What is a Knob?

Knobs in HVAC Systems

In Heating, Ventilation, and Air Conditioning (HVAC) systems, knobs play a crucial role in controlling various functions such as thermostats, air handlers, and fan controls. By turning the knob, users can adjust settings for temperature, humidity, airflow, and other parameters that regulate indoor air quality, building temperature, and comfort levels. HVAC knobs typically consist of a simple on/off switch for the thermostat and additional options for adjusting fan speed or direction, as well as indicators to signal when the system is heating or cooling. By providing intuitive and hands-on control over HVAC systems, knobs enable users to fine-tune their indoor environment and make adjustments in real-time, ensuring optimal performance and comfort.
