Fan wont run on auto for what ever reason my brand new unit....wont run in auto....however the fan will come on if i use manual on for fan then lower the temp...it cools fine but fan runs full time....if i switch it to auto once its running the fan stops, and the unit just starts humming..when i installed the unit i didnt bother hooking up the furnace wires to the ac unit..figured id run two t-stats then trying to chase wires through the walls... any ideas as to why the unit wont work in with the fan on auto setting ??

Make sure your tstat is programmed for electric, not gas. Or in the settings you want that the TSTAT CONTROLS THE FAN.
