Abstract

A method of performing method of performing a diagnostic testing procedure on a space-conditioning system, comprising running a triggering module. Running the triggering module includes reading a database of triggering rules in the triggering module of the space-conditioning system, checking the database to determine if any of the triggering rules are satisfied. Running the triggering module includes also includes setting an output state of the triggering module equal to true, if at least one of the triggering rules is satisfied, or, setting the output state of the triggering module equal to false, if none of the triggering rules are satisfied. Running the triggering module further includes communicating the output state to a diagnostic control module of the space-conditioning system.

Claims

1. A method of performing a diagnostic testing procedure on a space-conditioning system, comprising:

running a triggering module, including;

a) reading a database of triggering rules in the triggering module;

b) checking the database to determine if any of the triggering rules are satisfied;

c) setting an output state of the triggering module equal to true, if at least one of the triggering rules is satisfied, or, setting the output state of the triggering module equal to false, if none of the triggering rules are satisfied; and

d) communicating the output state to a diagnostic control module of the space-conditioning system.

2. The method of claim 1, wherein the database of triggering rules includes a first rule that achieves the satisfied value if:

the space-conditioning system has been in a quiescent state for N days continuously, the system currently in the quiescent state, and, a last diagnostic test was run N days ago, where N equals about 1 or more days.

3. The method of claim 1, wherein the database of triggering rules includes a second rule that achieves the satisfied value if:

any equipment component of the space-conditioning system has been in a quiescent state for N days continuously, the system currently in the quiescent state, and, a last diagnostic test was run N days ago where N equals about 1 or more days.

4. The method of claim 1, wherein the database of triggering rules includes a third rule that achieves the satisfied value if:

any equipment component of the space-conditioning system has been in a quiescent state for N days continuously, the system currently is in the quiescent state, and, a last diagnostic test was run N days ago.

5. The method of claim 1, wherein the database of triggering rules includes a fourth rule that achieves the satisfied value if:

a system component alert from the space condition system has been generated, the space conditioning system currently is in a quiescent state, and no diagnostic test has already been run after the occurrence of the system component alert.

6. The method of claim 1, wherein the database of triggering rules includes a fifth rule that achieves the satisfied value if:

an automated diagnostic testing procedure has been set to occur every X days, the space conditioning system is in a quiescent state, and a last diagnostic test was run X days ago, where X equals about 1 or more days.

7. The method of claim 1, wherein the database of triggering rules includes a sixth rule that achieves the satisfied value if:

a external signal has been sent to the triggering module to set the module'"'"'s state to equal true.

8. The method of claim 1, wherein the triggering module is configured to periodically run after a time period as defined by an end-user or a service technician of the space conditioning system.

9. The method of claim 1, wherein a timing subunit is configured to track time, to decide if the defined time period has expired or not expired, and to cause the triggering module to run if the defined time period has expired.

10. The method of claim 1, wherein the output state communicated in step (d) activates the diagnostic control module to perform the diagnostic testing procedure.

11. The method of claim 10, wherein the diagnostic testing procedure includes:

sequentially activating the space-conditioning system into each one of a series of different test operational system states;

recording diagnostic test scan results produced during the each of the test operational system states; and

analyzing each of the diagnostic test scan results to determine whether or not each of the test operational system states, and equipment components used in each of the test operational system states, are in an acceptable operational condition or an unacceptable operational condition.

12. The method of claim 11, wherein the acceptable operational condition is indicated by one of the diagnostic test scan result being one of:

an acceptable discrete state for an equipment component of the space conditioning system, an acceptable value for an operating parameter of an equipment component of the space conditioning system, or, a target performance indicator of the space conditioning system that is within an acceptable range.

13. The method of claim 11, further including the steps of:

e) communicating the operational conditions to a reporting module of the space-conditioning system;

f) analyzing the operational conditions to determine status indicators for the space condition system;

g) presenting at least a portion of the status indicators to a user interface.

14. The method of claim 13, wherein the portion of the status indicator communicated to the reporting module includes a listing of each of the diagnostic test scan results, and an acceptable discrete indicator, or, acceptable range indicator for each of the diagnostic test scan results.

15. The method of claim 13, wherein the portion of the analysis of the diagnostic test scan results communicated to the reporting module includes an indication of the acceptable condition having a borderline acceptable value.

16. The method of claim 13, wherein the user interface includes:

a first display output for an end-user of the system, first display output providing pass or fail indicators of the entire system, air-conditioning and furnace subunits of the system; and

a second display output for a service technician of the system, the second display output providing a listing of each of the diagnostic test scan results, and an acceptable discrete indicator, or, acceptable range for each of the diagnostic test scan results.

17. The method of claim 16, wherein the second display output is communicated to the service provide located in a location that is remote from the system via an electronic communication module.

18. A system for performing a programmed execution of a diagnostics testing procedure on a space conditioning system space, comprising:

a triggering module configured to trigger the programmed execution of the diagnostics testing procedure, including;

a memory medium configured to store a database of triggering rules;

a processing device configured to read and check the database of triggering rules to determine if any of the triggering rules are satisfied, and to set an output state of the triggering module equal to true, if at least one of the triggering rules is satisfied, or, setting the output state of the triggering module equal to false, if none of the triggering rules are satisfied; and

an output device configured to communicating the output state of the triggering module to a diagnostic control module.

19. The system of claim 18, wherein the triggering module further includes an input device configured to receive updates to the set of triggering rules.

20. The system of claim 18, further including:

the diagnostic control module configured to perform the diagnostic testing procedure; and

a reporting module configured to receive operational conditions results from the diagnostic control module, determine status indicators for the space condition system based on an analysis of the receive operational conditions results, and presenting at least a portion of the status indicators to a user interface.
