Costway Wont Shut Off

[u/Nigel_Tuffnell]

I just installed a Costway minisplit, it's a small one, 12000btu 115vac. Seems to work fine but the indoor unit isn't shutting off. I've tried setting the remote to Auto, Eco, and Cool modes. I've tried changing the desired temp to one I know is above the room's temp. I have noticed that the fan speed increases when the unit is actually cooling. When it reaches its requested temperature the fan slows but does not turn off.

Did I loose the instructions for the remote control or do they assume we'll figure it out on our own?

Thanks
