[EnergyPlus_Support] FindRootSimpleController: Controller error

["eplusven" <eplusven@xxxxxxxx>]

Hi all,

Could you please help how do i resolve this. Actually i wanted to model AHU air supply always 24C, becasue my Fancoil units will further does cooling or heating. For this reason I set the controller as 

SetpointManager:OutdoorAirReset,
    Supply Air Temp Manager 1,  !- Name
    Temperature,             !- Control Variable
    24,                      !- Setpoint at Outdoor Low Temperature {C}
    -9,                       !- Outdoor Low Temperature {C}
    24,                      !- Setpoint at Outdoor High Temperature {C}
    35,                      !- Outdoor High Temperature {C}
    Supply Air Temp Nodes 1; !- Setpoint Node or NodeList Name
This si giving problem only for one month i.e May. But rest of teh months the simulation going well with lot of warnings

   **   ~~~   **   Note: Chilled water coils should be reverse action and the entering chilled
   **   ~~~   **         water temperature (controller actuator temperature) should be below the setpoint temperature



Thanks
