Awesome responses thank you! And yes I did mix up the IO-101 operating voltage
with the CU200.
So because efficiency is important we’ll keep the CU200 in the system.

Ron,
Brian's advice is sound.
240 vac is fine for the pump and the CU 200. The SQ series is rated 90-300 v AC
and 30-300 v DC, although the pump is happiest at around 90 v and up. If the
CU200 is already in the system and paid for, keep it: the diagnostics are nice,
and the signal circuit is
Hi Jay,
You are correct about the CU-200. It has an operating voltage range of
30-300 VDC and 90-240 VAC.
However, the IO-101 transfer switch is another story, and I think that is
what Ron meant. Up until recently Grundfos was only importing the 120 VAC
version of the IO-101, but now you can get
Friends:
The IO101 will accept only 120 VAC into the auxiliary port. This is the
connector with the threads on the bottom of the unit. It has a label
indicating 120 VAC. This will cause some confusion. The CU200 will accept 240
VAC and it will allow you to use a float switch.
The IO101 wi
Hi Ron,
What you describe with using a pressure switch and pressure tank, and just
running the pump with 240 VAC, is fine. You don't need the CU-200 to do
any of that, if all you are doing is switching AC. The diagnostics is
nice, but probably not worth the cost in this kind of simple setup.

Hi Ron
Where did you read that the CU 200 is only good for 120vac. The manual I see
shows 240vac 50/60hz?

Hello water pumping Wrenches, I have a customer who has a Grundfos SQFlex 11
pump and he is getting connected to the grid. He will still have his battery
back up charged by PV and wants to look at the most efficient way to operate
the pump. It seems to me that neither the IO101 or the CU200 real

A diode is a diode. Get an electronics technician to identify the correct
part and source it.

Corey - yes, nearby lightning can zorch PV array diodes en masse, and not
always all the diodes at once. Provided they are accessible and not potted
in epoxy DigiKey can provide replacements. When the module manufacturer has
gone out of business, getting the precise specs can be impossible, but
