Works as it should - better install manual online
By Mark G. (from Philadelphia, PA) on 1/9/2014
Review for: Grundfos UP10-16BN5/ATLC Pump, 1/2" FPT, 115V, w/ IFC, Aquastat, Timer & Line Cord (97525921)
Works fine. I set it up to recirculate back to the cold water input to the hot water tank, instead of into the cold water pipe. The manual that came with it is all pictures. You don't really need a manual to install it, but the links from this web site take you to a manual with actual English descriptions. It would be nice if the temp setting would have actual degrees, instead of low and high.
Quiet, low wattage but no check value as advertised

Review for: Grundfos UP10-16BN5/ATLC Pump, 1/2" FPT, 115V, w/ IFC, Aquastat, Timer & Line Cord (97525921)
This product is advertised with a check value. I purchased and installed the item, when the green LED is not on (not circulating) the upstairs shower is running cold water. I closed the ball value to cut off the recirc line and the burner on the tankless heater turned on, indicating there's no check value.

I am trying to figure out the difference in Grundfos recirc pumps - UP10-16B5 ATLC and UP10-16BN5 ATLC. What feature or option does the "N" part number give or take away on these 2 pumps?
