This installation is used to dehumidify a

whole house and also a separate conditioned

space like a finished basement. Two dampers

are installed, one normally-closed damper

(6508) is installed in the branch leading from

the dehumidifier to the supply duct, and one

normally-open damper (6608) is installed in

the branch leading from the dehumidifier back

to the conditioned space. For convenience, a

basement kit (4522), which includes a

normally-closed damper (6508), a normally-open

damper (6608), and a 40VA, 24 VAC plug in

transformer (8027) can be ordered.

When the HVAC blower and the dehumidifier

are on, the dampers will energize and the

dehumidifier will operate in a whole-house

mode (Figure 4).

When the HVAC blower is off, the dampers

will be de-energized and the dehumidifier will

operate in a localized mode (Figure 5).

Note: The dampers will also be de-energized

when the dehumidifier is off preventing

backflow of air when only the HVAC blower

is on.

WHOLE-HOUSE, WITH LOCALIZED OPTION FOR CONDITIONED SPACE

In this configuration, the dehumidifier will automatically switch between whole-house dehumidification when the HVAC equipment

is on, and localized dehumidification when the HVAC equipment is off.
