Occupancy Mode (Night Setback)

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 8). 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.

Proof of Fan

The C1000 has a digital input that can be used to receive the proof of fan signal. Please refer to Figure 9
to see how to correctly connect it. To indicate proof of fan, the contact must be closed.
