1. NORMAL OPERATION
NORMAL START
Click the “Rotary switch” or “ON” button on the Wireless Remote Controller in the shutdown state to turn
the heater on. The screen will show the ambient temperature, battery voltage and the local altitude.
The unit will start pre-heating and once it reaches the required temperature, the fuel pump will start
pumping fuel. After the successful ignition, the heater will start running in about 5 minutes. The settings of
the working modes will not be initiated until completing the startup process which can take a couple of
minutes.
Note: If the pump stops ticking and the display shows OFF, error code E1, it means that the fuel did not reach the heater. You
may fulfill the fuel lines using the fuel filling mode OR repeat this Start-up process again. If the unit continues providing the same
error code, please review the placement of the fuel lines, fuel filter and fuel pump.
WORKING MODE SELECTION
●Fixed Power Mode:
To switch into the Fixed Power Mode, click the “Rotary
switch”. Turn the “Rotary switch” on the wired
controller clockwise to increase or anticlockwise to
decrease the heating power. The display will show
values between P1-P5, with P5 as the highest heating
power. The same adjustment can be achieved by short
pressing the “+” or “-” button on the Wireless Remote
Controller. After a few seconds the buzzer will beep
once as settings confirmation.
●Thermostatic Mode
To switch into the Thermostatic mode, click the
“Rotary switch”. Turn the “Rotary switch” on the wired
controller clockwise to increase or anticlockwise to
decrease the preset ambient temperature. The display
will show values in degrees celsius. You may adjust
the temperature from 10°C to 35°C. The same

adjustment can be achieved by short pressing the “+” or “-” button on the Wireless Remote
Controller. After a few seconds the buzzer will beep once as settings confirmation.
Note: The above modes are only available if the unit is in ON state. The thermostatic mode will automatically adjust the heating
power within the range of the minimal heating power and maximal heating power. The controller allows full shut-down of the
heating process after reaching the preset temperature to avoid overheating of the heated space. The unit waits fully off and
initiates the next heating cycle again once the room temperature drops a couple of degrees below preset temperature. The
temperature sensor is located in the wired LCD Switch. The two modes can only be switched and can’t coexist. For example, the
previous setting of the thermostatic mode would be invalid after switching into power mode.
SHUTDOWN
To shutdown, press and hold the “Rotary switch” or press “OFF” button on the wireless remote controller to
execute the shutdown command. The buzzer beeps once, the screen displays OFF and the heater enters the
shutdown process. It can take several minutes until the heat exchanger is fully cooled down and ready to shut
down. When the screen displays ----, the screen turns off and the heater shuts down.
Note: Never turn off the unit by disconnecting the power supply while the unit is running or before finishing the cooling
process as it may cause permanent damage to the internal components. Warranty does not cover damages like this.
2. ADVANCED FUNCTIONS
FUEL PUMPING MODE
After installation of the heater the fuel line needs to be filled up
with diesel. Press and hold the “Rotary switch” in the
shutdown state, the screen lights up and buzzer beeps once.
When the screen displays “Polr”, release the button for
executing the fuel pumping procedure. The fuel pump will
enter the state of rapid pumping (500 rapid pulses). When the
fuel enters the heater pumping frequency will be set to normal
and the heater will run automatically.
Note: This process should not be performed for regular start of the heater,
there is risk of flooding the combustion chamber.
REMOTE CONTROLLER PAIRING
For pairing the wireless remote controller the heater has to be
running in “Thermostatic mode”. Keep turning the “Rotary
Switch” anticlockwise until the screen will display “Stu”. Now
you can press the “OFF” button on the wireless remote
controller to pair it. After pairing is successful the screen will
display “433”. Now you can adjust the temperature back to the
designated value via wireless remote controller.

FUEL TANK VOLUME SETTINGS
This controller is able to measure the fuel flow and
approximate how much fuel is left in your fuel tank. You can
switch between 5l, 8l and 10l preset tanks. When the heater is
running press and hold “Fuel volume settings key”. Screen will
display the size of the tank. If you want to change the size of
the fuel tank you have to wait for the buzzer to beep and
repeat the procedure.
When you fulfill your tank you can reset the fuel gauge by
pressing the “Fuel volume settings key”.

Note: This fault code book is designed for an easy identification of any issue. Any repairs/replacements of the internal components of the
heater unit described below must be consulted and pre-approved first with the supplier of the product. The warranty will be voided if
there are any repairs/modifications or unauthorised changes in the hardware or firmware of the product without the approval of the supplier or
any replacement of non-original parts or components that are not supplied by the supplier.
E0
CONTROL UNIT
●Fault of the ECU
○Replace ECU.
●Incorrect ECU / Wired controller
○Replace ECU / Wired controller.
E1
FAILED IGNITION
●No fuel entering the heater unit
○This can happen when you run out of fuel in the individual fuel tank or the fuel level of
the main tank dropped just under the tip of the suction pipe. You must fill the tank and
then fulfill the fuel line using the Fuel pumping mode or repeat the start-up process again
and again until the successful ignition or until you remove all the bubbles appearing in
the fuel line.
●The wrong placement of fuel lines/fuel filter/fuel pump
○Problem especially on the intake side of the fuel line before the fuel pump, which is the
most vulnerable for creation of the airlock. Review the placement of the fuel line /filter/
fuel pump exactly as per the provided instructions.
If you are unsure if the problem is caused by the placement of the fuel lines (this can
happen on long horizontal fuel line), you may try to place the fuel pump directly under
the heater and suck the fuel straight from the jerry can to determine if the problem is
caused by the fuel line placement.
●Wrong diameter of the fuel lines
○The fuel lines supplied are a special size with very small internal diameter. Never use any
other type of fuel line.
●Blocked or compressed air intake / exhaust pipe
○Check the air intake / exhaust pipe for the blockage, dirt, snow, mud.
●Condensed / rain water staying in the air intake / exhaust pipe
○Reinstall the pipes per instructions to allow water to escape naturally down by gravity.
