I'm simulating an office building using absorption chiller and an electric chiller at São Paulo - Brazil.
When I run the simulation, the .err file shows me an error like this:
** Warning ** SimHVAC: Maximum iterations (20) exceeded for all HVAC loops, at SAO_PAULO/CONGONHAS - BRA SWERA WMO#=837800, 01/01 00:00 - 00:15

What is the meaning of this error? How can I fix this problem? I've obtained the .svg file in this simulation and the loops appear to be ok. Could you help me please?
thank you very much
