sends a 2-byte temperature value which is
added or subtracted from the set basic comfort value.
The Glass Push Button 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 have to be specified in the Glass Push Button and have to be set to the same values as in the
controller.
The following table shows the available communication objects:
