Quick tip for those who spend time on bays without keys. If you hold the blower switch round to p while turning the ignition off you can then use the blowers with the engine off and keys out.
But no aircon (unless it also allows you to run the engine…)
Cue a flat battery if stick on the bay got a while?!
*for ^
No aircon just the blower to get sone air circulating, scania told me it cuts itself off if the battery gets too low, wouldn’t want to risk running it for hours myself though.
I believe it will run for 8 hours, when I tried it in my Scania it just blew out warm air hence I never used it 
There’s no ‘p’ on my blower switch. Is this because I have the base spec G cab?!

Not seen one on our R440 highlines either…?
Used to find some night heaters turned down will run the fan to circulate air.
You need climate control for this.
Mines got it, always wondered what it was for. R series luxury spec tho
