Occupancy Binary Input

The binary input on the controller is used as an occupancy input if configured as SCC. For stand-
alone controllers (any unit not receiving a communicated occupancy request, typically from a
building automation system), the occupancy binary input determines the occupancy of the unit
based on the hardwired signal. Normally, the signal is hardwired to a binary switch or time clock.
For controllers that receive a communicated occupancy request from a building automation
system, the hardwired occupancy binary input is used with a communicated occupancy request to
place the controller in either occupied mode or occupied standby mode.
If neither the hardwired binary input nor a communicated request is used to select the occupancy
mode, the controller defaults to occupied mode.
