Wiring One Occupancy Sensor to Control
Multiple RCD Dampers
An Occupancy Sensor can control multiple RCD dampers using
the VP and GND terminals. Up to six RCD dampers can be con-
trolled by one OSL Occupancy Sensor. The MIN to MAX range of
the OSL corresponds to the range from the minimum flow position
to fully open.

IMPORTANT
Only the +5V terminal on one RCD damper is connected to the Occu-
pancy Sensor.
When using one transformer to power multiple motors, wire all 24 VAC
motor terminals to the same transformer terminal and all COM motor ter-
minals to the other transformer terminal. Damper Motors are rated 3.5VA
and 130 miliamps during operation; 2.25VA and 90 miliamps when idle.
