Anden Digital Dehumidifier Control A76 — For A200V1, A300V1 & A300V3 Dehumidifiers

Wall-Mounted Digital Humidity Control for Anden A200V1, A300V1 & A300V3 — Precise, Simple, Hardwired

Effective humidity management in a cultivation environment requires a control interface that operators can read, set, and trust — one that maintains the target setpoint precisely enough to keep Vapor Pressure Deficit in range without constant manual adjustment. The Anden Digital Dehumidifier Control A76 provides exactly that: a wall-mounted hardwired controller that connects directly to compatible Anden dehumidifiers, displays current relative humidity clearly, and activates the dehumidifier only when humidity rises above the setpoint — reducing unnecessary run time and energy consumption.

The A76 operates on 24VAC power with a control range of 35-80% relative humidity and ±5% accuracy. A 3% differential setting prevents short-cycling — the unit activates when humidity rises more than 3% above setpoint and shuts off when it drops back below, rather than toggling on and off at the exact setpoint threshold. Low and high limit controls (40°F dew point low, 99°F high) add safety boundaries that prevent operation outside acceptable conditions. The 5-year warranty matches the warranty coverage of the compatible Anden dehumidifier units it controls.

Key Features & Benefits

• Precise Digital Humidity Control at 35-80% RH — Covers the full humidity range relevant to cultivation environments, from low-humidity early vegetative settings to the higher moisture conditions of propagation and cloning spaces.
• ±5% Accuracy with 3% Differential — Maintains humidity within ±5% of the target setpoint with a built-in 3% differential that prevents short-cycling and reduces unnecessary compressor starts on the connected dehumidifier.
• Wall-Mounted Hardwired Design — Installs at eye level in a convenient, accessible location — independent of the dehumidifier's physical position — allowing operators to monitor and adjust humidity without accessing the dehumidifier directly.
• Energy-Efficient Operation — Activates the dehumidifier only when humidity exceeds the setpoint, preventing the dehumidifier from running when conditions are already within range and reducing operating hours and energy consumption.
• 24VAC Low-Voltage Power — Operates on standard 24VAC control voltage, compatible with the Anden dehumidifier's integrated control wiring without requiring a separate power supply.
• 5-Year Warranty — Matches the warranty coverage of compatible Anden dehumidifier units for consistent long-term product support across the full control system.

Who Should Use the Anden A76 Controller

The A76 is required for Anden A200V1, A300V1, and A300V3 operators who need wall-mounted remote humidity control — enabling setpoint management from a convenient eye-level location rather than from the dehumidifier unit itself. It is appropriate for any installation where the dehumidifier is mounted in an overhead, mechanical room, or otherwise inconvenient access location, and for operators who want precise, dedicated humidity control with automatic dehumidifier activation.

Frequently Asked Questions

What is the difference between the A76 and A77 controllers?

The A76 is compatible with Anden A200V1, A300V1, and A300V3 dehumidifiers. The A77 is compatible with Anden A210V1, A320V1, and A320V3 dehumidifiers. The two controllers share the same specifications and form factor — the only difference is the compatible model designation. Always verify the specific model of your Anden dehumidifier before ordering to ensure you select the correct controller.

Can the A76 be used to control humidity automatically without manual intervention?

Yes. The A76's dry contact output activates the dehumidifier automatically when relative humidity rises above the setpoint (plus the 3% differential) and deactivates it when humidity drops back below the setpoint. Once installed and set, it operates continuously without requiring manual activation — making it suitable for unattended operation during lights-off periods and overnight cycles.

What does the 3% differential setting mean for day-to-day humidity control?

The 3% differential means the dehumidifier turns on when humidity rises 3% above the target setpoint and turns off when humidity falls back to the setpoint. For example, with a setpoint of 55% RH, the dehumidifier activates at 58% and deactivates at 55%. This prevents the unit from cycling rapidly on and off at the exact setpoint, which would cause excessive compressor starts and reduce equipment life over time.
