Window contact

Select the Window contact option to use the input to connect a floating contact that monitors the
open/closed state of the window. Select the Via physical device input option in the Window contact
parameter on the Application parameters page to take 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.
If several inputs are set to this option and the controller runs an evaluation, all inputs are internally linked
by an OR operation. This means that as long as one of the contacts is open, the controller responds as
if all of the inputs are open. Once all contacts signal are signaling the state window closed, the controller
evaluates this as window closed.
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.
