Vent control relays are essential components for HVAC systems that control the flow of air in a building. These relays are used to turn on and off dampers, which adjust the flow of air in different parts of the building. By controlling the flow of air, vent control relays can help to regulate temperature, humidity, and air quality, providing a comfortable and healthy environment for building occupants. These relays come in a variety of sizes and configurations to suit different HVAC systems, and are designed to be reliable and long-lasting. Whether for commercial or residential use, vent control relays are an important part of any HVAC system.
