Controllers

HVAC controllers are used to regulate the operation of heating or air conditioning systems in a building, plant, or room.

HVAC control systems use sensing devices like thermostats, humidistats, and process controllers to compare the actual state of an environment with a predetermined setpoint. Controllers then turn on or turn off heaters, air conditioners, and fans to adjust the ambient temperature and humidity to match the target state.

HVAC controllers use a combination of analog and digital inputs and outputs to perform a variety of actions, including taking measurements, starting and stopping equipment, and opening or closing valves, dampers, and more.
