[EnergyPlus_Support] Re: Fan Coil Behavier.
Thank You Very Mutch for answaring Fred.
but if we trunk all the variables on the system side, sutch as flow and tmpreture, how can the system not respect this limites, in other words if i only have a certan instaled capacity the model wont reatch the zone setpoint.
Do you think that this problem could be overcome with a unit ventilator?
Thank you One Again

EP in the simulation during this hours changes the water flow in the coils, and tempreture diferance, so that it can meet the set point temperature, increasing the coils capacity and not corresponding to what really happens in the Building. Does anyone know why it does this? I´ve tried limiting the maximum and minimum water flow rates in the fan coil object without any successes.
