HVAC Equipment Controls & Components
HVAC equipment controls regulate specific components of the HVAC system. They allow users to manage the system setpoints and help ensure that equipment operates within safe ranges for pressure and temperature. Temperature controls regulate the temperature of a space by turning on and off heating and cooling systems. Heating controls connect to furnaces and provide monitoring and control over their functions. Humidity controls monitor the humidity of a room and trigger the HVAC system when their control point is reached. Air conditioning and refrigeration controls connect to fridges, freezers, and other chilling devices and provide ways to monitor and control their operation. HVAC relays and sequencers coordinate the operation of system components to ensure safe, efficient operation.
