An external temperature measurement for room control may be practical for larger rooms
and/or floor heating.
12.35.23 Temperature reading - External actual temperature – Object no
Object name
External actual temperature
2-byte communication object for reading an external temperature value provided via the
KNX bus.
12.35.24 Temperature reading - External actual temperature 2 – Object no
Object name
External actual temperature 2 2 byte DPT 9.001
2-byte communication object for reading an additional external temperature value
provided via the KNX bus.
12.35.25 Alarm function – Dew point alarm - Object no
Object name
Dew point alarm
This protective mechanism is only active in the cooling mode. It remains in place until it
is cancelled by the value (0). When an alarm is active, manual operation of the controller
is block. This information is indicated by a corresponding symbol on the control unit.
This 1-bit communication object is used to place the controller in the dew point alarm
mode. This causes the current setpoint value to be set to the heat protection setpoint
value in order to keep the structure from being damage by dew.
12.35.26 Alarm function – Condensate water alarm - Object no
Object name
Condensate water alarm
Condensate water alarm
(master / slave)
Item 1: This protective mechanism is only active in the cooling mode. It remains in place

Item 2: This protective mechanism is only active in the cooling mode. It remains in place
until it is cancelled by the value (0). When an alarm is active, manual operation of the
controller is block. This information is indicated by a corresponding symbol on the device.
When the master/slave mode is active, the condensate water alarm
(master/slave) objects must be connected to the alarm transmitter.
