Dependent parameter
Input for temperature limit sensor
Options:
The hysteresis on the limit temperature specifies the value by which the limit temperature must be dropped
below again (heating) or exceeded (cooling) before the controller becomes active again.
•
Via group object: The temperature value is received via a dedicated group object. The dependent
Additional-stage cooling limit temperature group object is enabled.
•
Via physical device input x: The temperature value is acquired via a temperature sensor connected
(to the selected input).
A temperature sensor must be actually connected to the temperature input selected and the input for the
sensor must have been correctly parameterized, otherwise the limit temperature function does not work.
If one of the device inputs is selected here as the input for the limit temperature, this input is no longer
used to acquire the room temperature. It is therefore not possible to use the same temperature sensor
for the measurement of the room temperature and for the measurement of the limit temperature.
