Hey guys, does anyone have the instructions to change the thermostat from CHI Company from cooling to heating? I think it is just a matter of swapping one of the wires to the open post, but I'm not sure.

For the record, the link on their website for the instructions no longer works.

It looks like it's just a matter of swapping the hot (black) over to the other lug. A continuity tester would be the easiest and safest way to tell. With the t-stat set all the way down, there should be continuity with the current hot lug to the hot (narrow prong) on the back. The unused lug should show an open connection with the hot prong. Set the t-stat to the highest setting and your readings should be reversed.

Cool, thanks!
