HVAC controller with dynamic temperature compensation
First Claim
Patent Images
1. A controller for operating HVAC equipment on a premise, the controller having:
- a processor operable to run an environmental control program, the environmental control program being operable to control the HVAC equipment;
volatile and non-volatile memory; and
an environmental sensor operable to provide a measured temperature value to the environmental control program for use in operating the HVAC equipment; and
wherein the processor is further operable to run a dynamic temperature control program that is operable to provide a dynamic correction factor to the environmental control program that dynamically compensates the measured temperature value relative to a premise temperature to create a corrected indoor temperature value, the dynamic correction factor being a function of a power consumption value determined by the controller.

Abstract
A controller is provided for operating HVAC equipment using an environmental control program. The controller has an environmental sensor operable to provide a measured temperature value to the environmental control program. The controller further runs a dynamic temperature control program that is operable to provide a dynamic correction factor to the environmental control program that dynamically compensates the measured temperature value for waste heat generated by power consumption within the controller.

10. A method for measuring temperature in a controller on a premise, the controller having an internal environmental sensor, the method comprising:
-
receiving a measured temperature value from the environmental sensor; applying a dynamic correction factor to the measured temperature value to determine a corrected indoor temperature value which compensates for waste heat within the controller; and providing the corrected indoor temperature value to an environmental control program running on the controller, the environmental control program being operable to control HVAC equipment on the premise; and wherein the dynamic correction factor is determined by calculating a power consumption value within the controller, the dynamic correction factor being a function of the power consumption value within the controller. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A dynamic control program for compensating for waste heat measured in a controller, the dynamic control program being stored in a non-volatile memory storage on the controller and operable to run on a processor of the controller located on a premise, the controller having an internal environmental sensor, comprising:
-
the program receiving a measured temperature value from the environmental sensor; the program applying a dynamic correction factor to the measured temperature value to determine a corrected indoor temperature value which compensates for waste heat within the controller; and the program providing the corrected indoor temperature value to an environmental control program running on the controller, the environmental control program being operable to control HVAC equipment on the premise; and wherein the dynamic correction factor is determined by calculating a power consumption value within the controller, the dynamic correction factor being a function of the power consumption value within the controller. - View Dependent Claims (20)
