An environmental control system is disclosed for controlling the environment within a plurality of zones within a building with a plurality of heating, ventilating and air conditioning units. The environmental control system comprises a plurality of controllers for controlling the plurality of heating, ventilating and air conditioning units, respectively. Each of the plurality of controllers includes a temperature sensor connected to a thermostat control for controlling a heating, ventilating and air conditioning unit in accordance with an output from the temperature sensor. A link interconnects the plurality of controllers into a network. Each of the plurality of controllers may alter the operation of the thermostat control in accordance with the operation of the remaining plurality of controllers interconnected into the network. The environmental control system provides multiple modes of operation including a preferred first non-overlap mode for preventing the simultaneous actuation of multiple heating, ventilating and air conditioning units. A less preferred second overlap mode permits simultaneous actuation of multiple heating, ventilating and air conditioning units for only a limited time period and a least preferred third demand saver setback mode lessening the environment requirements to reduce the need to simultaneously actuate multiple heating, ventilating and air conditioning units.

Control system for multiple heating, ventilation and air conditioning units

An indoor environmental condition control and energy management system includes a plurality of inputs. A user input receives user input parameters including a desired indoor environmental condition range for at least one energy unit price point. An indoor environmental condition input receives a sensed indoor environmental condition. An energy price input receives a schedule of projected energy unit prices per time periods. A processor, coupled to the inputs, computes an environmental condition deadband range for multiple energy unit price points based on the user input parameters and controls at least one energy-consuming load device to maintain the indoor environmental condition within the computed deadband range for a then-current energy unit price point. In an embodiment, the environmental condition includes at least temperature and the at least one load device includes a heating and cooling system. The processor, in one embodiment, communicates through a communications link with at least one energy supply company and selects one energy supply company for a premise to minimize energy consumption cost.
