WARNING:
This component is an electrical device that must be
installed correctly to ensure proper operation and to
prevent shock or fire. Read these important warnings
and carefully follow all of the installation instructions.

or improperly installed, and to comply with the
requirements of nVent, agency certifications,
DESCRIPTION
The nVent RAYCHEM EC-TS electronic thermostat is an
ambient, pipe, or slab sensing thermostat that is ideal for pipe
freeze protection, flow maintenance, freezer frost heave and
floor heating and snow melting applications. The EC-TS can
be used to control a single heat-tracing circuit or as a pilot to
control a contactor switching multiple heat-tracing circuits.
The temperature set point can be visually checked through the
clear lid, as can the LED indicators for alarm, power and heating
cable status. The stainless steel sensor makes it an ideal
thermostat for applications that require an embedded sensor.
The set point range for these thermostats is between 30°F
(–1°C) and 110°F (43°C). It operates at voltages between 100 to
277 Vac and switches current to 30 Amps.

and the National Electrical Code, ground-fault
equipment protection must be used. Arcing may
not be stopped by conventional circuit breakers.
• Component approvals and performance are based
on the use of nVent-specified parts only. Do not
use substitute parts or vinyl electrical tape.
• The black heating cable core and fibers are

properly insulated and kept dry.
• Damaged bus wires can overheat or short. Do
not break bus wire strands when scoring the
jacket or core.
• Keep components and heating cable ends dry
before and during installation.
• Use only fire resistant insulation materials, such
as fiberglass wrap or flame-retardant foam.
