Abstract
According to one embodiment, a system includes a first and second cooling system, an automation controller, one or more sensors, and a hardware controller separate from the automation controller. The hardware controller processes various temperature set points in conjunction with a timer and configures the activation or deactivation of the first and second cooling systems accordingly.
Claims9
A system comprising:
- a first cooling system configured to cool a first portion of a space;
- a second cooling system configured to cool a second portion of the space;
- an automation controller configured to provide a first temperature set point;
- sensors configured to detect a temperature of the space;
- and
- a first hardware controller separate from the automation controller, the first hardware controller configured to:
- receive a second temperature set point that is provided by a user;
- determine a temperature difference between the first temperature set point and the second temperature set point;
- determine whether the temperature difference is less than a maximum temperature change limit;
- determine whether the second temperature set point is lower than the detected temperature of the space;
- determine whether the second temperature set point overrides the first temperature set point based on a determination that the temperature difference is less than the maximum temperature change limit;
- start a timer configured to expire after a set period of time in response to determining that the second temperature set point overrides the first temperature set point and that the second temperature set point is lower than the detected temperature of the space;
- in response to determining that the second temperature set point overrides the first temperature set point and to determining that the second temperature set point is lower than the detected temperature of the space, activate the first cooling system when the first temperature set point is above the detected temperature of the space and before the timer expires;
- deactivate the first cooling system when the timer expires;
- and
- in response to determining that the first cooling system should be activated, communicate a signal to the automation controller, the automation controller further configured to activate the second cooling system in response to receiving the signal.

A climate control system controller comprising a hardware processor configured to:
- receive a first temperature set point at which a first climate control system is to activate, a temperature of a space, and a second temperature set point;
- determine a temperature difference between the first temperature set point and the second temperature set point;
- determine whether the temperature difference is less than a maximum temperature change limit;
- compare the second temperature set point with the received temperature of the space to determine whether the second temperature set point is below the received temperature of the space;
- determine whether the second temperature set point overrides the first temperature set point based on a determination that the temperature difference is less than the maximum temperature change limit;
- start a timer configured to expire after a set period of time in response to determining that the second temperature set point overrides the first temperature set point and that the second temperature set point is lower than the temperature of the space;
- in response to determining that the first climate control system should be activated, communicate a signal to an automation controller separate from the hardware processor, wherein the signal triggers the automation controller to activate a second climate control system;
- in response to determining that the second temperature set point overrides the first temperature set point and to determining that the second temperature set point is lower than the temperature of the space, activate the first climate control system when the received temperature of the space is below the first temperature set point and before the timer expires;
- and
- deactivate the first climate control system when the timer expires.

A method comprising:
- receiving, by a processor, a first temperature set point at which a first climate control system is to activate from an automation controller that is separate from the processor, a temperature of a space, and a second temperature set point;
- determining, by the processor, a temperature difference between the first temperature set point and the second temperature set point;
- determining, by the processor, that the temperature difference is less than a maximum temperature change limit;
- comparing, by the processor, the second temperature set point with the temperature of the space to determine that the second temperature set point is lower than the temperature of the space;
- determining, by the processor, that the second temperature set point overrides the first temperature set point based on the determination that the temperature difference is less than the maximum temperature change limit;
- starting, by the processor, a timer configured to expire after a set period of time in response to determining that the second temperature set point overrides the first temperature set point and that the second temperature set point is lower than the temperature of the space;
- in response to determining that the second temperature set point overrides the first temperature set point and to determining that the second temperature set point is lower than the temperature of the space, activating, by a switch, the first climate control system when the first temperature set point is above the temperature of the space and before the timer expires to cool a first portion of the space;
- deactivating, by the processor, the first climate control system when the timer expires;
- in response to determining that the first climate control system should be activated, communicating, by the processor, a signal to the automation controller that is separate from the processor;
- and
- activating, by the automation controller that is separate from the processor, a second climate control system—in response to receiving the signal, wherein activating the second climate control system triggers the second climate control system to cool a second portion of the space.
