7.5.1.9.1.1.3.4 Dependent Parameter
Activate temperature limitation
Options:
A controller limit temperature can be activated using this parameter. Using the limit temperature,
the controller's control value for this stage can be set to 0 on reaching a parameterized tempera-
ture. In this way, exceeding (heating) or dropping below (cooling) this temperature can be pre-
vented.
An example of the usage of the limit temperature is a cooling ceiling, where dropping below a spe-
cific temperature must be prevented to protect the material of the ceiling against excessive cooling.
• No: The limit temperature is deactivated.
• Yes: The limit temperature is activated. The following dependent parameters are also dis-
played.

7.5.1.9.1.1.3.4.1 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).

7.5.1.9.1.1.3.4.2 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.
