Sensor
Determines which sensor will be used for room
temperature measurement.
Internal sensor: built-in sensor of the controller
External sensor: an external sensor coupled via
the bus, e.g. for severe measuring conditions
(swimming pools or similar).
Internal and external sensor: Both sensors are
used, for example, in large rooms.
Determines the weighting of the measured
temperature value for the internal and external
sensors.
That results in an overall value which will be
used for the further evaluation of the room
temperature.
Only if "Temperature detection" = "internal and
external sensor"
Determines the value by which the internal
sensor's room temperature value is calibrated.
Only if "Temperature detection" = "internal
sensor" or "internal and external sensor".
Determines the value by which the external
sensor's room temperature value is calibrated.
Only if "Temperature detection" = "external
sensor" or "internal and external sensor".
Determines the interrogation interval for the
external sensor's temperature value .
0" = sensor transmits its temperature value
automatically.
Only if "Temperature detection" = "external
sensor" or "internal and external sensor".
Determines the size of the value change of the
room temperature after which the current values
are automatically transmitted to the bus via
"Actual temperature" object 23.
Determines whether or when the determined
room temperature is to be cyclically output via
"Actual temperature" object 23.
