My (rather old) Day&Night Gas heater has a summer switch. I've never seen one of these before, and I don't have the owner's manual as I just bought the house and that seems to be the one manual the previous owner didn't leave behind. I don't want to mess with it as the system seems to be working fine, but I'm curious what it does. Thanks.

The summer switch just moves air for comfort

Thanks biggsie! So, it basically turns the fan on. I can do that at the thermostat as well, but I guess this gives me another option. I appreciate the response!
