I am unable to tweak this error which I got while running for full year simulation. I have set one chiller feed to TES and TES to the Colling coil in the secondary Chilled water loop. I have set the Controller for water coil as
IDF,Controller:WaterCoil,Controller Water Coil 2,Temperature,Reverse,Flow,CC Air Outlet Node1,CC1 Water Inlet Node,Autosize,Autosize,0;
The error I am getting is
** Severe ** FindRootSimpleController: Controller error for controller = "CONTROLLER WATER COIL 2"
** ~~~ ** Environment=RUN PERIOD 1, at Simulation time=01/28 06:02 - 06:04
** ~~~ ** 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 = 15.82 [C]
** ~~~ ** Controller sensed temperature = 16.13 [C]
** ~~~ ** Controller actuator mass flow rate set to 3.09 [kg/s]
** ~~~ ** Controller actuator temperature = 16.13 [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

While I am still trying to understand the SimHVAC iteration fix based on the suggestions here https://unmethours.com/question/17449/simhvac-maximum-iterations-warnings/
