Severe Error: Unit heater air outlet node name must be the same as a zone inlet node name

edit

Hello I am new to using the software and am stuck on on this issue of finding the nodes and changing the names

here is the full error message

Severe * ZoneHVAC:UnitHeater = "UH_2". Unit heater air inlet node name must be the same as a zone exhaust node name. * ~~~ * ..Zone exhaust node name is specified in ZoneHVAC:EquipmentConnections object. * ~~~ ** ..Unit heater air inlet node name = NODE 886

Any help would be greatly appreciated
