I have?another question about using Trane Trace 700. I hope someone on the list can point me a direction. ? I am trying to determine the heating load of?Transformer room and Loading Dock. ? Transformer room 245 ft, 9' 10 height Ventilation = 1500 cfm (OA) @ -10 F Room Exhaust = 1500 cfm ? Loading 328 ft, 19' 10 height Ventilation 650 cfm (OA) @ -10 F Room Exhaust = 650 cfm ? I select the unit heater as the system.? ? I input cfm under ventiltation heating ? When I looked at the system checksum, I did not see any ventilation load. What did I miss? ? Many Thanks, ? Francis?
