FAN-POWERED MIXING BOX ASSEMBLY ABSTRACT OF THE DISCLOSURE A fan-powered mixing box assembly through whichconditioned air is supplied to a plurality of zones iscontrolled by a programmable fan-box monitor. The as-sembly comprises a mixing box, a multi-speed fan and aheating element having several stages. The monitor re-ceives data from and transmits data to a plurality ofprogrammable zone thermostats each of which controls azone via a duct damper through which air enters the zone. The monitor receives data from duct temperature and ductair pressure sensors for use in controlling the fan andheating element. Also, the monitor is responsive tosignals representative of the real time for operating theassembly in setback modes when the various zones are notoccupied. The monitor modulates a master damper forcontrol of supply air.
