WHOLE HOUSE / LOCALIZED CONVERTIBLE INSTALLATION AND OPERATION
In this configuration the dehumidifier will automatically switch between whole-house dehumidification when the HVAC
equipment is on, and localized dehumidification when the equipment is off. This installation is used to dehumidify a whole house
and a separate unconditioned space like an unfinished basement, or an area where circulation from that location throughout the
entire house is undesirable.
