This model includes a remote sensor so you can fine-tune humidity in a specific area, plus digital controls, programmable ventilation settings, a high-temp cutout, and real-time display of conditions—all in one sleek, compact unit.

If you're serious about creating or maintaining an ideal environment, this controller is a perfect match for your Quest dehumidifier.

Key Features

Remote Sensor for Localized Control
Target a specific part of your space to get accurate readings and precise response from your dehumidifier. Perfect for large or multi-zone environments.

Digital Humidity Set Point
Dial in your desired relative humidity—no guesswork. The digital interface lets you set exact RH levels for consistent conditions.

Programmable Ventilation Timer
Control a motorized damper and coordinate with your dehumidifier’s fan. Set it to run on a schedule, stay open, stay closed, or adjust as needed.

High Temperature Cutout
Protect your equipment and space. The system shuts down if your pre-set temp limit is exceeded, helping avoid damage from overheating or hot air intrusion.

Fan/Filter Operation Control
Run the fan only when needed, or set it to continuous mode for steady airflow. This helps with air circulation and filter life.

Easy-to-Read Display
The backlit screen shows you everything at a glance: time, day, temperature, and RH. All the important info, right on the wall.

Compact and Wall-Mounted
Measuring just 4.95" wide × 1.06" deep × 4.19" tall, it fits cleanly on your wall without taking up space or looking bulky.
