Resideo by HoneyWell L4008A1130 Remote Bulb Aquastat Controller F Boiler Safety Controls & Aquastats - 130-270

The Resideo by HoneyWell L4008A1130 is a remote bulb aquastat controller designed for precise temperature control in hydronic heating systems. This reliable control device monitors water temperature using a remote sensing bulb connected by a 10-foot capillary tube, allowing flexible installation in boilers, water heaters, and storage tanks.

Key Features:

• Temperature range: 130°F to 270°F for accurate control of hot water systems
• Adjustable differential: 5°F to 30°F allows customization of temperature swing
• 10-foot capillary tube provides installation flexibility for remote sensing
• Remote bulb design enables sensing in locations separate from the control unit
• SPDT switching for versatile wiring configurations
• Durable construction for long-lasting performance in demanding applications

This aquastat controller is ideal for maintaining consistent water temperatures in residential and commercial heating applications. The adjustable differential setting helps optimize system efficiency by controlling how much the temperature can vary before the heating system activates or deactivates. The remote bulb configuration is particularly useful when the control needs to be mounted away from the sensing point or when the sensing location is not suitable for mounting the entire control.
