I have an Airguide Home Confort Station. I have been using it with no problems until I dropped it and it switched from F to C on the temp side. I now cannot remember how to change it back to F , nor can I figure it out, Help?!

It may be a switch on the back ?

There is very small switch in the battery compartment. Take the cover off the battery compartment. The switch is in the top, right corner of the compartment. Use a small screwdriver or a kitchen knife to move the switch from C to F.
