External sensors (from bus)
As “external sensors” are intended KNX-devices (or conventional sensors interfaced to the bus through KNX
devices) which send states or values to the room temperature controller via the bus. Enabling an external
sensor, without connecting the corresponding communication object, generates a permanent alarm on the
display and suspends the thermoregulation function.
The folder
External sensors (from bus)
includes the following parameters:
Room temperature
Antistratification temperature
Outdoor temperature
Air quality
Floor surface temperature
Flow temperature
Anticondensation
Window contact X (X = 1, 2)
Presence sensor X (X = 1, 2)
Card holder contact
Analog sensor timeout
Digital sensor timeout
The folder does not have any secondary folder.

Parameters and communication objects
Parameter name
Conditions
Values
Room temperature
disabled
/ enabled
It enables a bus temperature sensor. The measured value can be used to
calculate a weighted average value in combination with the temperature
sensor integrated into the device or a temperature sensor connected to a
device input.
Relative humidity
Internal sensors
Relative humidity
sensor = disabled
disabled
/ enabled
It enables a relative humidity bus sensor to be used alternatively to the sensor
integrated into the device.
Humidity C.O. dimension
Relative humidity = enabled
1 byte (DPT 5.001)
2 bytes (DPT 9.007)
Antistratification temperature
disabled
/ enabled
I
t
enables a temperature bus sensor to carry out the antistratification function.
Outdoor temperature
disabled
/ enabled
I
t
enables an outdoor temperature bus sensor to display the measured value
on the display. This is alternative to an outdoor temperature sensor connected
to a device input: the parameter appears only if the external temperature
sensor is disabled in the Inputs folder.
Air quality
disabled
/ enabled
I
t
enables an air quality bus sensor to display the measured value (CO
2
concentration) on the display.
Coil temperature
disabled
/ enabled
I
t
enables a bus sensor for measuring the conveying fluid temperature at the
coil for heat exchange. The acquisition of the value allows realizing the hot-
start function of a fan.
