<html> Hi Roger, I can't help you with your problem, but we have a similar problem at two local colleges. Almost all of the teacher's studios have only one outlet. That means that there usually is a computer, printer, desk lamp, fan/space heater, and possibly a room humidifier/dehumidifier plugged into the power strip. That is before the Dampp-Chaser systems get plugged in. Wish I could help.

The bottom line is that the fire marshal has requested that multiple dehumidifiers connect to the Humidistat via a "power strip", rather than a series of Add-An-Outlets or a three way adaptor. I thought this would be easy but my search and that of our purchasing agent have only turned up power strips with a grounded plug. Our Humidistat won't accept the ground pin. Has anyone ran into this before and found a solution? Any help would be greatly appreciated. Thanks, Roger</blockquote> </html>
