Replacement Main Controller for RecPro Tankless Water Heaters
Electronics can only work for so long. And sometimes things just short out. Rather than replacing the entire tankless water heater, replace the controller board first. This main controller fits RecPro tankless water heaters (RP-1057) and makes for an easy replacement when things are on the fritz. Please note that the PCB is not protected against water so the main controller should be installed in an area that is protected from water.
