OPERATING INSTRUCTIONS FOR ALDE COMPACT 3020 HIGH EFFICIENCY
1. CHECKING THE HEATING SYSTEM BEFORE USE
• Check the glycol fluid level in the expansion tank: the level should be approx. 1 cm above the min. line
when the system is cold. Ensure that the system is properly bled before it is put into operation.
Warning! The boiler must not be started if there is no glycol fluid in the system.
Warning! Do not mix dierent types of glycol; this can lead to coagulation of the glycol fluid.For more
information on the glycol fluid, see section 12.
• Check that the flue is kept free of snow and ice, as induction air enters the boiler via the flue when
operated on LPG. Also check that other objects are not obstructing or disrupting flue gases and sup-
ply air at the flu. Tip! A flue extension (part no. 3000 320) is recommended for the roof flue for camping
in winter.
Warning!The boiler must not be allowed to run on LPG in an enclosed space such as a
garage or similar. Make sure also that the flue does not exit in an enclosed space, e.g.
under an awning, as this can lead to a risk of carbon monoxide poisoning.
• Check the air circulation. Make sure there are no obstructions preventing air circulation (convection).
In order to exploit the water-borne heating to the full, it is important that air can circulate freely under
bunks, and behind backrests and wall-mounted cabinets. If the vehicle has a fitted carpet, ensure that
the carpet does not obstruct the air supply to the convectors. It is just as important that cushions and
blankets do not obstruct and prevent the flow of air behind backrests.
2. THE FIRST TIME THE HEATING SYSTEM IS STARTED
• Hot water heater: Always flush the water heater before using for the first time or if it has not been
used for a long period. Then fill the water heater with water – see the separate instructions for the
vehicle. The boiler can equally well be used without any freshwater in the heater.
NB. Hot water from the boiler is not intended as drinking water or for preparing food.
NB. Freshwater in the heater should always be drained when there is risk of frost or there is
a risk of the boiler freezing.
The warranty does not cover frost damage.A frost guard can be installed to reduce the risk
of freezing (part no. 3010 430 and 3010 431).
NB.Remember that the water in the water heater may be hot.
• Carry out a check as in section 1 (Checking the heating system before use).
• Start the boiler as described in section 3.
• Select language, this appears when the panel is started for the first time, see section 7:1 point 22.
• Check that the right accessories have a checkmark next to them in the list of installed functions, see
section 11.
• Set the clock, see section 7:1 point 4.
• Set the desired operating mode (gas and/or electric) and the desired interior temperature, see
sections 5:1, 5:3 and 5:4.
The LPG boiler and electric elements can be operated simultaneously, but this should be avoided in
newly filled systems.
NB. The boiler uses no more power than is needed, even if it is set for both 3kW electricity and gas.
Please read these instructions carefully before using the boiler for the first time.
For installation guidelines, see the separate instructions. These instructions are approved for
the Alde Compact 3020 boiler fitted in vehicles in accordance with CE 0402 no. SC0653-13 and
have the E5 mark for installation in vehicles in accordance with R122 and R10. Installation and
repairs may only be carried out by a specialist. Always comply with national regulations.
This appliance may be used by children from the age of 8, persons with reduced physical or
mental capacities or persons lacking in experience and knowledge provided they have been
instructed in safe use of the system and understand the risks involved.
Children should not be allowed to play with the appliance. Children must not be allowed to per-
form cleaning and maintenance unless supervised.

10. *Load monitor
The function prevents overload of the
fuses on 230 V. If the total current con-
sumption of the vehicle exceeds the set
value, the electrical output of the boiler
will be reduced automatically. This also
applies to Truma Comfort AC if connec-
ted to the Alde 3020. Due to voltage fluc-
tuations and tolerances, dierent regula-
tion levels can be selected (5-17 A). If the
fuse blows repeatedly, choose a lower
setting.
NB.For ACC to function with the load
monitor, ACC must be on from the panel
and not via the remote control.
11. *Booster
Control of booster in two dierent
speeds. Fan start and stop is controlled
from the boiler. If the boiler’s circulation
pump starts up, the fan on the booster
will as well. When the circulation pump
stops, the fan will continue to run for
another six minutes. It will then stop
unless the circulation pump has started
up again.
12. *Underfloor heating
The function governs the underfloor
heating pump’s operation in intervals,
which means that the underfloor hea-
ting pump is in operation for 5 min
and is then o for 5 min when heat is
required.
