Linear Control: Provides predictable flow modulation for accurate HVAC zoning and energy efficiency

If the noise originates from a cracked or loose housing rather than the motor bearings

preventing the common communication errors associated with generic alternatives

Standardized Integration: Compatible with 120V electrical systems

the assembly includes the necessary 30-inch capillary and sensing bulb intended for mounting on the suction line to monitor evaporator outlet temperature

Aprilaire 5558 Humidistat 326070-701 Linear Control: Provides predictable flowThe 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
