Resideo R8222U1006/B DPST General Purpose Relay Normally Open 24V
The Resideo R8222U1006/B is a 24V DPST normally open general-purpose relay designed to control electrical circuits in HVAC systems. It operates by using a low-voltage signal to energize the coil, simultaneously closing both poles to allow current flow to connected components. Commonly used in furnaces, air handlers, and heating or cooling control systems, it ensures reliable switching performance.
