Great Controller
Great price. We replaced our old analog economizer controller with the W7220 to have direct control of mixed air temperature, outside air temp control, and low temp freeze protection. This is for a RTU that is used for a computer room with a large variation in heat load (0.5 to 5.0 tons, depending on load). We economize in winter due to the extremely low OA temps.
