Parameters
—
Dependent parameter
Send control value cyclically (0 = cyclical sending disabled)
This parameter is only visible on the selection of the PI continuous (0...100%) option.
Options:
This parameter is used to specify the cycle time with which the control value is to be sent.
On the selection of the value 0, cyclic sending is deactivated.
—
Dependent parameter
Activate temperature limitation
Options:
A controller temperature limitation can be activated using this parameter. Using the temperature limitation,
the controller's control value for this stage can be set to 0 on reaching a parameterized temperature.
In this way, exceeding (heating) or dropping below (cooling) this temperature can be prevented.
An example of the usage of the temperature limitation is floor heating, where exceeding a specific
temperature must be prevented to protect the material of the floor.
•
no: The temperature limitation is deactivated.
•
yes: The temperature limitation is activated. The following dependent parameters are also displayed.

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 physical device
inputs (depending on the option selected, in the Input for temperature limit sensor parameter).
