Aci A/FLS-06-A Freeze Stat (FLS), 6 feet Capillary, Automatic Reset, 4 Wires, 2 Circuits

Product Description

The ACI A/FLS-06-A freeze stat is a low limit controller designed for HVAC equipment needing low-temperature cutout protection to prevent cooling coils from freezing. It should be mounted between heating and cooling coils on the supply side of the fan unit and responds to the lowest temperature sensed along any 1 foot section of the sensing element.

• Available with 6, 10, and 20 foot length capillaries
• Adjustable set-point
• Manual reset and automatic reset versions

Product Highlights

This freeze stat protects heating and cooling coils and features a low temperature limit switch for applications where temperature stratification may occur.
