Heating regulation for cheap skates.

[MarkS]

I was using in-line dimmer for UTH for a couple of months before investing in a nice VE-300. One suggestion I have for anyone using this (either slider or rotary) is to put down a piece of tape and marking for the dimmer setting.
This way if you happen to accidentally move the slider, or want to change the setting based on recent temp reading you can see where it should be.

Good point, you need to know at a glace where the dial is set. I'll generally mark mine up with a sharpie showing the off position, the full on position and some marks around the outside for reference. Like this.
