Sunbeamtech Chromatic Windmill Control Panel
@ 2005/08/03On the back of the Chromatic Windmill you will find all the connectors neatly lined up, and well labeled... You will also find a place to install a back-up battery. If the power is ever lost to the unit you won't lose your settings. This is a great feature, as I have always hated moving components around and losing the values that I had programmed in!
