Would you be able to attach the results file from your simulation?

I tried simulating the file and it is working just fine, and heating energy use looks normal as well.I used Calgary weather data. I am not sure which one you used .. I think it was edmonton .. very close though.Cheers

Hi James,
Thank you for the reply.
I have transitioned the file to v5. However I still find that I am getting the same problem as before.
I have attached to updated idf file.

Dear Langdon.
The text “AHU HEATING COIL CONTROLLER” does not appear in your IDF, so I can’t figure out what is referred to by the error. In addition, the IDF is difficult to read because of the many interspersed comments.
I recommend that you begin using the newest version, so it can be opened by the IDF Editor. Transition of your IDF to the current version is almost a one click affair!

Subject: [EnergyPlus_Support] Large Reheat Consumption During Summer
Hello,
I am running multiple simulations using various building configurations and I have run into the problem in my results which I can't determine the cause for.
I get low natural gas consumption in the winter months and high consumption during the summer due to the reheat system. I am using an old version of EnergyPlus which I hope is not a problem.
I do get a Severe error in my simulations which occurs multiple times:
Severe ** Controller error for controller = AHU HEATING COIL CONTROLLER
** ~~~ ** Occurrence info=EDMONTON STONY PLAIN AB CAN WYEC2-B-25145 WMO#=711230, 08/06 04:02 - 04:03
** ~~~ ** Controller function is inconsistent with user specified controller action = "" action
** ~~~ ** Actuator will be set to minimum action
** ~~~ ** Note: Chilled water coils should be reverse action and the entering chilled
** ~~~ ** water temperature should be below the setpoint
** ~~~ ** Note: Hot water coils should be normal action and the entering hot
** ~~~ ** water temperature should be above the setpoint
I have attached the simulation file I am working with and the weather file.
Thank you for your help.
