: The occupancy input applications vary for stand-alone and communicated instances. For more
information, see Table 32 on page 50.
Note
2
: The fan status device is normally closed during normal fan operation. When the fan is off
because of either a fan failure or the controller commanding the fan off, the binary input device opens.

Normally open When the controller commands the fan on and
the binary input remains open for one minute,
BIP is normal (diagnostic).
When the controller commands the fan on and
the binary input closes, BIP is active (no
diagnostic).
Defrost Defrost NA When input is Open, BIP is Active (Defrost
activated)
When input is Closed, BIP is Normal (no
