My Ranco has a pretty fat cord. If you wire your own, I'd look into that and I'd avoid using a cheap extension cord.
Definitely use a heavy gauge cord on induction motor type equipment that has a heavy start current (dehumidifiers, fridges, freezers, etc.). In Nova Scotia it is electrical code that fridges need to be on their own circuit because they draw such a heavy amperage on start-up.
As far as the controller, as long it has a sensible deadband, you should be OK. You don't want the thing coming on every 5 min for 15 min.
