Resideo HE300A1005 Humidifier

The Resideo HE300A1005 is a professional-grade fan-powered humidifier engineered for high-capacity moisture delivery in residential and light commercial applications. Part of the TrueEase humidifier line, this whole-house evaporative humidifier delivers up to 18 gallons per day (GPD), making it the primary Resideo humidifier replacement for legacy units like the 32000429-001, P110-LFP1518, and 700M. It features a built-in fan to pull air directly through the humidifier pad, eliminating the need for a bypass duct and allowing for versatile installation in tight mechanical rooms or systems with limited static pressure.

For contractors, the HE300A1005 offers simplified integration with the included HumidiPRO digital humidity control. This advanced controller supports humidity on demand, capable of forcing the system fan to run even without a call for heat, provided the unit is plumbed to a hot water line. The system utilizes a powered damper to reduce water waste by up to 50% by only wetting the pad when active. Tech-friendly features like push-terminal wiring, a quick-connect plumbing gasket, and a slide-out pad design ensure rapid commissioning and maintenance.

Common Questions

Can I install the HE300A1005 if I don't have a bypass duct?
Yes. As a fan-powered unit, it does not require a 6-inch bypass duct. It mounts directly to the supply or return ductwork and uses its internal fan to circulate air through the evaporator pad.

Does this unit require a 24V transformer?
The HE300A1005 typically uses a standard 120V line cord for the fan motor and 24VAC for the control circuit. Always verify your local wiring requirements and refer to the included Resideo installation guide for specific furnace control board integration.

Which replacement pad does this unit use?
This model utilizes the standard HC26A replacement pad. The slide-out tray design allows for tool-free pad changes during seasonal maintenance.
