Table 38: Example – Mode selection via 1 Bit
The mode selection via 1 byte is done via only one object, the DPT HVAC Mode 20.102 according to
the KNX specification. For mode selection, a hex value is sent to the " mode selection" object. The
object evaluates the received hex value and thus switches the associated operating mode on and
the previously active operating mode off. If all operating modes are switched off (hex value = 0), the
“Standby” operating mode is switched on.
The hex values for the individual operating modes can be taken from the following table:
Mode selection (HVAC Mode)
Hex-Value
Comfort
0x01
Standby
0x02
Night
0x03
Frost/Heat protection
0x04
Table 39: Hex values of HVAC Modes
The following example illustrates how the controller processes received hex values and thus
switches operating modes on or off. The table is based on each other from top to bottom.
Example (set priority: Frost/Comfort/Night/Standby):
Received Hex value

Table 40: Example – Mode selection via 1 Byte
The controller always reacts to the last value sent. If, for example, an operating mode was last
selected via a 1-bit command, the controller reacts to the switchover via 1 bit. If a hex value was
last sent via the 1-byte object, the controller reacts to the switchover via 1 byte.
Important: There is no priority between switching over 1bit and 1byte!
The communication objects for the operating mode switchover are as follows:
