Anden Digital Humidistat for Steam Humidifier

Digital Humidistat with Lockable Setpoint for Anden Steam Humidifiers

A shared or high-traffic grow space is an easy place for a humidity setpoint to get bumped by accident, and a facility running a precision steam humidifier doesn't want that setpoint drifting without anyone noticing. The Anden 5558 Digital Humidistat pairs a precise RH sensor with a lockable interface built to prevent exactly that kind of accidental change.

The 5558 monitors relative humidity through its own integrated sensor and controls both humidification and dehumidification outputs from a single interface, with the display selectable between Celsius and Fahrenheit. Its multi-level lockable access menu and lockable set point keep day-to-day staff from adjusting the target humidity unintentionally.

Key Features & Benefits

• Integrated RH Sensor — Monitors relative humidity directly rather than relying on a separate sensor accessory.
• Humidification and Dehumidification Outputs — Controls both sides of humidity management from one interface.
• Selectable Celsius or Fahrenheit — Displays readings in whichever unit your facility standardizes on.
• Lockable Set Point — Prevents the target humidity from being changed accidentally.
• Multi-Level Lockable Access Menu — Restricts deeper configuration settings from casual or unauthorized adjustment.

Who Should Use This Humidistat

The 5558 is built specifically for Anden steam humidifiers, so it fits facilities running an AS35FP, AS150, or similar Anden steam unit that needs precise, tamper-resistant humidity control. Shared or high-traffic grow spaces benefit most from the lockable set point, since it keeps the target humidity from drifting through accidental adjustment.

Why a Lockable Set Point Matters for Steam Humidification

Steam humidification systems are typically sized and tuned for a specific target humidity range, and an accidental setpoint change can push a room outside that range without anyone realizing it until symptoms show up in the crop. The 5558's multi-level lockable access menu separates routine monitoring from configuration changes, so day-to-day staff can check readings without being able to alter the underlying setpoint.

Frequently Asked Questions

Which Anden humidifiers is the 5558 compatible with?

The 5558 is designed for Anden's steam humidifier line, including models like the AS35FP that ship with it included as standard equipment. It's also sold separately as a replacement or spare control.

How does the lockable set point work?

The set point can be locked through the humidistat's multi-level access menu, preventing changes without going through the unlock process first. That keeps the target humidity from being bumped accidentally during routine facility activity.

Can I switch between Celsius and Fahrenheit?

Yes, the display is selectable between Celsius and Fahrenheit, so the unit can match whichever temperature and humidity convention your facility already uses. That flexibility matters for operations standardizing equipment readouts across multiple rooms or facilities.

Does this control both humidifying and dehumidifying?

Yes, the 5558 controls humidification and dehumidification outputs from a single interface. That lets one device manage both sides of humidity control rather than needing separate hardware for each function.

How is the 5558 different from the A76 or A77 dehumidifier controls?

The A76 and A77 are built specifically for Anden's dehumidifier line, while the 5558 is built for Anden's steam humidifiers and manages both humidification and dehumidification outputs. They're not interchangeable across product lines.
