Note : The low limit is the temperature at which the controller shuts down the unit to prevent the coil
from freezing.

Occupancy bypass timer
1
Note : The occupied bypass timer is used for timed override applications when a building automation
system is not present or when the building automation system does not send the occupied (override)
request. The timed override timer is maintained in the unit controller. When the timed override is
applicable, the controller reports Occupied Bypass as its effective occupancy mode. (The actual
enumeration of nvoEffectOccup is OC_BYPASS during the override condition.)
