Questions using flexwatt on a rack

[suzuki4life]

Dimmers only work if the room temps are absolutely stable. If they are not they don't work well.

what?
A dimmer regulates the tape to only receive a certain amount of power PERIOD. POWER = temp. If you set the dimmer properly, they work right. If you think you will use the dimmer as a thermostat, you are asking for troubles. The dimmer is used to keep the temp from running at max power. The thermostat should be used to keep the tape itself from continuously running. In a proper setup, the tape should be turning on an off many times an hour and not in a continuous "on" position.
