ABSTRACT:
A control unit can be in communication with a plurality of displaced duct sensors. Sensors can be placed in supply and return ducts of an HVAC-type fluid delivery system. The unit can communicate status information as well as sensor sensitivity or other parameter values, on a per sensor basis, to a remote accessory unit via a communication protocol. The units can communicate via a wired or wireless medium.
