Water-saving models come equipped with an electronic humidistat and outdoor temperature reset to protect the home from condensation problems that can arise when the outdoor air temperatures fall. Fan-powered models are compatible with any type furnace system/single stage, variable speed and modulating. An exterior-mounted LED displays fault codes and provides visual indication when evaporative pad replacement is necessary.

It can operate as a stand-alone or complement all types of heating equipment and is fully compatible with heat pump systems. The CB707 can operate with 120- or 240-V input power.
