You can configure one of the Analog Inputs to monitor a binary contact closure for proof
of airflow. This is currently a Status Only input and will not affect the operations of the
CVC if no proof of flow is detected.

If you require a generic type alarm indication on a contact closure, you can configure an
Analog Input for either a Normally Open or a Normally Closed contact. This alarm will
not affect the CVC operation but it will be reported at the ZoneView AZ computer screen
and can be used to generate alarm callouts if all the proper equipment is installed for
remote communications.

If you install Flush Mount Wall Sensors with the optional slide adjustment, you can affect
the current heating and cooling setpoints up or down by a programmable amount. This
can be as much as 5°F above or below the current setpoints or as little as 1°F. The
position of the slide is proportional so that if it is halfway up or down, you affect the
setpoints by half the amount you programmed. If the slide is all the way up or down you
create the maximum effect on the setpoints.

You can configure an Analog Input to monitor for a differential pressure contact closure
in the event the filters become clogged. This contact closure can generate an alarm callout
if desired and if the remote communications options have been installed.
