Features of Raychem AMC-1A Ambient Sensing Thermostat

The Raychem AMC-1A ambient-sensing thermostat is designed to control heat tracing systems used for freeze protection in NON-HAZARDOUS locations. The thermostat responds to ambient temperature changes and has an adjustable set point. The AMC-1A can be used to control a single heat tracing circuit or as a pilot control of a contactor switching multiple heat tracing circuits.
