Thank you for your purchase of the Aprilaire® Model 76 Dehumidifier Control. Your control allows you to set the relative humidity level for your home and provides control of the dehumidifier from a convenient living space location. The Model 76 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 Model 76 can also act as a remote control for your Aprilaire Model 1710A, 1750A, or 1770A

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 dehumidifier to operate for an extended period of time when first installed.

dehumidifier if it is located in an inconvenient or hard to access area. For example, when the dehumidifier is located in and dehumidifying a crawl space or a basement, the Model 76 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 dehumidifier.

The dryness level settings can be approximated to relative humidity (%RH) using Table 1.

Energy Savings Tip #1: To reduce dehumidifier run time, when using the Model 76 as an external control, adjust the setting to be as high as is comfortable and when using the Model 76 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 Model 76 as an external control, turn the dehumidifier control OFF when you open your windows, just as you would with air conditioning.

Energy Savings Tip #3: When using the Model 76 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.
