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. To indicate occupied mode, the contact must be open. To indicate unoccupied mode, the contact must be
closed. If operating as a network Master, the Heatpump controller will then send the occupancy status to all known
slaves on his network. NOTE: This input can instead be used as a prof of fan input, depending on the software configura-
tion. Alternatively, occupancy can be supplied by the NC2000 network controller.

Proof of Fan

The C1050 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. NOTE: This input can instead be used as an
occupancy contact input, depending on the software configuration.
