Universal accessory for timing and cycling heat, ventilation and air conditioning energy consumption and distribution systems
First Claim
1. A special purpose interactive programmable computerized accessory for controlling flow of thermal output from an adjunct thermal/ventilation system, comprising in combination,a thermal/ventilation system control computer, computer programming means for said computer for automatically controlling flow of thermal output from said thermal/ventilation system at programmed times to modify operation of said system, auxiliary interactively controlled programming means jointly operable with said computer programming means for establishing specified operation time control conditions in said computer, and output computer control means controlled by said computer programming means for automatically controlling the flow of thermal output from said thermal/ventilation system, wherein said auxiliary programming means comprises an interactive programming sub-system adapted to produce output signals for universally controlling pre-existing thermal/ventilation systems in response to interactively selected operating conditions.

Abstract
This invention provides a novel, inexpensive, universal energy control computing accessory module for altering at programmed times the operation of existing adjunct thermal/ventilation systems. In the module, interactive programming of control timing permits the accessory to be easily adapted for different types of adjunct installations to produce timed control signals particularly adapted for control of the particular installed system. One typical mode of operation is to turn on or off cyclically the thermal/ventilation system to run at a prescribed timing duty cycle. The invention may be used for diverse utility modes of operation, such as providing periodic ventilation controls for an unattended beach vacation home or for providing semi-automatic control of installed heating or air conditioning systems during occupancy of hotel rooms, dwellings, or stations within commercial buildings, as sensed by auxiliary detection means.
