Webasto Air Top 2000

Hi all
Heater is trying to start, fan blows but doesn't ignite then stops. I only have got a basic on off control, the green light flashes 5 times quickly the 9 times slowly and repeats.
Anyone had the same, knows what the sequence of lights us indicating?
Cheers all.

My air top 2000 needs a really healthy 12v supply to start it (It takes a high current during the start up sequence).
As said, run the engine at a fast idle to ensure the battery is at full capacity, then try again.
Your problem may also be a poorly battery.
