Resideo HE100A1000 Humidifier

The Resideo HE100A1000 is a whole-house bypass humidifier engineered for precision moisture control in residential applications up to 2,000 square feet. As the direct replacement for the Honeywell 500 series, this unit integrates seamlessly into existing ductwork with a familiar footprint, significantly reducing retrofit labor. The TrueEase bypass humidifier employs an efficient flow-through design, delivering a 12 gallons per day capacity (46 liters) to combat dry indoor air and protect building materials. It features a patented one-piece frame with mounting screws located around the perimeter, allowing for a single-step installation without the need for a separate mounting bracket. For enhanced control, the package includes a HumidiPRO digital humidity control, which automates seasonal adjustments to prevent window condensation while maintaining optimal comfort levels. Technicians will appreciate the integrated wiring with push terminals and the interchangeable bypass, which can be easily flipped and snapped into place to accommodate left or right-side installation configurations without unit disassembly.

• Efficient Throughput: Provides up to 12 GPD (46 LPD) while consuming less water than traditional fan-powered units by only operating the solenoid when the HVAC blower is active.
• Contractor-Friendly Installation: Features quick-connect plumbing and a snap-into-place bypass duct, allowing for faster setup in tight mechanical rooms or near obstructions.
• Low Maintenance Design: The evaporative humidifier pad is accessible via a slide-out tray from the front or either side, eliminating the need to disconnect plumbing during annual service.
• Digital Accuracy: Includes the HumidiPRO digital humidistat with an outdoor temperature sensor to automatically adjust the setpoint based on external conditions.
• Versatile Compatibility: Designed for an evaporative flow-through configuration that works with most forced-air furnaces and air handlers using a 24VAC control circuit.

Is the HE100A1000 compatible with my older model?
Yes, this unit is the engineered HE100A1000 replacement for 500 series manual and bypass models, utilizing a similar footprint to minimize ductwork modifications.

Does this unit come with a humidistat?
This model is bundled with a HumidiPRO digital humidity control, providing more precise environmental management compared to older manual dial controls.

How often do the water panels need to be changed?
For peak performance and to prevent scale buildup, it is recommended to replace the humidifier pad at the start of each heating season, or more frequently in regions with high mineral content in the water supply.
