Description
2-byte object to output the actual temperature (room temperature) determined
by the controller and used for the room temperature control. Possible value
range: -99.9 °C to +99.9 °C / Measuring range of internal temperature sensor:
0 °C to +40 °C.
The temperature value is always output in the format "°C".

Description
2-byte object for coupling an external KNX room temperature sensor. Thus
cascading of multiple temperature sensors for room temperature
measurement. Possible range of values: -99.9 °C to +99.9 °C.
The temperature value must always be specified in the format "°C".

Description
2-byte object for external specification of the basic setpoint for relative setpoint
specification. Depending on the operating mode, the possible range of values
is limited by the configured frost protection and/or heat protection temperature.
The controller rounds the temperature values received via the object
depending on the configured interval of the basic setpoint shift (0.1 K or 0.5
K).
The temperature value must always be specified in the format "°C".

Description
2-byte object for external setting of a setpoint for absolute setpoint presetting.
Depending on the operating mode, the possible range of values is limited by
the configured frost protection and/or heat protection temperature. The
controller rounds the temperature values received via the object to 0.1 K.
The temperature value must always be specified in the format "°C".
The setpoint modified by the setpoint shift can be reported back to the bus via
the object by setting the "Transmit" flag.
1: Each communication object can be read out. For reading, the R-flag must be set.
