Hi to everyone I've just installed one of these heaters in my defender 110 amazing heat had to rebuild it as it's one with it's own diesel tank attached. And when delivered had been dropped from a high height. But am wondering if the led screen is meant to be on all the time? It turns it self of from running when I use the key fob or turn of from unit but a little worried it's going to be a drain on my leasure battery. I'm using 2 one for start up and other runs everything else.
