I just battled the same error, using a simple unitary system in each of seven air loops. Turns out I had 1) moved my weather file from where I thought it was and b) perhaps more importantly, forgotten to insert an air terminal (here: AirTerminal:SingleDuct:ConstantVolume:NoReheat) before each zone in the air loop. Was panicking there for a bit, but then remembered I had made that same omission a few times before.
