Severe Error: FindRootSimpleController: Controller error for controller
Hello, I am conducting a simulation for a building that has a water-cooled chiller air conditioning system with a central chilled water plant, and heating by electric resistance. The system has one VAV per floor. When I finish the simulation, the following error appears for all of my VAV systems. I would like to understand why this error is being generated and what I need to review in the simulation. I am using EnergyPlus version 24.1.0.
** Severe ** FindRootSimpleController: Controller error for controller = "2 PAV COOLING COIL CONTROLLER"
** ~~~ ** Environment=RUN PERIOD 1, at Simulation time=04/20 06:02 - 06:03
** ~~~ ** Controller function is inconsistent with user specified controller action = Reverse action
** ~~~ ** Actuator will be set to maximum action
** ~~~ ** Controller control type=Temperature
** ~~~ ** Controller temperature setpoint = 17.65 [C]
** ~~~ ** Controller sensed temperature = 19.46 [C]
** ~~~ ** Controller actuator mass flow rate set to 12.43 [kg/s]
** ~~~ ** Controller actuator temperature = 19.46 [C]
** ~~~ ** The entering chilled water temperature (controller actuator temperature) should be below the setpoint temperature.
Thank you
