Abstract

A thermostat system having multiple and individual schedules. For instance, a user may have different schedules and setpoints for heating and cooling. An appropriate schedule combining individual schedules may be automatically selected based on a system configuration. Schedule control may involve manual changeover from one schedule to another or automatic changeover relative to the schedule combining schedules. The thermostat system may be programmable. Also, there may be a system switch mode, for example, between heat and cool, where the schedules of either may be edited. Scheduling may be menu and option key driven.

Claims

1. A controller system comprising:

a heat schedule;

a cool schedule;

an automatic changeover;

an automatic only changeover; and

a manual changeover; and

wherein for a manual changeover either the heat or cool schedule is automatically selected from the heat and cool schedule group for the controller system based on whether the manual changeover is set to heat or cool, respectively,

wherein when the automatic only changeover is selected, the controller system cannot be turned off.

2. The system of claim 1, wherein:

the heat schedule comprises a plurality of heat temperature setpoints;

the cooling schedule comprises a plurality of cool temperature setpoints;

each heat temperature setpoint has an associated heat time setpoint; and

each cool temperature setpoint has an associated cool time setpoint.

3. The system of claim 1, wherein the heat schedule and the cool schedule may be edited with the controller system disconnected from another system that the controller system is to control.

4. The system of claim 2, wherein each time setpoint is a beginning of a time period and an end of previous period if preceded by the previous time period.

5. The system of claim 2, further comprising:

a heat/cool schedule; and

wherein the heat/cool schedule is a combining of the plurality of heat setpoints and the plurality of cool setpoints.

6. The system of claim 5, wherein the automatic changeover is a selection of the heat/cool schedule for the controller system in lieu of a heating schedule or a cooling schedule.

7. The system of claim 5, wherein the heat/cool schedule may be edited with the controller system disconnected from another system that is to be controlled by the controller system.

8. A method for programming a controller system comprising:

loading a heat schedule into the controller system;

loading a cool schedule into the controller system;

selecting one of the heat and cool schedules for the controller system to implement; and

editing the selected heat or cool schedule, wherein a user is prevented from editing a non-selected heat or cool schedule.

9. The method of claim 8, wherein selecting one of the heat and cool schedules is a manual changeover configuration.

10. The method of claim 9, further comprising:

combining the heat schedule and the cool schedule in to a heat/cool schedule;

wherein selecting the heat/cool schedule is an auto changeover configuration, wherein when the auto changeover configuration is selected, a user is prevented from turning off the controller system.

11. The method of claim 10, further comprising:

editing the heat schedule and/or cool schedule; and

wherein the editing of the heat schedule and/or the cool schedule may be performed on the controller system with the controller system disconnected from another system to be controlled by the controller system.
