Parameters
7.4.1.3.1 —
Dependent parameter
Window open when
Options:
This parameter is used to select which object value is to be considered the window open status on
reception.
•
Object value = 0: On the reception of the object value 0, it is evaluated as the "Window open" status.
Reception of the object value 1 signifies "Window closed".
•
Object value = 1: On the reception of the object value 1, it is evaluated as the "Window open" status.
Reception of the object value 0 signifies "Window closed".
The controller reacts to the reception of the "Window open" status by changing to Building Protection mode
(building protection heating = frost protection, building protection cooling = protection against heat).
7.4.1.4 —
Dependent parameter
Dew point alarm input
This parameter is not visible if the Channel function parameter has been parameterized with the Actuator
channel option.
This parameter is not visible if the Basic-stage cooling parameter is deactivated.
Options:
This parameter is used to inform the integrated controller whether it is to include the dew point alarm
(Alarm/No alarm) in the control.
•
Deactivated: If Deactivated has been selected, the dew point alarm is not taken into account by the
controller.
•
Via physical device input: If this option is selected, the controller checks which of the physical device
inputs has been parameterized for a dew point sensor. The status of the dew point sensor connected
to this input is included in the control. The message: Configure in 'Inputs' parameter window appears.
Only device inputs that have been parameterized as a dew point sensor are detected as such.
If no input has been parameterized as a dew point sensor, the function is considered deactivated.
If several inputs have been parameterized as a dew point sensor, there is a logical OR link between
these inputs. As soon as one of the contacts signals the status "Dew point reached", the controller
evaluates the status as "Dew point alarm". Conversely, if none of the inputs signals the status "Dew point
reached", the controller evaluates the status as "No dew point alarm".
•
Via group object: The dew point alarm is received via a group object. The dependent Dew point alarm
group object appears. In addition, the dependent Dew point reached when parameter is enabled.
