Herpstat power matching function

[Domepiece]

I have never used anything other than standard, Are you having temp swings? I would actully ask Dion at herpstat directly he always answers quickly.

Im not sure, its lowering power and staying about .5 degree F below what it is set at. Also the manual says that it can be beneficial to adjust the power matching function when using on an incubator to keep temps from swinging and it is taking a long time to heat up, almost 2 days. I was actually going to call him today but I forgot. Thanks
