Energy-saving occupancy-controlled heating ventilating and air-conditioning systems for timing and cycling energy within different rooms of buildings having central power units

An automated HVAC control system for saving energy dispensed from a common HVAC energy source as a function of locally designated operating control parameters established in a plurality of utility zones dispersed at different locations from the common energy source, comprising in combination:

• said plurality of utility zones being adapted for receiving HVAC energy from said energy source for attaining temperatures locally designated at respective ones of the utility zones,
• common HVAC energy distribution control means for dispensing HVAC energy to said plurality of utility zones in response to said locally designated operating control parameters, said common HVAC energy distribution control means including a means of reducing peak load capacity requirements of said HVAC control system,
• energy cycling means for producing in response to said common distribution controls means scheduled on-off energy cycles in respective ones of said utility zones responding to the locally designated control parameters established at the respective utility zones,
• communication linking means for communicating between different ones of said plurality of utility zones and the common control means,
• designating means for relaying to said control means from said utility zones through the communication linking means sets of local control parameters designating individual utility zone operating temperatures and timing cycles for controlling said energy cycling means, and
• programmed control means for said common distribution control means for coordinating HVAC energy off-on conditions to implement individual designated operating temperatures and timing cycles at the plurality of utility zones.
