ABSTRACT:
A zoned heating and cooling system is controlled by a relay panel with a controlling thermostat in a first zone, and an additional thermostat in each additional zone. A relay corresponding to each first and additional zone, a relay to control the mode in which the system operates, and a fan relay, work in conjunction with the thermostats to: turn on system heating or cooling equipment; open dampers to provide conditioned air to those zones which call for heating or cooling; close dampers to block conditioned air from entering the zones which do not call for heating or cooling, when other zones do call; open all dampers when there is no calling; and provide for the manual or automatic control of a system fan.
