Elkay A52399R Replacement Cartridge - Part

Howdy! Thanks for posting your question here on PlumbersStock concerning the Grundfos UP10-16 Recirculating Pump. This recirculating pump feature uses LED lights as indicators. If your boiler goes through its air proving and ignition phase, your Grundfos recirculating pump flashes/blinks orange/green. When it meets the flow temperature, then the light flashes/blinks green. If the indicator light goes red then turns off, then that means that you have a defective external temperature sensor but if it turns red and does not turn off, it means that you have a defective internal temperature sensor. You may check this Product Manual for more information about the auto adapt light. Should you have any further questions or concerns, please don’t hesitate to contact us.
