Dear colleagues,
I would like to know if any of you ran into the following:
My model worked fine in version 8.2.0 and when updated to version 8.3.0 it generated many severe errors all of them associated with Cooling Coil Control Logic (
Controller:WaterCoil,
AHU CC Control, !- Name
Temperature, !- Control Variable
Reverse, !- Action
Flow, !- Actuator Variable
AHU CC Outlet, !- Sensor Node Name
AHU CC CW Inlet Node, !- Actuator Node Name
** Severe ** FindRootSimpleController: Controller error for controller = "AHU CC CONTROL"
** ~~~ ** Environment=PMVCHECK, at Simulation time=07/14 06:00 - 06:10
** ~~~ ** Controller function is inconsistent with user specified controller action = "" action
** ~~~ ** Actuator will be set to maximum action
** ~~~ ** Controller control type=Temperature
** ~~~ ** Controller temperature setpoint = 12.80 [C]
** ~~~ ** Controller sensed temperature = 26.41 [C]
** ~~~ ** Controller actuator mass flow rate set to 0.92 [kg/s]
** ~~~ ** Controller actuator temperature = 33.24 [C]
)
I put output variables on the actuator node name and cooling supply output node and got strange results in the form that chilled water temperature increases (up to 35oC), although SetPointManagers are set for these temperatures to be in range 6-10oC.
Any help is more than welcome.
P.S. With all these inputs, the version 8.2.0 was working fine and the setpointManagers were followed.
