HVAC Controls and Thermostats

3,143 products
HVAC controls include valves, switches, and dampers to regulate temperature, humidity, energy, and pressure systems in commercial HVAC and refrigeration applications. Room thermostats control temperatures in residential or commercial applications. Temperature controls maintain a desired setpoint temperature for commercial or industrial HVAC and refrigeration equipment. Process thermostats control the temperatures of air, liquids, or gases in manufacturing, commercial food service, or industrial processes. Pneumatic thermostats and retrofit kits sense the air temperature and change the air pressure in the system to regulate the heating or cooling within a space. Control accessories including enthalpy sensors, universal resistor kits, and temperature sensors reduce energy costs and conserve resources. Pneumatic damper actuators use air to provide dependable, proportional control of dampers in either independent or sequence operations in heating and cooling applications.
