I am using TYPE 928 (fan coil unit) for room heating, which gives me output of air temperature, humidity and mass flow rate to introduce into the building for heating during night time. meanwhile i need to use natural ventilation in daytime using TRNFLOW. It seems like that TRNFLOW is not working when I switch on the ventilation type or vice versa. what can i do to resolve this problem? in the real building i natural ventilation and fan coil unit are both working.
Thanks
