ACI A/FLS-10-M : Freeze Stat (FLS), 10' Capillary, Manual Reset, 4 Wires, 2 Circuits (Two Simultaneously Switching Contacts) DPDT

The A/FLS Series low temperature cutout controls have electrical contacts that operate through a temperature sensing element. On the 4-wire, two-circuit models, when a temperature decrease is detected, the main load contacts (LINE-M2) open and the auxiliary or alarm contacts (LINE-M1) close.

Use the control as a low temperature cutout device on heating and cooling coils or other applications where there is a possibility of air stratification. It responds only to the lowest temperature along any 14 in. to 16 in. (35 cm to 40 cm) length of the 6 ft, 10 ft, 20 ft or 50 ft (1.8 m, 3 m, 6 m, or 15 m) long sensing element. The sensing element is usually located on the downstream side of the coil. When the temperature along any point of the sensing element reaches the set point, the control stops the fan. Check to ensure the outdoor damper is installed in such a way that it closes when the fan stops.

A/FLS Series Auto Reset controls automatically reset their contacts to the closed position when the sensed temperature rises above the minimum temperature differential. The controls with manual reset lock out when the sensed temperature decreases below the set point. Push and release the reset button to re-close the contacts.

All A/FLS Series controls are designed for use only as operating controls. Where an operating control failure would result in personal injury and/or loss of property, it is the responsibility of the installer to add safety and limit control devices that protect against control failure, or alarm and supervisory systems that warn of control failure.
