Ranco J10-809W Dehumidistat 24V Wall Mount Humidity Control 20-80% RH White

The Ranco J10-809W is a wall-mount dehumidistat designed to regulate the relative humidity of confined spaces by cycling dehumidifying equipment. This 24V low-voltage humidity control features an adjustable range of 20% to 80% relative humidity, making it ideal for central HVAC systems, ventilation fans, portable dehumidifiers, and materials processing applications.

Key Features:

• Improved woven nylon sensing element provides 12 times faster response than film nylon elements
• High-impact plastic construction with brushed finish dial plate eliminates need for grounding
• Can be wired in series or parallel with 24V non-electric thermostats
• SPST switch with 50,000 automatic cycle rating at 140°F
• 5% or 15% relative humidity differential settings
• Greater stability of setpoints over dramatic changes in humidity
• White finish suitable for residential and commercial installations

Specifications: 24/60V AC electrical rating, operating temperature range 32°F to 140°F, wall or duct mount capable. The sensing element changes length in response to relative humidity to actuate the switch at appropriate setpoints. Certified to UL 873, CSA C22.2, and IEC 60730 standards.

This unit replaces the older J10-809 model and is compatible with humidifying and dehumidifying equipment in central systems.
