9. Error messages
When an error message appears on the Control panel, the LED on the On/Off button changes to red.
Connector failure: Check the red cable between the boiler and the panel and its red connectors.
Also check cables connected to the black connector of the boiler, e.g. cable between AC or iNet box
and boiler or panel.
Heater not found: There is a connection fault between the boiler and the control panel. Most likely a
problem with the boiler circuit board; contact your dealer. The fault may also be due to incompatible
software in the boiler and panel.
Overheat glycol: This fault can occur if the boiler is running at high power while there are air pockets
in the system; ventilate the heating system properly. Also check that the fluid level in the expansion
vessel is at least 1 cm above the MIN mark when the fluid is cold. It can also occur if the circulation
pump has broken or is disconnected from the boiler. To restore the fault, the glycol temperature must
drop to below 50°C. Once this happens, remove, then reconnect 12 V to the boiler.
Overheat lockout: There has been an episode of overheating in the boiler. The temperature has gone
down but the boiler is still locked. To reset the fault, disconnect, then reconnect, 12 V to the boiler.
Overheat PCB: Overheating in the boiler or boiler compartment. To reset the error, the temperature
in the pan must first drop. Disconnect, then reconnect 12 V to the boiler. If this does not help, contact
Alde Service Partner.
Heater failure: The circuit board is damaged. To reset the fault, disconnect, then reconnect 12 V to
the boiler. If the error persists, contact Alde Service Partner.
Low battery voltage: If the vehicle's battery voltage to the boiler is less than 10.8 V, the boiler stops.
This resets automatically when the voltage reaches 11 V. If the voltage is lower, other error messages
may also appear. These error messages occur only because the battery voltage is/has been too
low and are therefore not true malfunctions. Ensure that the boiler gets the right voltage for the right
function.
Gas failure: Ensure that gas is available to the boiler. To reset the fault, disconnect and reconnect the
12 V supply to the boiler. When the supply is reconnected, gas operation must be reactivated in the
control panel. The fault may also be due to a defective spark generator and/or burner; contact Alde
Service Partner if the fault persists.
Fan failure: The combustion fan is defective. Contact Alde Service Partner.
Window open: A window switch indicates that a window near the wall flue is open, the boiler stops
running on gas. Gas operation restarts when the window is closed. Electric operation still works.
Panel failure: May occur if the panel has been exposed to high humidity for a long time. Make sure
the panel is dried, then restart. If the error persists, contact Alde Service Partner.
Opt. dongle not found: A previously identified option card is missing from the boiler. Make sure it is
connected or uninstall the accessories that require it. In order for the system to find the option card
again, disconnect 12 V from the boiler, plug in the option card, and then reconnect 12 V. If the error
persists, contact Alde Service Partner.
Load monitor not found: A previously identified load monitor is missing from the boiler. It is either
disconnected or defective. Make sure that the load monitor is plugged in; if the fault persists even
though the load monitor is plugged in, contact Alde Service Partner.
Zone 1 sensor error/ Zone 2 sensor error: The room sensor in zone 1 or zone 2, e.g. by sofa or bed,
is disconnected or defective. Check that the sensor is plugged in and that neither the sensor nor the
cable is defective. If the error persists, contact Alde Service Partner.
Hot water sensor error: The hot water sensor is disconnected or defective. If the error persists,
contact Alde Service Partner. The boiler continues to work but does not actively produce hot water;
however, the water can still get hot if the boiler produces heat.
