Airgenerate sent me a new t stat but it looks difficult to change out. My unit has the extra black wires on the back. I was hoping to be able to use the t stat on the storage tank. Anybody know how to bypass the t stat on the unit and use the extra wiring? I have a message in to Airgenerate but have not heard back yet.

Those 'extra wires' were discussed back a few pages..

It sounds like your built-in T-stat is shorted. Contacts welded together.
You will have to unplug it (one side will do) and connect those two
(extra) black wires to the T-stat in your heater tank.
To disarm this device, cut the black wire, between the T-stat and the screw-wire-connector..
Cap the cut wires, so they can't short to the chassis.
