Occupancy Mode (Night Setback)

Dry Contact originating from an External Timer:

Temperature setback savings can be obtained by using a dry contact originating from an external timer
to switch the controller from occupied to unoccupied mode. The timer contact used must be connected
to the "OCC" and the "GND" terminals (see Figure 3). To indicate occupied mode, the contact must be
open. To indicate unoccupied mode, the contact must be closed. As a network Master, the Rooftop
controller will then send the occupancy status to all known slaves on his network.
