Q: WARNING: \"Meter inadequately tuned (CVRMSE Eng > 25.0; CVRMSE Dmd >35.0)\"
A: ASHRAE Guideline 14 says that the CVRMSE should be <25% for energy, and <35% for demand. The CVRMSE is almost the Root Mean Square of the deviations. It is roughly a measure of the average distance of the points from the fit line. Many see the CVRMSE as being more important than the R2 value.

Just as with the \"R2 < .75\" warning, there is no way to remedy this warning without tuning the meter properly.
