Functions marked with a (*) are accessories, which are not installed on all vehicles,
refer to the vehicle manufacturer’s instructions.

2:13 ERROR MESSAGES
Low battery: If the vehicle has a battery voltage of less than 10.8 V, the boiler will stop. This is reset automatically
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 ame. 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. Also check that the uid level in the expansion tank is at least 1 cm above the
min line when cool.
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.
Most probably a problem with
the heater’s circuit board.
3rd Part Panel C. fail: Communication fault between Alde’s panel and Alde Smart Control*.
Panel failure: Fault on the panel. May be caused by excessive moisture.
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.
To reset some of the errors and restart, switch off the boiler from the panel, disconnect 230 V to the vehicle and
disconnect 12 V from the boiler.

4/4
The functions that are checked under Installed func-
tions (see section 2:15) will not be affected by a reset. A
reset will also cancel error messages in the error log.
2:14 RESETTING
Pressing Reset resets the panel to its factory settings. After resetting, the panel will be set as follows: Boiler – Off
mode; electrical operation – 1 kW; LPG heating – On mode; indoor temperature – 22°C. Other functions are switched
off.
iNet connection fail: Cannot nd 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.
Functions marked with a (*) are accessories, which are not installed on all vehicles,
