OWNER’S MANUAL FOR HEALTHY CLIMATE®
DEHUMIDIFIER CONTROL MODEL Y6456
THIS MANUAL MUST BE LEFT WITH THE HOMEOWNER
FOR FUTURE REFERENCE
Installed as: EXTERNAL CONTROL or REMOTE CONTROL
Thank you for your purchase of the Y6456 Dehumidier Control. When used
as an external control, your control allows you to set the relative humidity
level for your home and provides control of the dehumidier from a convenient
living space location. The Y6456 uses an onboard sensor to monitor the relative
humidity in the space in which it is located and displays the measured relative
humidity on the digital display.
The Y6456 can also act as a remote control for your HCWHD3-070,
HCWHD3-095, or HCWHD3-130 dehumidier if it is located in an inconvenient
or hard to access area. For example, when the dehumidier is located in and
dehumidifying a crawl space or a basement, the Y6456 can be installed where
you spend most of your time, allowing you to make changes to the setting and to
see what the humidity is in these areas without having to access the dehumidier.

Setting the Desired Humidity Level
The control will allow you to set the desired humidity level in your home and
can be used to turn dehumidication On or Off.
The materials in a home act like a sponge, so the moisture in the materials
of your home is at the same level as the air. After drying the air, the materials
of the home will release moisture back into the air until they are again at the
same level. As a result, it is not uncommon for the dehumidier to operate for
an extended period of time when rst installed.
EXTERNAL CONTROL
Begin by pressing the ON button and ON will be displayed on the LCD Screen
(see LCD display in Figure 1). Use the arrow buttons to set the control at 55%
when rst installed. Allow the dehumidier to run for 24 hours before deciding
if you want to change the humidity setting.
Raise the setting if you prefer the air to be less dry; this will reduce the
amount of time that the dehumidier runs.
Lower the setting if you prefer the air to be more dry; this will increase
the amount of time that the dehumidier runs.
REMOTE CONTROL
Begin by pressing the ON button and ON will be displayed on the LCD Screen
(see LCD display in Figure 1). Use the arrow buttons to set the control to a
dryness level of 3 when rst installed. Allow the dehumidier to run for 24 hours
before deciding if you want to change the dryness level setting.
Increase the dryness level setting if you prefer the air to be more dry;
this will increase the amount of time that the dehumidier runs.
Decrease the dryness level setting if you prefer the air to be less dry;
this will reduce the amount of time that the dehumidier runs.
The dryness level settings can be approximated to relative humidity (%RH)
using Table 1.

Energy Savings Tip #1: To reduce dehumidier run time, when using
the Y6456 as an external control, adjust the setting to be as high as is
comfortable and when using the Y6456 as a remote control, adjust the
setting to be as low as is required for the space. If it feels clammy or “smells
damp”, change the setting to allow for drier conditions.
Energy Savings Tip #2: When using the Y6456 as an external control,
turn the dehumidier control OFF when you open your windows, just as
you would with air conditioning.
Energy Savings Tip #3: When using the Y6456 as an external control,
and if vacating your home for an extended period in the summer, set the RH
at 59% and set your thermostat to as high as you are comfortable setting
it in the cooling mode. Consult with appropriate professionals regarding
the highest temperature that is safe for your pets or possessions. This will
keep the humidity at a controlled level to help prevent mold while minimizing
the amount of cooling energy used.

CHANGING THE HUMIDITY OR
DRYNESS LEVEL SETTING
• The rst press of either the or
button will display the humidity
or dryness level setting on the LCD.
• Each subsequent push of the up
or down buttons will change the
setting by 1% or 1 dryness level.
• If a button is held down, the setting
will continually change by 1% or 1
dryness level every 1/2 second for
as long as the button is pressed.
• The control will exit the setting
screen 5 seconds after the last
button press/release. 90-1637

How Does the Control Work?
EXTERNAL CONTROL
• When the measured humidity is greater than the setting, the control will turn
on the dehumidier and ON will blink on the LCD display.
• When the measured humidity falls 3% below the setting, the control will turn
off the dehumidier and ON will stop blinking.
REMOTE CONTROL
• The control sends the dryness level to the dehumidier.
• Once per Cycle Period (set by your installer in the dehumidifier), the
dehumidier will sample the air in the area served by the dehumidier.
• If the dew point of the incoming air is above the dryness level, the dehumidier
will turn on and ON will blink on the LCD display.
• When the dew point of the incoming air falls below the setting, the dehumidier
will turn off and ON will stop blinking.
Control Limits
The control limits are used to make sure the dehumidier does not run when
conditions are outside of the operating limits. Dehumidiers are not as effective
when conditions are outside of the operating limits. For example, the dehumidier
will not remove much moisture when conditions are cool and dry. Control limits
allow the dehumidier to work efciently within the operating range and turn off
when conditions are outside of these limits.
• Dew Point Lower Limit: 40°F External Control
• Temperature High Limit: 99°F External Control
104°F Remote Control
• Temperature Low Limit: 50°F Remote Control
EXTERNAL CONTROL – SEQUENCE OF OPERATION
• The dehumidier will turn off if one of the control limits has been exceeded.
• If the control measures a dew point below 40°F OR a temperature above 99°F,
the control will deactivate the dehumidier output if actively dehumidifying,
the dehumidier will stop dehumidifying, and ON and *will blink on the
LCD screen (see Figure 2).
• The control will resume normal operation when conditions fall back within
the control limits.
REMOTE CONTROL – SEQUENCE OF OPERATION
• The dehumidier will turn off if one of the control limits has been exceeded.
• If the dehumidier measures a temperature below 50°F or above 105°F, the
dehumidier will stop dehumidifying.
• The control will resume normal operation when conditions in the remote
space fall back within the dehumidier control limits.
Cleaning the Control
The surface of the Y6456 Dehumidier Control can be cleaned with water or
a non-abrasive household cleaner, including glass cleaner. Do not spray any
liquid directly onto the control. Spray water or a cleaner onto a soft cloth and
gently wipe the surface of the control.
