DescriptionThe Dry Contact Module features evaporator platinum fins, mode change, lock function and error monitoring. It connects to an outside power source.The Dry Contact Unit enables the indoor unit to be controlled and monitored by third-party controls by way of contact closure of 1 binary input and 2 binary outputs. The binary input is used to start/stop the indoor unit. The dry contact accepts a field supplied binary signal from a building automation system, timer, keycard switch, door/window switch, motion detector or similar occupancy condition sensor. The binary outputs provide two signals - one for indoor unit operation and the other for unit malfunction (error status). These outputs can be used for simple status monitoring or to enable external devices such as exhaust fans, outdoor air dampers/fans and lighting.
