After simulation in error log I see this error
** Severe ** Node Connection Error, Node="NODE 105", ZoneInlet node did not find an outlet node.
** ~~~ ** Reference Object=ZONEHVAC:EQUIPMENTCONNECTIONS, Name=KOTLOWNIA
** Severe ** Node Connection Error, Node="NODE 77", ZoneExhaust node did not find a matching inlet node.
** ~~~ ** Reference Object=ZONEHVAC:EQUIPMENTCONNECTIONS, Name=KOTLOWNIA
************* There were 2 node connection errors noted.
I thought it's because I tried modeling radiant ceiling and some time ago I removed panels from KOTLOWNIA zone, but I deleted old water loop (both heating and cooling loop) but still error exists. There's none of the radiant panels left in Thermal Zone whatsoever. I have no idea what to do or where to delete it.
