HVAC Controllers: Pneumatic Controllers, Electronic Controllers

T775 Standalone ControllerHVAC Controllers gather information from sensing devices and then make a decision based upon that information. Utilizing HVAC controllers, we can energize contactors and relays, open and close valves and dampers, or even turn equipment on or off.

NECC designed the pages linked below to help you find the right HVAC controllers and accessories for your application. If you’re not sure what you need, call us at (800) 227-9800.
