Sorry, I think I did the ramp test with the supplied power supply. The 12V 2A transformer started at 20V and declined to 12.23 and stabilized by the end of the 90 second cycle. The power output of that transformer was 12.4 V so it looks like the OpenSprinkler is doing what it is supposed to.

So you think running the DC pump at the higher initial voltage should be okay? I’m guessing if its a DC motor it will just spin a little faster initially? I can switch the leads on the pump so it’s not a big deal, but is the reverse polarity output the normal operation for the unit?

Thanks for the help.
