The Dry Contact Unit provides interface flexibility to the controls engineer for indoor unit operation.

A field supplied binary signal could be taken from a building automation system, timer, keycard switch, door switch, motion detector or any occupancy, or condition sensor. The Dry Contact Unit can also be used to start/stop other occupancy related devices such as exhaust fans, fresh air dampers and fans, economizers, or lighting.
