Gain digital control of your Quest or Santa Fe dehumidifier with the Honeywell HumidiPRO. This humidistat can be installed on a wall or onto your HVAC unit's return duct to receive the best results.

Compatibility

The HumidiPRO works with both Quest and Santa Fe dehumidifiers, so one control covers either brand. That includes whole-home and ventilating models like the Santa Fe Compact70 and Ultra70. If you're running a Quest unit, it wires in the same way, no brand-specific control needed.

Installing Variations

Based on how you install the HumidiPRO, the control will operate accordingly. For a more precise reading, it is highly recommended to install the Honeywell HumidiPRO on a wall on the return side of the home's HVAC duct. Another option is to install the controller on a wall that is away from windows, bathrooms, and doors.

How to Work It

It doesn't get easier than this. With the HumidiPRO's easy-to-operate system, all you have to do is select a preprogrammed setting and you're all set.

• Dehumidification: Simply use the controls to set your desired maximum humidity level.
• Automatic Mode: The controller receives a reading from the included outside sensor and automatically sets the right humidity level to prevent window condensation.
• Manual Mode: Set the desired humidity level, and the unit will maintain it until you make a change.

Keep your Santa Fe Compact70 running clean with this MERV-13 Filter 4-Pack, plus a matching pre-filter. Together they trap a wide range of airborne particles, dust, and debris, so your unit works less and your air stays healthier.
