Quest Honeywell HumidiPro Humidistat, 24V

External 24V Humidistat for Ceiling-Mounted Quest Units

A dehumidifier mounted on the ceiling puts its onboard controls out of easy reach, and this external humidistat solves that by giving you a separate control point wired back to the unit. It's built around the Honeywell HumidiPro design, connected to a compatible Quest dehumidifier through a simple 24 volt wired connection.

That low-voltage link lets you set and adjust humidity targets from wherever is most convenient, rather than climbing up to the dehumidifier itself every time a change is needed.

Key Features & Benefits

• 24-Volt Wired Connection — low-voltage wiring keeps installation simple.
• External Mounting — place the humidistat wherever it's easiest to access.
• Honeywell HumidiPro Design — familiar, straightforward humidistat controls.
• Suited to Overhead Installations — built to pair with ceiling-suspended Quest dehumidifiers.

Who Should Use This External Humidistat

Growers with a Quest dehumidifier mounted overhead who want to set and adjust humidity targets without reaching the unit directly.

It connects through a simple 24 volt wired connection between the humidistat and a compatible Quest dehumidifier. That low-voltage wiring keeps the installation straightforward.

Where should this be mounted?

Mount it wherever is most convenient and accessible, since it's designed to be installed away from the dehumidifier itself. That's especially useful for units suspended overhead.

What does the HumidiPro design offer?

It's built around Honeywell's HumidiPro humidistat controls, a familiar design for straightforward remote operation. Setting and adjusting humidity targets works the same way most Honeywell humidistats do.

Can this control more than one dehumidifier?

It's built to pair with a single compatible Quest dehumidifier. Check with your installer if you need to control multiple units from one location.
