Omron LY2-AC220/240 Relay Freon or undersized ductwork causing heatThe Omron LY2 AC220 240 is a heavy duty DPDT general purpose relay designed for reliable switching in HVACR control circuits and industrial automation. Engineered for high cycle performance, this dual pole double throw relay handles up to 10A resistive loads at 240VAC, making it a staple for managing compressors, fan motors, and auxiliary heating elements. The coil is optimized for 220 240Vac control voltage, providing stable actuation despite minor
