[EnergyPlus_Support] Node errors
I get the following errors after simulating my idf file:

I am guessing the node errors are to blame for the tolerance failures afterwards. But i cannot understand what i am doing wrong (first time user of E+). Any help in solving my problem will be greatly appreciated.
