Easy to install on UP15 pump
Follow the written instructions and installation to the UP15 pump is straightforward. Suggestion to the installer is to solder the ends of the power cord (not included) if braided copper so as to be able to use the quick-connect posts easier.
A design suggestion for Grundfos is to add an optional beveled plate to install between the timer and pump for applications where the pump is close to a wall - mine is very near a wall in the water heater closet - with the angle/slant of the mounted timer, you almost need to use a mirror to set the timer. If there was an option to mount the timer flush and not at an angle, it would be easier to read/set.

Okay, but the base enclosure was different than the original
My original timer went out, and I ordered this as a replacement. The original housing was a rectangular enclosure. The new one was more of a sloped base.
I was able to make it work, but it wasn't as easy of a replacement as I would've liked

Exactly what we needed for our Grundfos Pump
This timer allows us to save energy by setting the timer for the times we need hot water in our home.

A must to add toYour pump
I followed the wiring diagram which was pretty simple and it works like a charm! Don't be intimidated by doing the job yourself it's most definitely possible.

Simple installation; easily programmed
Used to control time that recirculation sensors are active. Not much room left in the pump wiring compartment, so had to install another little box for connections. Wiring diagram is a bit tricky, but can be followed, with care. The timer is Intermatic, in a third-party housing.
