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.

display will show “--” and voice over says “Power oﬀ”.

oN - NORMAL START

By entering this mode, the heater unit will start the normal start operation as described below.

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

voided if there are any repairs/modiﬁcations or unauthorized 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.

CONTROL BOX

●Fault of the ECU (internal Electronic Control Unit)

○Replace ECU.

●Wrong connection of the data communication wire / fault of wiring harness

○Check with a multimeter the connection of the blue communication wire coming to the controller.

○Inspect wiring for damage or short circuiting with the chassis of the vehicle. Check continuity

from the ECU board to the connector for the Main Controller. Check especially that terminals are

locked In plastic connector housing. Fix or replace a wiring harness.

CONTROL UNIT

●Fault of the ECU* please see above

●Incorrect ECU / Main Controller

○Replace ECU / Main Controller.

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

○Pressure clean with water the heat exchanger/ exhaust pipe / exhaust silencer.

●Dirt on the atomising net of the glow plug

○Replace the atomising glow plug net

●Dirt on the glow plug

○Replace the glow plug

●Faulty blower motor / heat exchanger gasket OR burner / heat exchanger gasket

○Replace the gasket

UNDERVOLTAGE

●Undervoltage

○System minimum voltage is 10.5 volts. Verify battery voltage. Connect the multimeter to the

positive and negative terminals of the wiring harness and set to volts DC. If the wiring harness

has been extended for a longer distance, check the voltage at the main ECU connector.

○Record the voltage. If the voltage is less than 12.6 (ﬂooded cell) 12.8 (AGM), connect the battery

charger and log oﬀ the job until the batteries are fully charged. Otherwise, turn on the unit while

watching the multimeter.

●Overvoltage

○System maximum allowed voltage is 15 volts for the 12V version and 30 volts for the 24V

version. The possible causes of this code are: 1) Battery charger in boost mode 2) Alternator

overcharging 3) Solar panel controller overcharging

●Wrong connection in connectors

○Check the connector of the main ECU board for any dirt or corrosion on the positive and

negative terminal at the wiring harness.

●Fault of wiring harness

○Inspect wiring for damage or short circuiting with the chassis of the vehicle. Check continuity

from the ECU board to the connector of the Main Controller. In case of wrong connection,

replace a wiring harness.

●Fault of the ECU * please see above

INTAKE

OVER-TEMPERA

TURE

●Excess temperature is measured at the cold air intake sensor

○The indoor temperature is too high

○Installation space is too narrow or the suction vent of the installation enclosure is blocked which

causes accumulation of residual heat around the heating unit.
