文档介绍：FPS-B3 Low Temperature Cutout Control
Application
FPS-B3 low temperature cutout controls are available with SPDT contact action. Typical applications include the sensing of low temperature conditions to avoid overcooling or icing of hydronic coils, cooling coils and liquid handling pipes. The controls pact and sturdy, and have an adjustable temperature set point range with
Operation
When the temperature drops to the dial settings, the switch circuit opens, and does not close until the temperature rises to ℃ higher than the dial settings
Product installation
Mount the temperature control on a wall where it will be exposed to the average temperature of the controlled space. Do not mount where it will be affected by unusual heat or cold. Do not mount on an outside wall or where temperature at the capillary exceeds 80℃. The FPS-B3 may be mounted to the wiring conduit or to a flat surface which screws through the holes provided in back of the case.
Special Note
In the scraggly metope installation, only the top of the two mounting hole fixed. Once the scraggly metope installed and used four mounting hole fixed, may lead to shell deformation which affect the calibration value and action.
Work mode
When the temperature dropped to dial the setting temperature point, internal switch o
