The Raychem AMC-F5 thermostat is designed to control electric heat tracing systems used for pipe freeze protection in non-hazardous locations. The thermostat has a fixed set point of 40 deg F (4.4 deg C) and can be used in ambient sensing mode (with sensor in air) or line sensing mode (with sensor placed on pipe or tank wall). It can be used to control a single heat tracing circuit or as a pilot control of a contactor switching multiple heat tracing circuits. It can also be used to control a contactor coil.