Mode: Make sure Delay or Cont. is
activated; in these two modes, under-
floor heating is switched on. In O
mode underfloor heating is o.NB. In
Cont. mode it can get hotter in the
vehicle than desired, as the heat con-
trol is disabled!
Delay:The underfloor heating pump
is on for a certain period after the
boiler’s circulation pump has stopped,
this Delay can be set at 15 min, 30 min

matically.
NB.The clock in the panel must be set
for the function to work.
14. Automatic temperature increase
The boiler will start at 02.00 in the
morning (if the clock is set) and run
as indicated for ”More hot water” for
30 minutes (see section 5:2). This is to
reduce the risk of legionella.
15. Oset (temperature adjustment)
If the temperature that is displayed in
the panel does not correspond to the
actual temperature, it can be adjusted
by ±5°C in the panel. Applies also to
display of external temperature.
16. High altitude mode
The function should only be used if
the boiler will be powered by LPG at a
height above 1000 m above sea level.
NB. For LPG operation at high altitude,
use propane to obtain stable com-
bustion. NB. Variations in operating
conditions at high altitudes can mean
that the boiler always achieves stage 1
output, but not always stage 2 on LPG
operation.
Functions marked with a (*) are accessories, which are not installed on all vehicles, refer to the vehicle
manufacturer’s instructions.

9. TROUBLESHOOTING
Always start by checking any error messages.
If a fault occurs in the system, the cause will be shown on the display. This is only displayed when the control
panel is in standby mode.
The boiler will not start on gas
• No LPG?
• Is the main tap fully open?
• Check that the type of LPG used is suitable for the prevailing outdoor temperature. Using butane is unsui-
table at temperatures lower than +10°C. Use propane instead.
• Check that the fuse for the boiler has not blown.
• Check that power at 12 V is being supplied to the boiler (> 11 V); the current voltage can be read o from
the
service menu.
• Check that the exhaust hose is secured properly between the boiler and flue and that it is not damaged or
blocked with dirt, condensation or water. NB. The exhaust hose consists of two hoses, an inner one and an
outer one.
• Check there is nothing obstructing/blocking the path of the exhaust gases at the flue.
• Check for correct gas pressure. This can be done by starting all hobs on the gas cooker and then starting
the boiler on gas operation. If there is a reduction in flame on the cooker, the gas pressure is incorrect.
• If the boiler has not been operated for some time, or if the LPG cylinder is new, it may take longer than
normal to light the boiler. Try to restart the boiler.
• If none of the above helps, contact a service workshop
The electric element is not working
• Check that the fuse for the boiler has not blown.
• Check that power at 12 V is being supplied to the boiler (> 11 V); the current voltage can be read o from
the
service menu.
• Check that 230 V really is being supplied to the boiler. Long and/or flimsy connection cables result in gre-
ater voltage drop and the voltage sometimes being lower under certain conditions.
• Check that the output level selected on the panel is high enough, see section 5:3.
• Check that the load monitor* (where present) has been correctly installed.
• If none of the above helps, contact a service workshop
Poor heat or none at all (circulation in the heating system)
• Check that the symbol for the circulation pump is visible in the standby menu when heating is required,
see section 4.
• Check that the circulation pump is working.
• Check that the correct circulation pump is activated in ”Installed Accessories”, see section 11.
• Check that the heating system has been bled.
*ACC not working satisfactorily
• Ensure that the temperature sensor that is used reacts eectively to the room temperature for both hea-
ting and cooling. To increase sensitivity, a more open temperature sensor can be used (part no. 3010 638).
• With an outside temperature sensor (part no. 3010 299) fitted, ACC function is improved: if the outdoor
temperature is too low, the AC should not run at all.

9:1 ERROR MESSAGES
Low battery: If the vehicle has a battery voltage of less than 10.8 V, the boiler will stop. This is reset auto-
matically once the voltage reaches 11 V. If the voltage becomes lower, various error messages may also
occur. These are not genuine faults. Ensure that the boiler has the right voltage.
Fan restarts: Incorrect fan speed. New start attempt is made. Repeated faults results in Fan failure.If Fan
failure recurs after resetting, contact a dealer. If Fan restarts is displayed, no action is necessary.
