Anden A77 Digital Dehumidifier Control for Indoor Cultivation and Grow Rooms

Wall-Mounted RH Control Built for Indoor Cultivation Rooms

Checking humidity at a glance matters more in an active grow room than it does in most mechanical spaces, since growers are already walking the room daily and want a fast read without digging for a display. The Anden A77 is a wall-mounted digital dehumidifier control designed around that daily-check use case.

The A77 wires directly to the dehumidifier and puts a bold, easy-to-read RH display along with simple one-touch on/off and up/down arrow controls on the wall. It also supports Anden's wireless humidity sensor, so the control can read humidity from a separate sensor placed at canopy level instead of relying only on a sensor near the dehumidifier itself.

Key Features & Benefits

• Wall-Mounted Format — Puts the RH display and controls at eye level in the grow room, not just at the dehumidifier.
• Wired Connection to the Dehumidifier — Hardwires to the unit for a reliable, interference-free link.
• One-Touch On/Off — Simple on/off and up/down arrow buttons keep day-to-day adjustments quick.
• Bold Digital RH Display — Large, easy-to-read display for fast humidity checks during a walkthrough.
• Wireless Humidity Sensor Compatible — Works with Anden's wireless humidity sensor for canopy-level readings separate from the unit.

Who Should Use This Control

The A77 fits licensed cultivators and serious home growers who check humidity often enough during the day that a wall-mounted, at-a-glance display is worth the installation over relying on the dehumidifier's own panel. It's a good match for rooms where the dehumidifier itself sits out of easy view.

Wired Control with Wireless Sensor Support

The A77's connection to the dehumidifier itself is wired, not wireless — that link carries the control signal and doesn't depend on radio range or interference. Where wireless comes in is the optional Anden humidity sensor, which the A77 can read from independently of any sensor near the dehumidifier, letting growers place the sensor at canopy level for a more representative humidity reading.

Frequently Asked Questions

Is the A77 a wireless control?

No, the A77 connects to the dehumidifier with a wired connection rather than communicating wirelessly. It does support Anden's optional wireless humidity sensor, which is a separate accessory used to read humidity from a location apart from the dehumidifier itself.

Where should I mount this control?

Mount the A77 on a wall at eye level somewhere growers pass regularly, since its bold display and one-touch buttons are designed for quick daily checks. Keep wiring runs in mind, since it wires directly to the dehumidifier.

How do the one-touch controls work?

The A77 uses a single on/off button along with up and down arrows to adjust the humidity setpoint. That simple layout keeps routine adjustments fast without navigating a menu.

What is the wireless humidity sensor used for?

Anden's wireless humidity sensor is an optional accessory that lets the A77 read relative humidity from a different location than the dehumidifier itself — canopy level, for example. That's useful because humidity at plant level doesn't always match humidity right at the dehumidifier's intake.

How does the A77 compare to the universal A76 control?

Both hardwire to the dehumidifier and display relative humidity digitally, but the A77 is built as a wall-mounted panel with one-touch buttons and wireless sensor support, while the A76 is a simpler universal remote display and setpoint control. Choose based on whether you want wireless sensor support and a wall-mount form factor.
