2.1 Intended Use
The junction box with electronic thermostat module PBTC is intended for use as a temperature controller in electrical trace heating
systems.
The junction box with electronic thermostat module may only be installed in trace heating systems that have been designed by trained
and qualified personnel with specific expertise and experience in explosion protection and trace heating systems.
It can be operated only with
Resistance Temperature Device Pt100
Appropriately designed over-current protection device
The self-limiting BARTEC heating cables type PSB, MSB, HSB+ or HTSB
End cap mounted on the heating pipe end
Completely filled out acceptance test report
The junction box with electronic thermostat module may only be operated with one heating cable; the maximum permissible heating
cable length must be observed.
The approval and marking of the respective heating system, the data sheet of the heating cable type and the design guide must be
observed.
For use with electrical systems, the relevant installation and operating conditions (e.g. according to ATEX Directive 2014/34/EU, EN
60079-0, EN 60079-14, EN 60079 17, EN 60079 30 2 and any other relevant national standards) must be observed. Information on
the type plate, the EU type examination certificate must be observed. Technical data on the thermostat module and in the operating
instructions must be observed.

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).
