2. INSTALLATION
○ This controller should be
installed in a suitable location which
is convenient for operating the heater
and also connecting to the wiring loom.
○ Drill Ø12 mm hole for connection cable and
Ø6.5 mm hole for fixing screw, holes are 17 mm
apart.
○ Stick the foam sticker to the mounting
surface, push the cable through a Ø12 mm
hole. Remove the other side of the sticker
and stick the controller to it. Expansion
plugs of the controller are now in the Ø6.5
mm hole. Insert the fixing screw and place
the protective cover over it.

3. OPERATION
IMMEDIATE HEATING
○This mode is used for manual ON and OFF switching of heating with
preset power or at designated temperature.
○Select using and and confirm with .
○You can adjust heating power between 1 to 7 with arrows.
○To switch into thermostatic mode press and hold for three seconds.
Heater will start automatically after a few seconds.
○To terminate the heating cycle press . The heating unit will initiate
the cooling down process that can run a couple of minutes until the
heat exchanger is fully cooled down.
●Fixed Power Mode:
The display will show values between P1-P7, with P7 as the
highest heating power. The heater will be running on the same
until switched off or changed.
●Thermostatic Mode
The display will show values in degrees
celsius. You may adjust the temperature
from 5°C to 35°C. It automatically adjusts
the heating power within the range of the
minimum and maximum heating power and
also allows full shut down of the heating
process after reaching a few degrees
above the preset temperature. This is to
avoid overheating of the heated space. The unit then waits fully off and initiates the next
heating cycle again once the room temperature drops a few degrees below preset
temperature. The controller allows cycling to maintain a relatively stable room
temperature.
Note: The ambient temperature sensor is located inside the heating unit. It measures the temperature
of air entering the unit. You may experience incorrect functionality of thermostatic mode in case the
air for the unit is sucked from a different area than the one you are heating.

Note: Priming the fuel line can only be done while the fuel line is physically disconnected from the
heating unit as otherwise the burner could be filled with fuel and the next startup will be
unsuccessful with a lot of smoke. If the fuel line is connected to the heater unit, never use this
mode. Not following this rule can cause excessive overfilling of the burner that may require
service of the unit that can not be covered by warranty.
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 such damages.

IGNITION FAILURE
●Run out of fuel
○This can happen anytime after you run out of fuel in the individual fuel tank or
the fuel level of the main tank has dropped under the tip of the suction pipe.
You must fill the tank and then fill the fuel lines using the Pump Oil Start or
Remote Pump Oil mode or repeat the start-up process again until successful
ignition or until you remove all the bubbles sitting on the fuel line.
●Closed / blocked breathing vent of the tank
○Implosion of the tank prevents pumping the fuel. Open the breathing vent of
the tank.
●The wrong placement of fuel lines/fuel filter/fuel pump
○A problem especially on the intake side of the fuel line before the fuel pump,
which is most vulnerable for creation of an 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 due to the placement of the fuel lines (this
can occur if you run longer distance in horizontal level), you may try placing
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 as per instructions to allow water to escape naturally.
●Blocked fuel line or fuel filter
○Replace the fuel line or fuel filter.
●Bad quality of fuel
○Replace the diesel.
●Carbon deposition inside the burner
○Replace the burner.
●Carbon deposition in heat exchanger / exhaust pipe / exhaust silencer
○Pressure clean with water the heat exchanger/ exhaust pipe / exhaust silencer.
