Technical Manual Glass Push Button II Smart BE-GT2xx.01
The temperature can be shifted in 4 different ways:
1 Bit temperature shift
With the 1-bit temperature shift the glass push button merely transmits the command 1 for a shift of
the setpoint upwards and a 0 for a shift of the setpoint downwards.
The following table shows the available communication objects:
Number Name
0 Push buttons 1/2 –
Setpoint shift
1 Push buttons 1/2 – State
actual temperature
2 Push buttons 1/2 – State
current setpoint
temperature
Table 63: Communication objects - Temperature shift via 1 bit
1 Byte temperature shift
With the 1-byte temperature shifting, the glass 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 glass push
button.
The following table shows the available communication objects:
Number Name
0 Push buttons 1/2 –
Setpoint shift
1 Push buttons 1/2 –
State actual temperature
2 Push buttons 1/2 –

Length Usage
1 Bit Sends the Setpoint shift
2 Byte Receiving an external temperature for the
display of the current temperature - is only
displayed if the parameter "Use internal
temperature value" is set to "not active"
2 Byte Receiving the current setpoint temperature of
the temperature controller; to display the

1 Byte Receives the current setpoint shift; has to be
connected to all 1 byte objects which send the
setpoint shift to the controller in order to
correctly evaluate the current status of the
setpoint shift
