*
1-bit object to output the switching command value for additional cooling in two-level
operation. This object is only available in this way if the type of feedback control is
configured to "Switching 2-point feedback control".
* These objects are only visible if, with combined heating/cooling command value,
separate command value objects are also displayed.

Room temperature measurement

Basic principles
The controller detects the room temperatures using one or possibly two external KNX
temperature sensors (e.g. push-button sensors with temperature measurement).
Temperature detection is configured on the parameter page "Room temperature con-
troller -> RTCx - General -> Room temperature measurement". Depending on the
configuration, the 2-byte objects "Room temperature - Measured value 1" and option-
ally, the additional "Room temperature - Measured value 2", are enabled.
According to KNX DPT 9.001, the temperature values must be made available
to the controller in the format "°C".
When choosing the mounting location of the external temperature sensor, the follow-
ing points must be considered...
