Principle of Operation
The purpose of the Healthy Climate
®
Whole Home Dehu-
midifier is to keep humidity in the home at acceptable lim-
its, thus reducing the unwanted effects of high humidity.
The dehumidifier gathers data from the HVAC system, or
from the space it is controlling, and measures the condition
of the home air to decide when to run. An integrated air
cycling feature can activate the HVAC blower to cycle air
through the home to balance the indoor conditions. The
dehumidifier can also operate an optional ventilation
damper to bring in outside air.

Operating Instruction
The Whole Home Dehumidifier has three adjustable set-
tings: the dryness setting, the air cycle period and the air
cycle time within that period. The dehumidifier dryness can
be set from ˆ1˜ or ˆLESS˜ to ˆ7˜ or ˆMORE˜ based on de-
sired comfort level. Most installations should be initially set
between ˆ3˜ and ˆ5˜ or ˆNORMAL˜ setting; however this
can be adjusted to your individual needs.
Air cycle period is set using the DIP switches, and the po-
tentiometer is used to set the air cycle time which are both
located on the control board under the knob and are set
during installation. If the cycle period is set to 1 hour and
the cycle time potentiometer is set to 20 minutes, you will
get 20 minutes of air cycling every hour. It is important to
understand that the air cycling requirement ˘ 20 minutes
per hour in this example ˘ may be satisfied by a heating,
cooling, or fan call initiated by your thermostat, or if such
calls do not satisfy the air cycling requirement, from a blow-
er call initiated by the dehumidifier itself.
Y2188 Whole Home Dehumidistat (optional)
If your Whole Home Dehumidifier has the optional dehu-
midistat installed, refer to the Whole Home Dehumidistat
Owner’s manual for operation information.
Adjusting Dehumidifier Main Control Set Point
Use the main control knob on the outside of the unit to set
the dehumidifier dryness setting. Start with a ˆNORMAL˜
setting for most installations. Moving the knob clockwise to
ˆMORE˜ will make conditions drier. Moving the knob to-
ward ˆLESS˜ allows for higher moisture levels.
