FS-4A | ACI: FreezeStat, (2) SPDT, 10′, Auto Reset

FS Series controllers from ACI are low limit controllers, also known as “Freeze Stats”. These devices were designed for use on HVAC equipment that requires low-temperature cut-out protection to prevent cooling coils from freezing.

FS Series controllers respond to the lowest temperature sensed along any 1 foot section of the sensing element. They should be mounted between the heating and cooling coils on the supply side of the fan unit. The FS Series includes manual and automatic reset versions as well as models with one or two sets of SPDT contacts.

Features include:

• Adjustable setpoints
• Manual or Auto reset versions
• Available in lengths up to 20 feet

For convenience in installing a complete building automation system, KMC Controls sells to our customers a large variety of ACI (Automation Components, Inc.) devices.
