Anden A77 Digital Dehumidifier Control for Indoor Cultivation and Grow Rooms

A77 Wall-Mounted Digital Dehumidifier Control with Wi-Fi Capability

The Anden A77 Digital Dehumidifier Control provides wall-mounted humidity monitoring and dehumidifier control for grow environments. The A77 connects directly to an Anden dehumidifier via a hardwired connection and displays the current relative humidity reading on a bold, easy-to-read digital display. A simple interface — on/off buttons and up/down arrows — allows the operator to monitor and adjust the RH setpoint without accessing the dehumidifier unit itself.

The A77 adds Wi-Fi capability for remote monitoring, allowing grow operators to check and adjust RH from outside the growing environment. It is compatible with Anden's wireless humidity sensor for monitoring RH at specific locations in the grow space. The A77 is an upgrade from the A76 (DH20076) with the addition of Wi-Fi connectivity.

Key Features & Benefits

• Wi-Fi Enabled — Remote RH monitoring and adjustment via Wi-Fi connection.
• Wall-Mounted — Installs on the wall at a convenient monitoring location, outside or inside the grow space.
• Hardwired to Dehumidifier — Direct wired connection to the Anden dehumidifier for reliable, responsive control.
• Bold Digital Display — High-contrast digital display shows measured RH at a glance from across the room.
• One-Touch Controls — Simple on/off and up/down arrow buttons for RH setpoint adjustment.
• Wireless Sensor Compatible — Works with Anden wireless humidity sensor for remote point measurement.

Who Should Use This Control

The Anden A77 is suited for grow operations where remote monitoring of humidity via Wi-Fi is beneficial — particularly for facilities with multiple rooms, operators who are not on-site continuously, or installations where the dehumidifier is in an inaccessible location. It replaces the A76 for operations that want Wi-Fi-enabled remote access.

A76 vs. A77 — What Changes with Wi-Fi

The Anden A76 (DH20076) and A77 are both wall-mounted digital dehumidifier controls that hardwire to Anden dehumidifiers and display RH via an onboard or remote sensor. The A77 adds Wi-Fi connectivity, allowing humidity readings and setpoint adjustments to be made from a smartphone or remote interface without physically accessing the control panel. For operations that do not require remote access, the A76 is a simpler solution. For multi-room facilities or remote management scenarios, the A77's Wi-Fi capability provides additional flexibility.

Frequently Asked Questions

Does the A77 connect wirelessly to the dehumidifier?

No. The A77 connects to the Anden dehumidifier via a hardwired connection. Wi-Fi is used for remote monitoring and control of the A77 itself from a phone or network interface.

What is the difference between the A76 and A77?

The Anden A77 adds Wi-Fi connectivity compared to the A76 (DH20076). Both are wall-mounted digital dehumidifier controls with hardwired dehumidifier connections.

Is the A77 compatible with all Anden dehumidifiers?

Yes. The A77 is compatible with all Anden industrial dehumidifier models.

What sensor does it use for RH measurement?

The A77 can use an onboard sensor at the control panel location, or a compatible Anden wireless humidity sensor for measurement at a different point in the grow space.
