Abstract
A heating, ventilation, and air conditioning (HVAC) system. The HVAC system includes a sensor that detects a temperature of a heater of a heating component and emits a signal indicative of the temperature. A flow management device controls a flow of electricity or fuel from a power source to the heating component. A controller receives the signal from the sensor and operates the flow management device to block the flow of electricity or fuel to the heating component when the signal is indicative of the temperature being above a set point.
Claims20
A controller of a heating, ventilation, and air conditioning (HVAC) system, wherein the controller is
- configured to:
- receive a signal indicative of an amount of airflow through a heating component of the HVAC system from a sensor of the HVAC system;
- compare the signal indicative of the amount of airflow to a threshold;
- and
- operate a flow management device to block a flow of electricity or fuel to the heating component based on comparison of the signal indicative of the amount of airflow to the threshold.
A heating, ventilation, and air conditioning (HVAC) system, comprising:
- a heating component configured to heat an airflow directed through the HVAC system;
- a sensor configured to detect an operating parameter of the airflow directed through the HVAC system and to emit a signal indicative of the operating parameter of the airflow;
- a switch or valve configured to limit a flow of electricity or fuel to the heating component;
- and
- a controller configured to:
- receive the signal indicative of the operating parameter of the airflow;
- compare the signal indicative of the operating parameter of the airflow to a threshold value;
- and
- actuate the switch or valve to limit the flow of the electricity or fuel to the heating component based on comparison of the signal indicative of the operating parameter of the airflow to the threshold value, wherein the operating parameter is an amount of the airflow directed through the HVAC system.
A controller for a heating, ventilation, and air conditioning (HVAC) system, wherein the controller is configured to perform operations comprising:
- receiving, via a sensor, a first signal indicative of a temperature of a heating component of a furnace system of the HVAC system, wherein the heating component is configured to heat an airflow;
- comparing the first signal indicative of the temperature an to a threshold value;
- and
- outputting a second signal to actuate a flow management device of the furnace system to block flow of electricity or fuel to the heating component of the furnace system based on comparison of the temperature to the threshold value.
