ETS-05
Surface sensing electronic thermostat
Product Overview
The 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-L2-E is
for temperatures up to 199°C, while the ETS-05-H2-E can be
used for temperatures up to 499°C. The maximum nominal
load is 32 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.

Terminals 1 to 3 allow for the connection of a three wire PT100 sensor.
Terminals 3 to 4 allow the user to select the default heating status on sensor error.
Without a link fitted the heating will turn OFF if a sensor error is detected (default)
With a link fitted the heating will turn ON if a sensor error is detected
