The A/FLS Series Low Temperature Cutout Thermostat, otherwise known as a “Freeze Stats” are designed with a vapor charged capillary sensing element for use in equipment that requires low-temperature cutout protection. The purpose of the A/FLS Series freeze stats are to protect heating and cooling coils from freezing or to be used in any other equipment where temperature stratification may occur. All A/FLS series devices are 4 Wire, two circuit devices that can be used to shut down your system upon the air temperature reaching the low temperature limit as well as to simultaneously switch on a local indicator or remote alarm when used with your building management system or controller. The A/FLS Freeze Stats or low limit switches are available in four standard lengths with either Automatic or Manual Resets based upon the system design requirements. A NEMA 1 rated metal enclosure comes standard with a ½” conduit knockout included for all line voltage connections. An optional mounting bracket and plenum rated nylon capillary mounting clips are available and must be ordered separately as listed on the back of this data sheet.
Applications: Protect Heating and Cooling Coils, Low Temperature Limit Switch in applications where temperature stratification may occur
