In the off state (LCD display is off and you wait at least 10
seconds since the heating unit was switched off), long
press and hold the middle of the "Rotatable Dial" on the
Main Controller to scroll through the menu. Release the
button to enter the mode you selected from the menu.
Continuous holding of the middle of the "Rotatable Dial"
will cycle through the menu repeatedly until you release the
button.

Po - PUMP OIL START
This mode is used after the first installation of the unit or if the unit shuts down because the fuel
tank ran out of the diesel and the display shows error code E1. This mode works very similar to
the Normal Start with a difference in higher frequency of pumping allowing priming of the fuel
lines much faster. Once the fuel reaches the heating unit and the heater initiates the ignition, the
heater continues in Normal heating mode. To Shut down this mode, short press the middle of
the "Rotatable Dial" on the Main Controller or OFF button on the Wireless Controller, display
shows “--” and voice over will say “Power Off”.
Note: If the pump stops ticking and the display shows error code E1, this indicates that the fuel did not reach the
heater. You may repeat this process again. If the unit continues providing the same error code, please review the
placement of the fuel lines, fuel filter and fuel pump.
Fn - VENTILATION MODE
This mode is used for regulated flow of cold air through the heating unit without the heating
process. Turn the "Rotatable Dial" on the Main Controller clockwise to increase or anticlockwise
to decrease the speed of the fan. The display will show values between F1-F5, with F5 as the
highest speed of the fan. The same adjustment can be achieved by pressing the UP or DOWN
button on the Wireless Controller. To shut down this mode, short press the "Rotatable Dial" on
the Main Controller or OFF button on the Wireless Controller.
rL - REMOTE RE-MATCHED
Remote matching (pairing) mode is used after the first installation, after replacing the battery in
the Wireless Controller or after replacing the Wireless Controller. This step is necessary for the
right functionality of the Wireless Controller. After entering into this mode, the display will show
r9, r8, r7..until it switches off. You must short press the UP button on the Wireless Controller as
soon as possible otherwise the 10s countdown will shut down this mode. If the matching was
successful, the display will show “--” immediately after pressing the UP button and the
voice-over will say “Power Off”. If the matching was unsuccessful, the countdown continues
until r1 value, the display shows “--” and voice over will say “Power Off”.
Note: If the matching is continuously unsuccessful, please replace the battery in the Wireless Controller (You must
use the model A27 12V or CR2032 3V depending on the model of your wireless remote).
rP - REMOTE PUMP OIL
This mode is used after the first installation of the unit and may be used only by the installation
technician allowing to remotely turn on/off the high frequency pulses powering the fuel metering
pump. This provides an extremely fast pumping process to prime the fuel lines without initiating
the heating process (no waiting for ignition) and is a great tool to diagnose any issues in the fuel
lines while the technician is directly observing the fuel line etc. and does not have direct access
to the Main Controller. Display will show “20”. To start the pumping, short press ON or UP
button on the Wireless Controller. To stop the pumping, short press the OFF or DOWN button
on the Wireless Controller. This can be repeated multiple times. To shut down this mode, short
press the ""Rotatable Dial"" on the Main Controller.

Note: This process 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 and rather
fill the lines by Pump Oil Start that automatically activates the glow plug to prevent any
overfilling. 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.

3. STANDARD OPERATION
NORMAL START
In the off state (LCD display is off), short press the middle of the "Rotatable Dial" on the Main
Controller or ON button on the Wireless Controller.
The unit will start pre-heating the glow plug 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 error code E1, it means that the fuel did not reach
the heater. You may fill 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.
Fixed Power Mode
Thermostatic Mode

WORKING MODE SELECTION
●Fixed Power Mode:
To switch into the Fixed Power Mode, long press the "Rotatable Dial" on the Main
Controller for more than three seconds, the voice-over will say “warm air mode”. Turn
the "Rotatable Dial" on the Main 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
UP or DOWN button on the Wireless Controller.
●Thermostatic Mode
To switch into the Thermostatic mode, long press the "Rotatable Dial" on the Main
Controller for more than three seconds, the voice-over will say “air-condition mode”.
Turn the "Rotatable Dial" on the Main 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 UP or DOWN button on the Wireless Controller.
AVAILABLE MODELS
VMC - FS is equipped with a fuel-saving thermostat that
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.
VMC - BS is equipped with a battery-saving thermostat that also fluently regulates the heating power
based on the room temperature, but continues in the lowest heating power after reaching the preset
temperature to keep electrical consumption and noise level extremely low. To avoid overheating of
space, it's recommended to balance the heat loss being at least equivalent to lowest heating power
(this can be achieved by partially opening the roof vent etc.).
Note: Your heater supports only one of the above thermostatic modes depending on the version you have
selected during the purchase (VMC - FS / BS ). For best results in delivering designated heating you should install
the Main Controller far from heat sources (fridge, stove, hot air vent) and also away from colder spots (windows,
doors, ventilation) as the temperature sensor is located in the Main Controller.
SHUTDOWN
To shutdown, short press the middle of the "Rotatable Dial" to complete the shutdown
command. The voice-over will say “Power Off.” The display will turn off and the heating unit will
initiate the cooling down process that can run a couple of minutes until the heat exchanger is
fully cooled down.
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.

4. FAULT CODES / TROUBLESHOOTING
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

FAILED IGNITION
●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
