WARNING:
This component 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.

DESCRIPTION
The nVent RAYCHEM ETS-05 electronic surface sensing thermostat
provides accurate temperature control for heating cables. The ETS-05
is available in two versions. The ETS-05-L is for temperatures up to
199°C (390°F), while the ETS-05-H can be used for sensing and control
of temperatures up to 499°C (930°F). The maximum nominal load is
24 A for both thermostats. Temperature setting is accurate via digital
rotary switches inside the enclosure.
The ETS-05 has a LED indicator which indicates the status of the
thermostat (powered on/off), the status of the heat-tracing cable
(powered on/off) and the status of the sensor. In case of sensor
failure the thermostat can switch to an on or off state, depending
upon the users requirement.
The ETS-05 is available in the following versions:
ETS-05
ETS-05-L1-A
ETS-05-L2-A
ETS-05-H1-A
ETS-05-H2-A

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 conductive and can short. They must
be 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.
