Heater Fan on Permanent Supply (1 Viewer)

[Jasz]

A warning for Imala owners and maybe other models. It appears that the heater fan is deliberately taken from the permanent supply fuse of the Sergeant controller and not the fan fuse. After the last two habitation services the fan has been left on, the first time we didn't notice and put it back in storage - this then proceeded to drain the battery (fortunately the controller switched it off before the battery got too low).
Auto-Trail said this is so it can be used in transit, but it's something to be aware of!

Surely it should be controlled by the electronics in the Truma boiler.

The heater fans on the newer version or our van stay on if you switch the main switch off. This is to cool the heater down so it won't trip on over temperature. Ours does trip but I'm glad it's wired this way so there's no standby drain. We never use the heating anyway

Ours is 2016, the fan can be switched off manually anyway so yours is obviously more advanced.
I can't really see why you would want to use the heater while traveling anyway, I would rather it was on the fan fuse.
