Abstract

A control system is configured to improve the efficiency of the heating and/or cooling equipment, and to aid in cutting costs associated with the running of the heating and/or cooling equipment. That is, to save the user on utility costs, while maintaining comfort within the space that is controlled. It is another objective to facilitate advanced programming of the system as well as scheduling conflict resolution. The control system generally comprises a control unit 12 and a remote controller 14 (which may comprise a smartphone, a computer or the like).

Claims

1. A thermostat comprising:

a first communication connection, the first communication connection in communication with at least one condition sensor;

a second communication connection, the second communication connection in communication with a climate control system;

a user communication connection, the user communication connection configured to receive an input from a user requesting a change in operating parameters of the thermostat;

one or more processor units in communication with the first and second communication connections and the user communication connection; and

one or more computer-readable media comprising computer-executable instructions which when executed by the one or more processing units cause the thermostat to perform steps comprising;

receiving a communication from the user communication connection to reduce a cost of operating the climate control system;

receiving communication through the first communication connection pertaining to the at least one condition sensor;

determining at least one operating parameter of the climate control system to be changed to reduce the cost of operating the climate control system; and

communicating through the second communication connection with the climate control system to alter the at least one operating parameter of the climate control system to achieve a reduction in the cost of operating the climate control system.

2. The thermostat of claim 1 wherein the one or more computer-readable media further includes computer-executable instructions which when executed by the one or more processing units cause the thermostat to perform steps comprising:

receiving through the user communication connection at least a lower and an upper threshold of the at least one operating parameter of the climate control system;

wherein the step of determining an operating parameter of the climate control system to be changed further includes the step of confirming that the at least one operating parameter to be changed results in the at least one operating parameter being between the lower and upper threshold of the operating parameter.

3. The thermostat of claim 2 wherein the at least one operating parameter comprises at least one of temperature and humidity.

4. The thermostat of claim 2 wherein the step of receiving further includes the receiving of a lower and an upper threshold of the at least one operating parameter pertaining to a comfort range, and a lower and an upper threshold of the at least one operating parameter pertaining to a comfort margin.

5. The thermostat of claim 2 wherein the at least one operating parameter includes a plurality of operating parameters, with each of the operating parameters including a comfort range and a comfort margin, wherein the step of determining an operating parameter of the climate control system to be changed further includes the step of determining which of the plurality of operating parameters is to be changed to maintain the user closer to or within the comfort range.

6. The thermostat of claim 2 wherein the thermostat further includes:

data pertaining to operating cost of the climate control system; and

wherein the one or more computer-readable media further includes computer-executable instructions which when executed by the one or more processing units cause the thermostat to perform steps comprising;

determining the change in operating cost of the climate control system based upon the change in the at least one operating parameter;

providing to the user the determined change in operating cost.

7. The thermostat of claim 1 wherein the user communication connection is configured to receive a single communication in the form of a request to save from a user.

8. A thermostat comprising:

a first communication connection, the first communication connection in communication with at least one condition sensor;

a second communication connection, the second communication connection in communication with a climate control system;

a user communication connection, the user communication connection configured to receive an input from a user as to a timing schedule for the operation of the climate control system;

one or more processor units in communication with the first and second communication connections and the user communication connection; and

one or more computer-readable media comprising computer-executable instructions which when executed by the one or more processing units cause the thermostat to perform steps comprising;

receiving a timing schedule from a user;

determining if the timing schedule from the user conflicts with an existing timing schedule; and

performing a conflict resolution to determine an operating timing schedule based on the timing schedule from the user and the existing timing schedule.

9. The thermostat of claim 8 wherein the step of performing a conflict resolution further includes the step of utilizing the new timing schedule in place of the existing timing schedule where an overlap exists, and utilizing the existing timing schedule before and after the new timing schedule.

10. The thermostat of claim 8 wherein the step of performing a conflict resolution to determine an operating timing schedule based upon the timing schedule from the user and the existing timing schedule further is achieved without further input from a user, or requiring a change in the timing schedule submitted by the user prior to operation.

11. A method of operating a thermostat comprising the steps of:

receiving a communication from a user communication connection to reduce a cost of operating a climate control system;

receiving communication through a first communication connection pertaining to the at least one condition sensor;

determining at least one operating parameter of the climate control system to be changed to reduce the cost of operating the climate control system; and

communicating through a second communication connection with the climate control system to alter the at least one operating parameter of the climate control system to achieve a reduction in the cost of operating the climate control system;

receiving a timing schedule from a user;

determining if the timing schedule from the user conflicts with an existing timing schedule; and

performing a conflict resolution to determine an operating timing schedule based on the timing schedule from the user and the existing timing schedule.

12. The method of claim 11 wherein the method of operating a thermostat further comprises the steps of:
