3. Control On/Off (slave)
Output

If a 0 telegram is received, the controller switches to OFF mode and regulates the temperature to the setpoint value for frost/heat protection. When the con-
troller is switched on again, the remaining operating mode objects are queried in order to determine the new operating mode.
Note:
About item 2:
During active ON/OFF controller function in master/slave mode the ON/OFF (master) control object is to be linked with this object.
About item 3:
During active ON/OFF controller function in master/slave mode the ON/OFF (slave) control object is to be linked with this object.

Object function
Data type
6
1. Actual temperature
Output
2-byte floating point value
2. Actual temperature weighted
Output
2-byte floating point value
1. The object outputs the measured (room) temperature, adjusted by the calibration value.
2. The object outputs the temperature value which is calculated from the recording and weighting of internal and up to two external temperatures.
Note:
An external temperature measurement for room control may be practical for larger rooms and/or floor heating.

External actual temperature 2
Input
2-byte floating point value
2-byte communication object for reading an additional external temperature value provided via the KNX bus.

2. Fault, actual temperature (master)
Output
Switching
3. Fault, actual temperature (slave)
Output
Switching
If one of the parameterized input temperatures is unavailable to the controller for a period longer than the monitoring time, the controller enters the error
mode. The error mode is sent to the bus as the value 1.
Note:
About item 2:
This object must be connected to the "Fault, actual temperature (slave)" object in order to indicate the error mode.
About item 3:
This object must be connected to the "Fault, actual temperature (slave) object in order to indicate the error mode.
