Variable air volume terminal control systems and methods
First Claim
1. A method of controlling the temperature of a zone with airflow, the method comprising:
- storing, for use by a controller, a set of parameters that comprises a minimum airflow set point, a maximum airflow set point, a zone cooling temperature set point, and a zone heating temperature set point;
entering a first temperature control mode upon initialization of the controller, wherein the first temperature control mode modulates airflow to the zone between the maximum airflow set point and the minimum airflow set point to maintain the temperature of the zone between the zone cooling temperature set point and the zone heating temperature set point;
switching to a second temperature control mode upon the airflow reaching the maximum airflow set point and the temperature of the zone reaching the zone cooling temperature set point; and
switching to a third temperature control mode upon the airflow reaching the minimum airflow set point and the temperature of the zone reaching the zone heating temperature set point.

Abstract
A method and system of controlling the temperature of a zone with airflow. In one embodiment, the method includes entering a first temperature control mode that modulates airflow to the zone between a maximum airflow set point and a minimum airflow set point to maintain the temperature of the zone between a zone cooling temperature set point and a zone heating temperature set point. The method also includes switching to a second temperature control mode upon the airflow reaching the maximum airflow set point and the temperature of the zone reaching the zone cooling temperature set point; and switching to a third temperature control mode upon the airflow reaching the minimum airflow set point and the temperature of the zone reaching the zone heating temperature set point.

9. A temperature control system for a zone, the temperature control system comprising:
-
an airflow source configured to provide airflow to the zone;
an airflow measurement device configured to measure airflow to the zone;
a damper configured to control airflow to the zone;
a heating device configured to heat the airflow;
a thermostat device configured to measure the temperature of the zone; and
a controller configured to be in communication with the airflow measurement device, the damper, the heating device, and the thermostat, and to alter the airflow to the zone using at least one of the damper and the heating device based at least partially on the temperature of the zone and the airflow to the zone. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method of reconfiguring an existing temperature control system, the temperature control system having a controller and a first set of commands for controlling airflow to a zone, the method comprising:
-
accessing the controller;
deactivating at least a portion of the first set of commands; and
programming the controller with a second set of temperature control system commands, wherein the second set of temperature control system commands are configured to alter the airflow to the zone based on the temperature of the zone and the airflow being routed to the zone. - View Dependent Claims (16, 17, 18, 19, 20)
