Revision history [back]

I modelled a building using ideal air loads and no HVAC to obtain the loads. It ran fine and reported space heating as district heating. Then I turned off ideal air loads and added a gas boiler loop, AHU, zone heating, pumps, setpoint managers, .... I did all of the connections. I let all of the zone baseboards, AHU, boilers autosize for now. When I run it I now get fan, pimp and DX cooling electrical, but zero gas space heating. All of the heating is still reported as district energy. Am I missing a switch to turn off the district heating default? Running O/S 1.8.5
