down with the arrows. 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. To ack-
nowledge the fault and restart, disconnect the panel from the boiler and also pull out
the 230 V cable if *AC is connected together with Alde Compact 3020 HE.
Low battery: 12 V supply to boiler has dropped below 10.5 V, possibly causing sys-
tem brownout. Automatically clears when 12 V supply reaches 11 V.
Fan failure: Combustion fan speed too low. Bearing may be stiff after a period of
disuse. Automatically clears after 5 mins. Please try again.
Gas failure: Out of gas or gas is not igniting. Check the gas cylinder is full. Try a
different gas cylinder, ensuring it is propane gas. Check the gas regulator and any
isolation valves are open and not frozen
Overheat or red blue fail: Bleed the system of air. Check the uid level in the
expansion tank. It should be 1 cm above Min mark when cool. Check the circulation
pump is responding. Wait 15 mins for the uid to cool down.
Overheat PCB: Failsafe in boiler has triggered. Check the uid level in the expan-
sion tank. It should be 1 cm above the Min mark when cool. Check the boiler
compartment is ventilated, and that the vents are unobstructed. Do not place sto-
wage in the boiler compartment.
Window open: Optional window sensor has triggered, gas heating is suspended.
Automatically clears and gas heating resumes when window is closed.
Connection failure: Break in comms between Alde control panel and daisy-chained
third party control panel. Check the cable between the Alde control panel and third
party control panel.
Connection fail ext: Loose connection between Alde control panel and boiler.
Unplug cable at the control panel and boiler, then carefully plug back in. Check there
is slack on the cable at the control panel, but not excessive weight from free-hang-
ing/unmanaged cable
Panel failure 1 and 2: Moisture is trapped in the control panel. Remove the Alde
control panel from the vehicle and air in a warm, dry place overnight.
No match Heater/Panel: Control panel is incompatible with boiler PCB. Check
control panel part number. Control panel 3020-013 is for 3020 A-series boiler, 3020-
113 is for 3020 HE-series boiler.
