Sargent Power Supply Unit.

I thought that the little black press button on the unit was the master switch and completely cut all the power to the unit and therefore the caravan. However after using it to cut the power I checked the unit an hour later to see the battery charger and heating / hot water lights were still on / active. I’m assuming that this is normal and to cut the power to these two functions I need to cut the power at the distribution point / post?

When hooked to mains these will be on. The Black button prevents Battery run down when no mains supply is on the caravan
