I've had the worst time with those CU200 controllers as well. The only
reason I use them at all
is for the float switch function. Many of our agricultural installations
have long wire runs
between the tank/float and the controller, so we really have no other
choice than to use
the CU200.
Out of the last 32 SQ Flex installations we've only had one bad pump and
thankfully, that
was an infant mortality case and covered under warranty. And yes,
customer service at
Grundfos is horrible. About as bad as their documentation!
Like many of you, I was burned horribly with the Regretta pump
line....many bad pumps
and even more bad controllers. I dropped them like a hot potato and have
used the Grundfos
SQ ever since. It's definitely not perfect but it's better than the old
versions of the Eta/ Regretta.
Like Allan said, it was a tough decision to drop that pump line because
I like Windy Dankoff and
wanted to support Dankoff Solar. His company had a heart when he was
running it and I really miss that
old fashioned quality customer service! I figure he was stuck in the
middle of the Eta debacle like I was,
so no hard feelings. We still love ya Windy!
I'm following this thread with great interest. If the Lorentz pump has
indeed improved, I want
to know all about it. Thanks for all the great info!

I'm aware of 2 CU-200 failures recently and I agree that Grundfos CS is about
as bad as it gets in our industry. A customer had 3 Grundfos failures in the
last 5 years all within 3 months of warranty expiration (of course!!), I did
not make those sales but when he learned of my inclusion of the warranty his
4th pump came from me. WHEN, I was installing Grundfos I always included the
extended warranty (takes it to 5 years) at my cost and stopped selling any of
their controllers and used off-the-shelf stuff for a fraction of the cost
instead.
Happy Earth Day!!
