I am encountering this error when running my simulation in OpenStudio:

* Severe * FindRootSimpleController: Controller error for controller = "CONTROLLER WATER COIL 5"

* ~~~ * Environment=OMAHA EPPLEY AIRFIELD ANN CLG .4% CONDNS DB=>MWB, at Simulation time=07/21 00:00 - 00:10

* ~~~ * 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 = 18.00 [C]

* ~~~ * Controller sensed temperature = 35.72 [C]

* ~~~ * Controller actuator mass flow rate set to 10.09 [kg/s]

* ~~~ * Controller actuator temperature = 35.79 [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

I am encountering this error for every coil that I have. The entering water temperatures for the heating coil and cooling coil are 170F and 42F respectively. The setpoint temperature is 60F for Cooling and 100F for Heating. Also note that 3/5 of my systems are dual duct systems, while the other two are single duct VAV systems. Also, I am using District Heating and Cooling due to the fact that I am looking at a single university building being served by a central plant; therefore, I have no Condenser Water Loop. Any idea as to what is causing these errors? Also, thoughts on not including the Condenser Water Loop?
