Vectra S2 Low Flow Calibration - Anyone Successful Recently?

[SPS2020]

Hi All!

I'm having an issue with the Calibration process on my Vectra S2 pump. The same issue occurs whether using the Driver or the Mobius app. The first step turns off the pump. Next the pump is supposed to ramp down to a TRICKLE over the course of a couple of minutes. Mine never get close to a trickle. So the outcome of the Configuration setup is that the pump goes from a medium (~700 gph) to the full 1400 gph. I'm trying to set it low for a UV sterilizer. This is occurring on a one year old pump and driver and a brand new pump and driver.

Thanks for any insight!

@SPS2020 which method are you using to calibrate? I did my M2 via the Controller and didn’t have any issues. Only thing I’d say is that there was a bit of a lag between when I would turn the dial and seeing the flow slow down. So it probably took me a few min to get it to “minimum”

I tried using the driver and the Mobius app, but neither worked for me.

At what point are you turning the dial?

Bump for any S2 insight. I have to be doing something wrong.

+1 for can't get them to calibrate and gave up (2x L2's, 1x S2)

The closest I have gotten is to immediately click 'Done' on the first screen when it indicates that it is going to ramp down to a trickle (which never happens). In that manner, the pump will indicate it is drawing 2 watts when I set it to a constant 1%. However, that is still a few hundred gallons per hour.
