Abstract

Abstract Systems and methods are described for a usage monitoring HVAC control system. A method, includes: providing a usage monitoring heating ventilation and air conditioning control system, the usage monitoring heating ventilation and air conditioning control system including a programmable digital thermostat with an on board memory, issuing personal identification numbers to each of a plurality of system users; associating each of the plurality of system users with at least one of a plurality of user types; storing the personal identification numbers in a first data structure in the on board memory; and linking each one of a plurality of entries in the first data structure by reference to at least one of a plurality of entries in a second data structure in the on board memory, the second data structure including a list of user types. A method, includes regulating user access to an interactive user interface of a programmable thermostat, each user identified by a personal identification number associated with a user type such as, for example, building owners, maintenance personnel, building tenants, and manufacturers.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 188 words
A method, comprising: providing a usage monitoring heating ventilation and air conditioning control system including a programmable digital thermostat with an on board memory; issuing a plurality of personal identification numbers to a plurality of system users; storing a plurality of personal identification numbers in a first data structure in the on board memory; linking each one of the plurality of personal identification numbers in the first data structure by reference to at least one of a plurality of entries in a second data structure in the on board memory, the second data structure including a plurality of user types; receiving a request for an additional period of heating ventilation and air conditioning system services from a requesting system user; maintaining another data structure in the on board memory of the programmable thermostat, the another data structure including a list of time entries, each time entry associated with one of the plurality of system users; updating the another data structure by adding a duration in units of time to a time associated with the requesting system user; and uploading the another data structure to a central billing computer.
Claim 2
Independent Claim 188 words
A method, comprising: providing a usage monitoring heating ventilation and air conditioning control system including a programmable digital thermostat with an on board memory; issuing a plurality of personal identification numbers to a plurality of system users; storing a plurality of personal identification numbers in a first data structure in the on board memory; linking each one of the plurality of personal identification numbers in the first data structure by reference to at least one of a plurality of entries in a second data structure in the on board memory, the second data structure including a plurality of user types; receiving a request for an additional period of heating ventilation and air conditioning system services from a requesting system user; maintaining another data structure in the on board memory of the programmable thermostat, the another data structure including a list of time entries, each time entry associated with one of the plurality of system users; updating the another data structure by adding a duration in units of time to a time associated with the requesting system user; and uploading the another data structure to a central billing computer.
Claim 3
Dependent Claim 26 words
