Blower Status Switch

The unit is equipped with a differential pressure airflow
switch to monitor the blower (see Figure 30). If the
blower is turned on and the switch doesn't open to
indicate there is differential pressure between the inlet
and outlet of the blower, an alarm will be generated.
For switch settings, see Figure 30.
