Anden Digital Humidistat for Steam Humidifier

Precision Digital Humidistat for Anden Steam Humidifiers

The Anden Model 5558 Digital Humidistat is designed specifically for Anden steam humidifiers. It monitors relative humidity via an integrated sensor and controls the humidifier's output to maintain the set target RH level. The 5558 provides both humidification and dehumidification control outputs, allowing it to manage two-directional humidity control from a single device.

The 5558 features a multi-level lockable access menu and a lockable RH set point. The lockable controls prevent accidental adjustments to critical humidity settings — important in facilities where multiple people have access to the growing environment. Temperature display is selectable between Celsius and Fahrenheit to suit different operator preferences.

Key Features & Benefits

• Integrated RH Sensor — Built-in sensor monitors relative humidity at the humidistat's mounting location.
• Humidification and Dehumidification Outputs — Controls both directions of humidity adjustment from a single unit.
• Lockable Set Point — Set point can be locked to prevent accidental changes by unauthorized personnel.
• Multi-Level Access Menu — Multi-level lockable menu provides tiered access control for different user roles.
• Celsius/Fahrenheit Selectable — Temperature display switches between °C and °F to match operator preference.
• Designed for Anden Steam Humidifiers — Built specifically to integrate with the Anden steam humidifier product line.

Who Should Use This Humidistat

The Anden 5558 is used in Anden steam humidifier installations to provide precision humidity monitoring and control. It is included with the AS35FP model (DH4AS35FP) and is also available separately for installations where replacement or standalone deployment is required.

One-Directional vs. Two-Directional Humidity Control

A basic humidistat controls only humidification — activating the humidifier when RH drops below the set point. The Anden 5558 provides two-directional control: it can activate a humidifier when RH is too low, and signal a dehumidifier or ventilation system when RH is too high. This makes it useful as a central humidity management interface in grow environments where both over-humidification and under-humidification must be addressed.
