SIC Industry Description

Industry: 3822—Automatic Controls for Regulating Residential and Commercial Environments and Appliances
Establishments primarily engaged in manufacturing temperature and related controls for heating and air-conditioning installations and refrigeration applications, which are electrically, electronically, or pneumatically actuated, and which measure and control variables such as temperature and humidity; and automatic regulators used as components of household appliances. Establishments primarily engaged in manufacturing industrial process controls are classified in Industry 3823; those manufacturing motor control switches are classified in Industry 3625; those manufacturing switches for household appliances are classified in Industry 3643; and those manufacturing appliance timers are classified in Industry 3873.
