MAN TGX Night Heater Question?

chaversdad:
What temps it set at? To keep it on all night it would need to be set to max, mines at 22c and that just keeps it right

Set at max. But even at that setting, it’s barely blowing with any ‘force’ (bit of a second question coming) - you could probably ■■■■ with more force that the blower.

In an identical truck I nighted out in ages ago, when it was set at 21, it was still way too hot!

So, to the second part of the question…

Does the night heater blower have a kind of high and low fan speed setting? Controlled by maybe a relay?
