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.

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.
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.
When the control is first powered up, it will display “30%”, which is the default setting.
