The contractor loaded the software update on Monday. The only change in the display is that it now shows Total KWh in addition to Avg. Heat KWh and Run Hours. Havent had a chance to monitor the Monthly Total. Before update, it was clearly reporting this number incorrectly. After reading Josephparris post above, I am wondering whether I have the correct update or not ?? My HVAC contractor is none too happy about having to update 30 units they have in the field.
