[QUOTE=FINGAZZ;1568966]all you have to do is put a oulet strip that plugs right in the back to connect multi plugs to it.they all have a 700 watt output and if you do the math you could hook up alot of heat tape to it depends on the size but flex watt 11" is 20 watts per foot and the 4" is i think 4 watts.just know the watts alittle math and one unit can controle more then enough for rack systems.heres a some pics of the unit i bought.

You can get away with that but keep in mind with one temperature probe you are only monitoring one rack. If you are using different style or size racks or different heat tape on your racks the only rack that is going to regulate properly is the one that has the probe in it. You are not going to have a way to accurately control the others plugged in to it.
