STAGED HEATING AND COOLING SYSTEM
First Claim
Patent Images
1. A staged control system for a heating and cooling system comprising in combination:
- adjustable heating means;
a plurality of first actuating means connected to actuate said heating means, each of said first actuating means being adjustable to provide a varying degree of actuation of said heating means;
adjustable cooling means;
a plurality of second actuating means connected to said cooling means, each of said second actuating means being adjustable to provide a varying degree of actuation of said cooling means;
adjustable refrigeration means;
a plurality of thiRd actuating means connected to said refrigeration means, each of said third actuating means being adjustable to provide a varying degree of actuation of said refrigeration means;
timed counting means connected to said first, second, and third actuating means operable to activate each of said plurality of actuating means independently and successively; and
temperature sensing means connected to cause said counting means to count and activate toward cooler actuating means in response to temperatures above a predetermined level and toward warmer actuating means in response to temperatures below the predetermined level.

Abstract
A control system for a heating and cooling system in which the amount of heating and the amount of cooling are both controlled in timed incremental stages by means of a signal from an up-down electronic counter which operates to call for the next successive stage at timed intervals in accordance with an electronic clock.

- adjustable heating means;
-
2. The apparatus of claim 1 in which said timed counting means comprises an up-down counter coupled with a clock means so as to count and switch actuating means at a predetermined rate.
-
3. The apparatus of claim 2 in which said temperature sensing means comprises a thermostat connected to said counter through electronic gates which are controlled also by said clock means.
-
4. The apparatus of claim 3 including means to monitor the count on said counter and means to speed up the clock means rate.
-
5. The apparatus of claim 4 in which at least some of said actuating means include adjustable resistances.
-
6. The apparatus of claim 4 in which at least some of said actuating means include triac gates.
-
7. The apparatus of claim 5 in which at least some of said actuating means include triac gates.
-
8. The apparatus of claim 7 in which said counter comprises a binary up-down counter in conjunction with decoding logic, said decoding logic having a plurality of separate outputs connected to activate each of said first, second, and third actuating means.
