A monitoring and control system for a heating, ventilating and air conditioning (HVAC) unit which provides zone control in plural zones in which each zone includes a control thermostat that is interfaced with the monitoring system so that each zone thermostat controls the HVAC unit as well as a damper unit for that particular zone thereby enabling independent zonal control in a multiple zone system which uses a single zone HVAC unit. The monitor considers individual zone needs, damper positions, amount of demand in the zone, mode of the zone damper and other factors which affect the comfort of zone occupants and, in response to signals from the thermostats, decides how and when to control the HVAC unit so that, in effect, a single zone HVAC unit becomes a multiple zone system. The system is comprised of two or more computerized thermostats which control both the HVAC unit through the monitoring control and the air distribution system of each zone through the damper for each zone, creating a heating, cooling, variable air volume and variable temperature control system. The thermostats also operate under control of signals received from the monitor.
