TrueSteam HM512VPIAQ 12 Gallon Humidifier by Honeywell

Honeywell HM512VPIAQ TrueSTEAM 12 Gal Humidifier VisionPRO IAQ Comfort System

TrueSTEAM takes the best features from current steam humidifiers with their efficiency, performance and decreased water consumption, and combines it with the ease of installation, reliability and value of flow-through humidifiers. TrueSTEAM is different from others because it operates independent of equipment operation. And, with its near 1:1 humidification delivery rate, TrueSTEAM delivers the right amount of humidification.

• Provides humidity independent of equipment operation, allowing homeowners to reach their desired humidity setpoints regardless of air temperature.
• Can be remotely mounted up to 20 feet from the system with purchase of remote mount kit- available in 10' or 20'
• Uses up to 70 percent less water to produce even more moisture than traditional whole-house humidifiers.
• Requires only a 1-3/4" cut into ductwork and mounts on a separate, lightweight bracket (included) for accurate leveling.
• Push terminals for easy wiring are routed through an interior harness so no wires are exposed.
• LED lights indicate when system is running or needs service. Lights also provide feedback during installation.
• Multiple sensors sit in a separate compartment to accurately monitor water levels.
