Abstract
A fan-powered mixing box assembly through which conditioned air is supplied to a plurality of zones is controlled by a programmable fan-box monitor. The assembly comprises a mixing box, a multi-speed fan and a heating element having several stages. The monitor receives data from and transmits data to a plurality of programmable zone thermostats each of which controls a zone via a duct damper through which air enters the zone. The monitor receives data from duct temperature and duct air pressure sensors for use in controlling the fan and heating element. Also, the monitor is responsive to signals representative of the real time for operating the assembly in setback modes when the various zones are not occupied. The monitor modulates a master damper for control of supply air.