Gas failure: The boiler has not managed to ignite the LPG flame. Ensure that gas is available.
Overheat red fail: Overheat protection (red cable) tripped. This fault can arise if the boiler is run at high
power at the same time as there are air pockets in the heating system, the heating system should then be
bled properly.
If the fault remains, contact a dealer.
Overheat blue fail: Overheat protection (blue cable) tripped.
Overheat PCB: The boiler’s circuit board has overheat protection. If this gets too hot, the protection is
tripped. Allow the boiler to cool down before resetting.
* Window open: A window is open and the boiler stops running on gas. Gas operation of the boiler will
restart once the window is closed. Electrical operation continues to function.
Heater not found: There is a connection fault between the boiler and the control panel.
3rd party C. fail: Communication fault between Alde’s panel and Alde Smart Control*.
Panel failure: Fault on the panel.
No match Heater/Panel: The circuit board in the boiler is not intended for the AldeCompact3020 HE
and will not work with the 3020 HE panel.
Red connection fail: Problem with the red cable or red ports. There is no communication with the 3020
heater, AC or iNet.
Yellow connection fail: Problem with the cable between the Alde panel and the CI master panel or its ports.
iNet connection fail: Cannot find the INet box. Probably a problem with iNet. In the event
of ”INet connection fail”, this button is displayed. Pressing the button will remove the error.
Heater not found: Cannot find the 3020 heater. Most probably a problem with the heater’s circuit board.
To reset some of the errors and restart, switch o the boiler from the panel, disconnect 230 V to the
vehicle and disconnect 12 V from the boiler.

12. CARE AND MAINTENANCE
• Checking and changing glycol mixture. Regularly check the heating system’s fluid level in the expansion tank.
With the heating system cold, the level should be about 1 cm above the minimum mark. The heating system
should be filled with a fluid mixture made up from distilled water and ethylene glycol. For best results, use
high-quality ready-mixed ethylene glycol (with inhibitors) intended for use in aluminium heating systems.
The proportions when using concentrated ethylene glycol are 60% distilled water (or water that is free of
salts) and 40% ethylene glycol. If the heating system is likely to be exposed to temperatures below -25°C, the
ethylene glycol content must be increased, but should not exceed 50%. The ethylene glycol mixture should
be changed every other year, as certain properties such as corrosion protection deteriorate over time. If Alde
Premium Antifreeze is used, the interval for changing the mixture can be extended to five years under normal
operating conditions. If the fluid level is too low, the ethylene glycol content must be checked before topping
up. This is to prevent excessive concentration of ethylene glycol in the mixture. When topping up, use the
same quality of ethylene glycol mixture as is already in the system, alternatively use Alde Premium Antifreeze,
which is compatible with most ethylene glycol brands on the market.
NB. Any vessels used for handling or mixing the liquid must be spotlessly clean. This is to prevent the growth
of bacteria and corrosion in the system. The boiler must not be started if there is no glycol fluid in the system.
• Filling with glycol fluid. The system is filled through the expansion tank, either manually or using the Alde
filling pump (1900811), which both tops up and bleeds the system. For manual filling, unfasten the circulation
pump nut (R) and then lift the pump *(S) out of the tank. Slowly pour the ethylene glycol mixture into the
tank.
Bleed the system. Top up with more fluid if the level has fallen after bleeding. Bleed a newly filled heating
system regularly during the first days it is in operation.
• Checking the LPG system. The LPG system should be checked regularly by a specialist, who will ensure that
there are no leaks from connections or hoses. LPG hoses should be changed as indicated on the date stamp,
as they tend to dry out and crack, and are liable to leak as a result. For increased safety, we recommend fit-
ting an Alde leak detector, type 4071, as close as possible to the reducing regulator.
• Emptying the hot water heater. The boiler is fitted with a built-in hot water heater which can hold approxi-
mately 8.5 litres of freshwater. The hot water heater can produce around 12 litres of 40°C water per half-hour
(at a cold water temperature of 10°C). If the electric elements are used instead of gas for heating the water
heater, the capacity is slightly reduced. Always renew the air cushion in the water heater after 10 days of use.
This can be done by opening the safety/drain valve on the boiler for a few seconds.
For emptying specially-adapted boilers, as well as the vehicle’s general freshwater system, please refer to the
manufacturer’s instructions.
NB. The hot water heater should always be drained down completely when there is a risk of frost
and when the vehicle is not in use. The warranty does not cover frost damage.
