The house we moved into this year has an Air Energy 2 Model XE2550. It simply has a dial on the front that says warmer and cooler. On the front its says "How to operate" but everything below is worn off and not readable. The operation seems straight forward but I was wondering if anyone would no where I could find a manual. I tried google but to no avail. If not I settle for someone telling me how to run it to make sure I know what I'm doing.
