Method of controlling heating and cooling sources
First Claim
1. A method of controlling a plurality of heating sources comprising the steps of:
- (a) selecting a set temperature at which it is desired to maintain the indoor temperature;
(b) selecting an on temperature at which all heating sources will be turned on;
(c) selecting an add heat temperature;
(d) selecting an off temperature at which all heating sources which are not in a locked-on mode will be turned off;
(e) turning all heat sources on when the indoor temperature is below the on temperature;
(f) turning all heat sources off except a heat source which is in a proporational control mode and any heat source which is in a locked-on mode as the indoor temperature rises past the off temperature;
(g) transferring one of the heat sources from an off mode to a proportional control mode if the indoor temperature falls past the add heat temperature;
(h) proportionally controlling the heat source which is in the proportional control mode in order to try to maintain the indoor temperature adjacent the set temperature; and
(i) transferring the heat source which is in the proportional control mode to a locked-on mode in which the heat source is turned on and transferring another heat source from an off mode to the proportional control mode each time the indoor temperature falls past the add heat temperature until all heat sources are on the locked-on mode.

Abstract
A method of controlling heating and cooling sources utilizes a computer or an electronic thermostat to control a plurality of heating or cooling resources for regulating indoor temperature within a narrow temperature range. The method maintains a temperature within the control range by activating a required number of heating or cooling sources and proportionally controlling one of the sources within the control range. An additional heat source is activated each time the indoor temperature falls below a preset "add heat" temperature, and a heat source is deactivated each time the indoor temperature passes a preset "delete Heat" temperature. Similarly, when the method is operating in the cooling mode, an additional cooling source is activated when the indoor temperature passes an "add cooling" temperature, and an additional cooling source is deactivated each time the indoor temperature passes a "delete cooling" temperature.
