The Suburban Mfg 521212 is an OEM replacement control module designed for the Suburban IW60RL on-demand (tankless) water heater, also sold as part #5280A and part of Suburban's Advantage On Demand line with a built-in recirculation loop. This 12V DC board restores dependable ignition sequencing and operational control, providing consistent hot water performance when the original board fails.
This control module is designed specifically for the IW60RL (the recirculation loop version). It is a different part number from the standard IW60's module board (part #521135). Confirm the exact water heater model before ordering.
