The temperature can be shifted in 4 different ways:
1 Bit temperature shift
With the 1-bit temperature shift, the push-button sends a "1" for an upward shift of the setpoint and
a "0" for a downward shift of the setpoint.

1 Byte temperature shift
With the 1-byte temperature shifting, the Push-button sends a 1-byte value which is multiplied by
the step width set in the controller. In order for the display and the current setpoint value to be
synchronous, the step width and the limits of the setpoint shift have to be specified in the Push-
button.

1 Byte Reception of the current setpoint shift. Must be
connected to all 1-byte objects that send the
setpoint shift to the controller to be controlled in
order to correctly evaluate the current status of the
setpoint shift.
