What is a Switch?
Switches in HVAC Systems
In Heating, Ventilation, and Air Conditioning (HVAC) systems, switches are devices that control the operation of various components within the building, including heating and cooling systems, fans, and thermostats. By activating or deactivating these components, switches enable users to manage temperature levels, schedule maintenance, and troubleshoot issues in real-time. In HVAC systems, switches typically consist of a control unit (such as a thermostat) connected to a relay or switching device that converts the high-voltage electrical signal from the grid into a low-voltage signal for individual control devices like thermostats, fans, and valves. This allows users to select their desired temperature setting, turn equipment on or off, or monitor system performance in real-time, ensuring optimal indoor air quality and efficient system operation.
