Abstract

An autodiscovery system for configuration information about an HVAC system being provided to a controller or thermostat. Configurations or parameters may be autodiscovered from communicating equipment. Also, this equipment may be manually selected and set without affecting the autodiscovery status of the remaining equipment. There may also be non-communicating equipment that does not provide information to the thermostat. However, the thermostat may control the non-communicating equipment via an equipment interface module.

Claims

1. An autodiscovery system for an HVAC system comprising:

a controller; and

at least two communicating HVAC apparatus;

a first link of communication between the controller and each of the at least two communicating HVAC apparatus for communicating configuration information from each of the at least two communicating HVAC apparatus to the controller; and

a second link of communication between the controller and each of the at least two communicating HVAC apparatus for communicating control information from the controller to each of the at least two communicating HVAC apparatus; and

wherein;

the controller may autodiscover the at least two communicating HVAC apparatus;

at least one apparatus of the at least two communicating HVAC apparatus may be manually set while the remaining communicating apparatus may remain autodiscovered; and

the controller is a thermostat.

2. The system of claim 1, further comprising:

at least one non-communicating apparatus; and

wherein the controller provides parameter control information to the at least one non-communicating apparatus.

3. The system of claim 2, further comprising:

an equipment interface module having an input connected to an output of the controller and having an output connected to an input of the at least one non-communicating apparatus; and

wherein equipment control information to the at least one non-communicating apparatus is via the equipment interface module.

4. The system of claim 1, wherein an autodiscovery of a communicating apparatus is a providing of configuration information about the communicating apparatus to the controller.

5. The system of claim 4, wherein configuration information comprises one or more of the following:

apparatus model;

apparatus serial number;

heating cycle rate;

compressor stages;

cooling cycle rate;

apparatus existence;

blower pressure;

heating stages;

air purification specifications;

humidifier stages;

dehumidifier stages;

HVAC parameters;

zone descriptions; and

sensor information.

6. The system of claim 1, further comprising:

sensors; and

wherein some of the sensors are subject to autodiscovery.

7. The system of claim 6 wherein the sensors communicate parameters to the controller.

8. The system of claim 7, wherein the parameters comprise one or more of the following:

temperature;

humidity; and

pressure.

9. The system of claim 3, wherein:

the controller is remotely operated via telephonic, internet or wireless connections; and

remote operation comprises autodiscovery and manual inputs to and outputs from the controller.

10. The system of claim 7, wherein at the same time one or more parameters can be designated to be autodiscovered and one or more other parameters can be manually selected, set or entered.

11. The system of claim 1, wherein automatically discovered information can be overridden without affecting autodiscovery of other information.

12. An autodiscovery system for an HVAC system comprising:

a controller; and

at least one communicating HVAC apparatus;

at least one non-communicating HVAC apparatus;

a first link of communication between the controller and the at least one communicating HVAC apparatus for communicating configuration information;

a second link of communication between the controller and the at least one communicating HVAC apparatus for communicating control information;

an equipment interface module having an input connected to an output of the controller and having an output connected to an input of the at least one non-communicating apparatus for communicating control information between the controller and the non-communicating apparatus; and

wherein;

the controller may autodiscover one or more configuration information about the at least one communicating HVAC apparatus;

an autodiscovered parameter may be manually overridden without changing other autodiscovered parameters; and

the controller is a thermostat.
