C4XC Thermostat
Line/Ambient Sensing Fixed Temperature NEMA 4X Set-Point Application/Specication Guide
DESCRIPTION
The C4XC thermostat is intended for temperature
control of a variety of electric heating cables utilized
for freeze protection pipe tracing or roof/gutter
deicing. The thermostat is suitable for indoor/outdoor
locations having hostile, non-hazardous environments. The C4XC can be used in an ambient-sensing
mode (with capillary coiled, as received) or a line
sensing mode (with capillary attached to pipe).
