Should I be able to select P10 on the R2 (not pro) ?
Whenever I select this setting from the control pad on the roaster, it momentarily switches to P10, then changes to P9.
UPDATE: today, after updating my firmware to v106, I was able to select P10.
I have no idea if that is why, but for now things seem good.
It happens if your voltage is too low and the current becomes too high.
Newer firmware will switch into a constant current mode but the power could drop if your voltage is too low. So check your outlet and make sure to limit other equipment on the same breaker.
OK, thanks for the info.
I was using a different outlet than usual, so I suspect that may be what happened!
