7 Functional Description
The thermostat module ETM-25Ex-C switches the connected heating load or heating cable on or off by means of a built-in relay. It
switches on when the temperature measured at the Resistance Temperature Device Pt100 is lower than the temperature setpoint. It
switches off if the measured temperature is higher than the set temperature plus hysteresis. The thermostat module switches the
heating load or the heating cable on when the temperature at the Resistance Temperature Device Pt100 falls below the adjusted
temperature set point.
Toggle switch °C / °F is used to switch the temperature unit, 3 rotary coding switches are used to set the temperature setpoint.
The connected Resistance Temperature Device Pt100 measures the actual temperature and ensures the temperature control func-
tion.
In case of a malfunction of the thermostat module or the Resistance Temperature Device Pt100, the thermostat module switches off
the connected heating load or the heating cable.
The electronic thermostat module has a limited service life, which depends on the switching cycles performed. A color and blinking
code of the LED status display indicates the achieved 80% service life. It is an indication that the thermostat module needs to be
replaced. When the 100% service life is reached, the thermostat module switches off the connected heating load or heating cable.
The LED status display shows a further color and blinking code.
8 Transport
Sensitive components such as sensors are installed inside and outside the junction box with thermostat module. These must be
protected from damage such as impact, moisture and dirt. Careful transport of the junction box with thermostat module must be
ensured.
NOTICE
Plant damage possible due to improper transport
Transport connection housing with thermostat module properly
Transport connection housing with thermostat module only in original packaging
Protect the connection housing with thermostat module from damage (e.g. due to impacts, moisture, contamination).
WARNING
Risk of fire and electric shock!
Danger of injury from electric current
Transport connection housing with thermostat module properly
Protect the connection housing with thermostat module from damage (e.g. due to impacts, moisture, contamination).

Safety Instructions
WARNING
Risk of fire or electrical shock due to electric trace
heating system.
De-energize all power circuits before installation or
servicing. Always use ground fault equipment protec-
tion with the trace heating system.
Keep the trace heater ends dry before and during in-
stallation. Observe the design guide of the trace heat-
ing system.
Double-check that all power circuits are de-energized be-
fore you begin your work.
Make sure that you do not exceed the maximum heating
circuit length for the trace heater type you use.
Observe the bending radius of each type of trace heater.
Do not bend on the narrow axis.
To avoid short circuits, do not connect the trace heater bus
wires together. Installing the End seal properely
Keep all components and the trace heaters dry before and
during installation.
Installing the Heating Cable
CAUTION
Risk of injury and/or material damage. Never step on or
drive over the trace heater. Do not use it as a loop for
stepping on.
Install the heating cable in a straight line along the pipe if
possible
If possible, install the heating cable in the lower half of the
pipe, but not at the lowest point
If necessary, return the heating cable loop to the heating
cable at the greatest possible distance
Install the Resistance Temperature Device directly on the
pipe
Install the Resistance Temperature Device in the lower
area of the pipe cross section
Install the Resistance Temperature Device at the greatest
possible distance from the heating cable
Observe additionally required heating cable lengths (as-
sembly of connections, T-branches and end terminations,
each approx. 0.5 m)
Avoid damage to the heating cable and the Resistance
Temperature Device: no bending, pinching or pulling over
sharp edges

Pre-assembling the Mounting Stand
Feed the heating cable through the lower part of the mount-
ing stand.
Do not fix the mounting stand on the pipe yet.
Slide a trace heater grommet onto the trace heater and into
the seal seat.
Slide the other trace heater grommet into the free seal
seat.
Make sure that the trace heater stands out approximately
25 cm. This makes cable preparation easier.
Ensure that all heating cable feed-throughs of the lower
part of the mounting stand are filled with heating cable
seals
