Hi, 
I have a problem in simulation studio. I want to cool a zone by varying the airflow (fan: type 744 with a PID: type 23). The air input in the fan is at a temperature of 13°C And I have put a negative gain in my PID. When I launch the simulation and the zone temperature reach the set point the fan start to blow but instead of cool my zone the flow rate increase the temperature! Does anybody understand where I have made a mistake?
Kind regards
Guy THOMAS
