Window contact
Selecting
Window contact
uses the input to connect a floating contact that monitors the open/
closed state of the window. Selecting
Window contact
,
Via physical device input
on the
Application
parameters
page takes the status of this input into account in room temperature control. Without
this setting, the input value is sent on the bus but not taken into account in the controller.
Note
If several inputs are set to this option and the controller runs an evaluation, all inputs are inter-
nally linked by an OR operation. This means that as long as one of the contacts is open, the con-
troller responds as if all of the inputs are open, and only evaluates the window as closed once all
contacts signal a closed state.
Note
Inputs are scanned after a bus voltage recovery, download or ETS reset. Their current status is
sent on the bus when the sending and switching delay is complete.
