Aprilaire 5558 Humidistat
The Aprilaire 5558 is a high-performance Automatic Digital Modulating Control package engineered specifically for use with the Model 866 modulating steam humidifier. This modulating steam humidistat provides superior precision by utilizing a microcomputer-based design and a proportional algorithm. Unlike standard on/off controls, the 5558 delivers a 0-10VDC or 2-10VDC modulating output signal, allowing the humidifier to adjust its output based on the exact gap between the sensed relative humidity and your desired set-point. This wall-mounted unit features a large, backlit LCD digital display for easy monitoring and a multi-level lockable access menu to prevent unauthorized adjustments. By including an outdoor temperature sensor, the system can automatically perform humidity set-point reset, which lowers indoor humidity levels as the outside temperature drops to prevent harmful window condensation. Whether managing a residential space or a specialized environment, the Aprilaire 5558 ensures consistent, accurate moisture control for optimal air quality.
Key Benefits:- Precise Humidity Control: Uses a proportional algorithm and modulating output signal for exact moisture management.
- Condensation Prevention: Includes an outdoor temperature sensor for automatic set-point adjustment in cold weather.
- Enhanced Visibility: Features a large, backlit digital display showing both humidification and dehumidification status.
- System Security: Equipped with a lockable set point and access menu to maintain consistent settings.
- Versatile Compatibility: Specifically designed as the primary control for the Aprilaire Model 866 ductless steam humidifier.
Does this humidistat work with any Aprilaire model?
The Model 5558 is specifically optimized for the Aprilaire 866 modulating steam fan pack. For other models like the 800 or 801, different control packages may be required.
Why is the outdoor sensor necessary for the Aprilaire 5558?
The sensor allows the Automatic Digital Modulating Control to track outdoor temperatures, ensuring that indoor relative humidity does not reach levels that cause frost or water damage on windows.
Can I lock the settings on this device?
Yes, the 5558 features a multi-level lockable access menu, making it ideal for environments where you want to prevent accidental or unauthorized changes to the humidity levels.
