Abstract:
1. A system for zoned temperature control comprising: a first zone thermostat to measure a temperature of a first zone; a second zone thermostat to measure a temperature of a second zone; a first ECRV configured to vent air from a duct into said first zone; a second ECRV configured to vent air from said duct into said second zone; and a central system; said central system configured to obtain a first setpoint temperature and a first current zone temperature from said first zone thermostat, to obtain a second setpoint temperature and a second current zone temperature from said second zone thermostat, and to compute a first vent opening amount for said first ECRV and a second vent opening amount for said second ECRV according to said first and second current zone temperatures, said first and second setpoint temperatures, an amount of available air from said duct, a temperature of air in said duct, and a priority of said first zone relative to said second zone.
