Since it is during the sun rise time in Winter, there may be a mode change (heating and cooling) involved.
Cannot tell without the IDF.

Dear Forum,
I started to model the VRV HVAC Terminal Unit, and I have received many warnings as this one:
Warning ** ZoneHVAC:TerminalUnit:VariableRefrigerantFlow "TU2 COMEDOR"
** ~~~ ** Iteration limit exceeded calculating terminal unit part-load ratio, maximum iterations = 500
** ~~~ ** Part-load ratio returned = 6.291E-003 Environment=NESTLE CHIAPA DE CORZO, at Simulation time=01/02 06:00 - 06:10
** ~~~ ** Load requested = -0.12331, Load delivered = 3.54534E-016
I do not know the reason of it, but I think it is necessary to solve it in order to trust the results of the simulation.
Any advice greatly appreciated!
