Abstract
An automated energy saving system dispenses HVAC energy from a common energy source to a set of utility zones, typically rooms in a house or commercial building which are dispersed at different locations remote from the energy source, typically a roof top unit. Each utility zone selects locally established operating conditions as operating parameters serviced at a control center, typically located at the energy source site, to distribute available HVAC energy to the independent utility zones of the set in an energy saving mode of operation. The remote utility zones communicate with the common controller by wiring or wireless communication links. At the energy source energy is distributed by off-on control of individual energy conduits to the individual utility sites. The control parameters at the local utility zones define energy-off periods by way of predetermined interactively set temperature ranges in one preferred automated delivery mode for delivering both heating and cooling energy from the HVAC energy source. Timing cycles for energy delivery during reduced energy delivery periods are also interactively defined at local utility sites for initiating automatic control function…
