Dew point sensor

Select the Dew point alarm option to use the input to connect a floating contact that monitors the dew
point. Select the Via physical device input option has been selected in the Dew point alarm 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 no dew point alarm, the controller evaluates this as no
dew point alarm.
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.
