Hi;
Will have to try that because I feel like I'm going to pull the 
thing off the wall before that switch moves.  Other than that, 
however, its a great unit.  Never needded sighted assistance with 
anything other than initial installation.  Does remind me to 
change my air filter more often than I'd like and it periodically 
insists that its time to go back for service but those are things 
you can get rid of with a key press.  richard
