**  ~~~  ** Controller sensed temperature = 16.65 [C], considerably higher than the 12.4C setpoint? Is your chiller and pump working?
ÂOne of idf model I am working is showing me the Controller error as bellow for all the VAV Cooling coil controller
** Severe  ** FindRootSimpleController: Controller error for controller = "VAV_1_COOLC_CONTROLLER"
  **  ~~~  **  Environment=ANNUAL, at Simulation time=01/27 18:40 - 18:50
  **  ~~~  **  Controller function is inconsistent with user specified controller action = "" action
  **  ~~~  **  Actuator will be set to maximum action
  **  ~~~  ** Controller control type=Temperature
  **  ~~~  ** Controller temperature setpoint = 12.40 [C]
  **  ~~~  ** Controller sensed temperature = 16.65 [C]
  **  ~~~  ** Controller actuator mass flow rate set to 10.87 [kg/s]
  **  ~~~  ** Controller actuator temperature = 16.67 [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 have set the ChilledWater coils to reverse action and my Controller is using setpointmanager as
SetpointManager:MixedAir,
  VAV_1_CoolC SAT Manager, !- Name
  Temperature,       !- Control Variable
  VAV_1 Supply Equipment Outlet Node,  !- Reference Setpoint Node Name
  VAV_1_HeatC-VAV_1_FanNode,  !- Fan Inlet Node Name
  VAV_1 Supply Equipment Outlet Node,  !- Fan Outlet Node Name
  VAV_1_CoolC-VAV_1_HeatCNode;  !- Setpoint Node or NodeList Name
*************  ** Severe  ** FindRootSimpleController: Previous controller action error continues for controller = VAV_1_COOLC_CONTROLLER
  *************  **  ~~~  **  This error occurred 11 total times;
  *************  **  ~~~  **  during Warmup 0 times;
  *************  **  ~~~  **  during Sizing 0 times.
I get 48 of these warnings with year of simulation. Can this be ignored safely considering only 12 times in a year for each controller.

For breaking the natural law, there are natural penalties:
Those who live by knives die by them. Those who betray their friends lose them. Those who abandon their children never know the sweetness of their kiss. Those who travel from bed to bed lose the capacity for trust. Those who torture their consciences are tortured by them in return. Those who refuse the one in whose Image they are made live as strangers to themselves.