NB. Remember that the water in the water heater may be hot.
Draining the water heater using the combined safety/drain valve: (see page 15)
• Switch o the freshwater pump.
• Open all water taps.
• Then open the safety/drain valve by raising the yellow lever (M) to a vertical position, or by turning the knob
(K) 180°. The heater will now drain directly below the vehicle through the safety/drain valve hose. Check that
all the water is emptied out (about 7-10 litres). Leave the valve in the open position until the next time the
heater is used.
NB. Check that the automatic non-return valve (N) is open and is allowing air to enter the heater when it is
being drained, and that the hose is not blocked.
• Bleeding the system. Depending on how the pipes have been fitted, air pockets may form when the system
is filled with glycol fluid. If the pipes only warm up a metre or so from the boiler, even though the circulation
pump is operating, this is a symptom of air trapped in the system. In a newly filled system, small air bubbles
can form in the expansion tank, resulting in a gurgling sound. Switch o the circulation pump for a few sec-
onds to allow the bubbles to disappear.
Bleed as follows: If a bleed screw is fitted to the outgoing pipe of the boiler, open this screw and leave it open
until fluid starts coming out. If the boiler is equipped with an automatic air bleed valve, bleeding the boiler
takes place automatically. Start the LPG boiler. The circulation pump should be switched o. Open the re-
maining bleed screws in the system (please refer to the instruction manual of the vehicle for their locations).
Leave the bleed screws open until glycol fluid starts coming out of them, and then close them. Start the cir-
culation pump and let it run for a while. See if the pipes and radiators are heating up around the vehicle.
If this does not help, you can try the following method:Single-axle caravan: Switch o the circulation pump.
Tilt the caravan forwards. Leave it in this position for a few minutes to allow the air to travel upwards in the
system. Open the bleed screw located at the highest point. Leave it open until glycol fluid comes out. Pro-
ceed in the same manner but with the caravan tilted backwards. Then position the caravan horizontally and
start the circulation pump. See if the pipes and radiators are heating up around the vehicle.
Motorhome or twin-axle caravan: For these, the easiest way to bleed the system is to park the vehicle on
sloping ground or to raise one end of the vehicle using a jack. Bleed the system as described above.
NB. Ensure that the system is bled properly. Use the air bleed valves that are located throughout the system.
Risk of overheating if the system is not properly bled.

13. IMPORTANT INFORMATION
• Always switch o the 12 V main switch for the boiler when the vehicle is not in use.
• When washing the vehicle, do not spray water directly towards the flue.
• When camping in winter conditions, ensure the flue and exhaust air valves are kept clear of snow and ice.
• The vehicle may be heated even if the hot water heater is not filled with freshwater.
• The LPG boiler and electric elements may be operated simultaneously.
• Always renew the air cushion in the water heater after 10 days of use so as to create a new air cushion.
This can
be done by opening the safety/drain valve on the boiler for a few seconds.
The air cushion allows expansion to take place and protects the boiler against pressure impacts from
the freshwater pump.
• Always drain the hot water heater of freshwater when there is a risk of frost and when the
vehicle is not being used, otherwise there is a risk of serious frost damage.
• The LPG boiler must not be in operation when refuelling the vehicle or when filling
a fixed LPG tank.
• Never allow the heating system to stand empty of glycol fluid.
• The ethylene glycol mixture should be changed every other year, as certain properties such as corro-
sion protection deteriorate over time.
If Alde Premium Antifreeze is used, the interval for changing the mixture can be extended to five years
under normal operating conditions.
Omitting to change the fluid can result in frost damage, corrosion, bacterial growth and/or overheating.
• Sterilisation fluids for freshwater can cause harmful corrosion to the stainless structure of the boiler.
Always read the data label on additives that are used and make sure the system is flushed of all addi-
tives before you use the boiler.
• Hard water is water that has a high dissolved-mineral content, particularly calcium. If the boiler is used
in a hard water area for longer periods, install a water filter.
Hard water can lead to a build-up of lime scale that can reduce the functionality of the system.
NB. Close the main LPG valve in the following situations.
• When the vehicle is not intended to be used.
• The national legislation of the country you are in may require you to close the main LPG tap when the
vehicle is in trac.
• When repairing the boiler.
• When a leak in the LPG system is suspected.
