7.5.1.6.1.1.2.4.1 Dependent Parameter
Limit temperature
Options:
The value set here specifies the limit temperature that is not allowed to be exceeded (heating) or
dropped below (cooling). If the temperature reaches this value, the control value is immediately set
to 0.
The value set here is compared with the value received via a group object or via one of the physi-
cal device inputs (depending on the option selected, in the Input for temperature limit sensor pa-
rameter).

7.5.1.6.1.1.2.4.2 Dependent Parameter
Limit temperature hysteresis
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.

7.5.1.6.1.1.2.4.3 Dependent Parameter
Input for temperature limit sensor
Options:
• Via group object: The temperature value is received via a dedicated group object. The depen-
dent Basic-stage heating limit temperature group object is enabled.
• Via physical device input x: The temperature value is acquired via a temperature sensor con-
nected (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 temper-
ature sensor for the measurement of the room temperature and for the measurement of the limit
temperature.
7.5.1.6.1.2 PI continuous (0...100 %), PI PWM (On/Off), PI continuous (0...100 %) for Fan Coil
The following parameters are enabled if the PI continuous (0...100 %), PI PWM (On/Off) or PI con-
tinuous (0...100 %) for Fan Coil option has been selected in the Basic-stage heating control value
type parameter.
