Abstract

A thermostat providing modulated or analog control of valves or dampers of an air management system. This permits operating a single cooling or heating stage with partially open valves or dampers as needed, since one full stage that is either fully on or off may not be easy to manage for effective air management of a particular type of building, zone or facility. The thermostat may also provide non-modulated control of multi-stage cooling and heating systems. The thermostat may even be used to control a modulated system having more than one stage of cooling or heating.

Claims

1. A thermostat system comprising:

a configuring device; and

a plurality of thermostats for air management systems, respectively; and

wherein;

the configuring device may upload, store, modify and/or download one or more configurations of the plurality of thermostats; and

each configuration may be modified by changing;

parameter settings;

schedules of parameter settings; and

/or modulated controls for heating stages and cooling stages.

2. The system of claim 1, wherein each air management system may have a plurality of zones.

3. The system of claim 1, wherein the configuring device has various configurations that may be downloaded to the thermostats of the air management systems at different locations.

4. The system of claim 3, wherein the configuring device is a commercially available computer.

5. The system of claim 3, wherein the configuring device is a person digital assistant.

6. The system of claim 5, the personal digital assistant is selected from group of devices consisting of a Palm™

and the like.

7. A thermostat system comprising:

a configuring device; and

a plurality of thermostats, each thermostat having at least one configuration for an air management system; and

wherein the configuring device may upload one or more thermostat configurations and perform diagnostics on the configuration.

8. The thermostat system of claim 7, wherein the diagnostics performed by the configuring device include disabling delays of functions in the thermostat system.

9. The thermostat system of claim 7, wherein the diagnostics performed by the configuring device include overriding sensor inputs and set points of the thermostat system.

10. The thermostat system of claim 7, wherein the diagnostics performed by the configuring device include testing sensors of the thermostat system.

11. The thermostat system of claim 7, wherein the diagnostics performed by the configuring device include testing a cooling process and/or a heating process of the thermostat system.

12. A thermostat system comprising:

a plurality of thermostats, each thermostat comprising at least one configuration for an air management system; and

a sequencing system controller connected to the plurality of thermostats for controlling and staging the plurality of thermostats; and

a configuring device; and

wherein the configuring device may communicate with system sequencing controller, and the configuring device may upload one or more configurations of the system sequencing controller and/or at least one configuration of the plurality of thermostats, and execute diagnostics relative to the thermostat system.

13. The thermostat system of claim 12, wherein:

the thermostat system includes sensors, fan processes, cooling processes, and/or heating processes; and

the diagnostics are executed relative to one or more of the sensors, fan processes, cooling processes, and/or heating processes.

14. The thermostat system of claim 12, further comprising a modulated control for a simultaneous operation of a heating device and a cooling device for affecting humidity.

15. The thermostat system of claim 12, wherein the diagnostics include disabling delays of functions in the thermostat system.

16. The thermostat system of claim 12, wherein the diagnostics include overriding sensor inputs and set points of the thermostat system.
