I have a controller that i would sell as my unit died early in life and it was totally my fault but they said i had to buy a whole new unit as they was not willing to sell me the main controller board but a year later to my surprise i received a controller for the indoor unit today so if any one needs it i am willing to sell it as i called but they did not want me to send it back and told me to throw it away. I did offer to send it back but they wanted me to send it for free. Nope you screwed me now its my turn. So if anyone is interested i have one for sell for the ac/dc 24k heat pump
