Hi all, Apologies because this question has been asked before........ but I just don't exactly know what is the problem with the following severe error: (please note that I have a VAV with two setpoint managers...one single zone cooling and another one single zone heating) The simulation can still run.

* Severe * FindRootSimpleController: Controller error for controller = "AIR LOOP 8 AHU COOLING COIL CONTROLLER" * ~~~ * Environment=HEAVYWEIGHTNCC2016 (01-01:31-12), at Simulation time=03/30 06:06 - 06:09 * ~~~ * 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 = 8.57 [C] * ~~~ * Controller sensed temperature = 9.30 [C] * ~~~ * Controller actuator mass flow rate set to 66.53 [kg/s] * ~~~ * Controller actuator temperature = 9.36 [C] * ~~~ * Note: Chilled water coils should be reverse action and the entering chilled * ~~~ * water temperature (controller actuator temperature) should be below the setpoint temperature * ~~~ * Note: Hot water coils should be normal action and the entering hot * ~~~ * water temperature (controller actuator temperature) should be above the setpoint temperature * Severe * FindRootSimpleController: Controller error for controller = "AIR LOOP AHU COOLING COIL CONTROLLER"

Thanks a lot for your help,
