2107 Logomatic

Furgas Member Posts: 1
Hello all,
I have lost power and wondering how to wire my Buderus 2107 Logomatic through a extenson cord plugged into a generator? I disconnected L1 and L2 to avoid smoking the control and tapped into the service switch at the boiler.
I have 120 v between L1 and neuterual but nothing from L1 to L2.

    I wouldn't do that. How clean is the power coming from the generator? At the very least you should plug it into and run it thru a UPS.
    Better would be to have an electrician handle it.

    There was an error rendering this rich post.

    There isn’t an L2 on that control, where are you seeing that? Are you good with basic electrical? Hope you get your heat back soon

    The 2107 doesn't like square wave power that's produced by non inverter generators.
