A Service alarm is displayed on the thermostat controller
when the input is energized. Tie this input into the air conditioning

A Filter alarm is displayed. This alarm can be connected to
a differential pressure switch that monitors a filter.

occupancy sensor, or from a voltage-free contact.

used in conjunction with a local airflow sensor connected to the
