                      I can't answer your question, but only relate that
                      I had a similar experience.<br>
                      <br>
                      An early Magnum MS4448AE would not reliably start
                      and run a modern hydronic boiler in an off grid
                      home. I had opened a case with Magnum tech
                      support, but the frustrated HVAC contractor pulled
                      the unit and installed a different brand of boiler
                      and the problem disappeared.<span
                        class="Apple-converted-space"> </span><br>
                      <br>
                      In my own home my MS4024AE has nothing it won't
                      run, and it's a newer unit. But whether that's
                      coincidental or the result of an inverter firmware
                      or hardware upgrade, I can't say. Maybe Gary
                      Baxter can?<br>
