PLEASE LEAVE THIS MANUAL WITH THE HOMEOWNER
Thank you for purchasing the Aprilaire® Model 65 Humidifier Control. Your
control allows you to set the RH (Relative Humidity) level for your home and
will control your humidifier to maintain the setting. The control also
displays the RH.
The RH setting you choose will depend on your comfort level and the amount of
moisture your home can tolerate without causing condensation to form on
windows or other surfaces. As outdoor temperature drops, condensation is more
likely to occur on cold surfaces such as windows, and so the RH set point will
need to be adjusted accordingly. The control comes with a label you can apply
to the front that will serve as a reminder and a guideline for adjusting the
RH setting as outdoor temperature varies. The recommended settings, also shown
in TABLE 1 are based on years of research and apply to the average home.
If you have other devices that measure and display RH, they may not match the
display on the Model 65 control due to differences in calibration or the
location of the devices. The Model 65 control allows you to apply an offset to
the display so that it will match another device. Whether the actual RH is 32%
or 36% does not matter as long as you are comfortable.
SETTING AND OPERATING THE CONTROL – SEE FIGURES 1 & 2
Apply the RH setting label to the front cover if you want a guideline for
setting the control according to outdoor temperature. Since all houses are
different, you will need to determine exactly where to set the control so
that you have enough humidity to meet your needs, but not so much as to cause
excess condensation on windows or other cold surfaces.
**CAUTION**
Do not adjust humidity set-point above recommended level or to recommended
level if condensation occurs on inside surface of windows or on other
surfaces. Excess condensation can cause damage to structure or furnishings.
Excess moisture can also allow the possibility for mold growth to occur.

TURNING THE CONTROL ON & OFF
Begin by pressing the ON button. ON will appear on the display. This means the control is on, but it does not necessarily mean the humidifier is running. In order for the control to turn on your humidifier, several conditions must be met:
- The control and humidifier must be powered,
- the RH level in the conditioned space must be below the set point, and
- your furnace or furnace blower must be running.
When these conditions are met and the humidifier is operating, ON will blink
in the control display.
Note: If you have an Aprilaire Model 800 Steam Humidifier and a Model 850
Fan Pack, they will operate independently of any HVAC (Heating, Ventilating
and Air Conditioning) equipment. To disable the humidifier, press the OFF
button. The control will remain on and display OFF plus the actual RH, but
will not allow the humidifier to operate. The control must be ON in order to
adjust the RH setting.
SETTING THE DESIRED RH LEVEL
Use the and buttons to display and raise or lower the RH setting. When
pressing the and buttons, SET and the RH setting will be displayed. Each press
of the buttons will change the setting by 1% RH. If a button is pressed and
held, the setting will change 1% RH every 1/2 second. SET will disappear and
the display will once
again show the actual RH 5 seconds after the buttons are pressed.
TABLE 1 – OUTDOOR TEMPERATURE AND RECOMMENDED INDOOR RH SETTING
| Outdoor Temperature | Recommended Indoor RH Setting |
|---|---|
| +40°F | 45% |
| +30°F | 40% |
| +20°F | 35% |
| +10°F | 30% |
| 0°F | 25% |
| -10°F | 20% |
| -20°F | 15% |
OPERATING LIMITS
If the temperature in the space to be conditioned drops below 40°F or rises
above 99°F, the control will not allow the humidifier to operate. Under these
conditions, the display will blink ON and . Once the temperature is in the
normal operating range, the control will once again allow the humidifier to
operate and the blinking ON and
will no longer be displayed.
ADJUSTING THE RH DISPLAY OFFSET
If you have another device that displays RH in your home, it may not match the
Model 65 Control display due to placement or a difference in calibration. If
you want the devices to match, the RH displayed by the Model 65 control can be
adjusted higher or lower by up to five percentage points. Allow the control to
acclimate to the space for 48 hours before adjusting the offset. The control
must be on in order to adjust the offset. Press and hold the OFF button for 5
seconds or until the display shows a value between -5% and +5%. Use the and
buttons to adjust the offset. The control will revert back to the normal
display mode after 5 seconds.
CLEANING THE CONTROL
The outside surface of the control may be cleaned with cloth dampened with water or glass cleaner. Do not spray liquid onto the control. Do not use abrasive or solvent- based cleansers on the control. Damage to the control or RH sensor could result.
