Ah yes I think it was that field I was referring too. Shame that didn't work. That was normally the trick for us!

Are you talking about 'Field: Damper Heating Action'? If yes, I tried all the three controls, Normal, Reverse and ReversewithLimits but not improvement.
Thank you

Hi
I know this problem well, but I can't open an idf right now to give you the exact solution, there is a something around the bottom of the object AirTerminal:SingleDuct:VAV:Reheat which turns on and off the reheat coil. Sorry I can't be more precise right now fiddle around with this object and it will suddenly magically turn on

Subject: [EnergyPlus_Support] Control of AirTerminal:SingleDuct:VAV:Reheat - Sizing Problem [1 Attachment] Dear All,
I assigned a typical VAV system (Baseline System 5) with reheat but there are many heating unmet hours in the zones served by the system. I did most of the quality checks (correct OA, zone setpoints, zone and system sizing etc.) to see where the problem lies. And i found ' AirTerminal:SingleDuct:VAV:Reheat' is NOT active or sizing is zero in HTML report. To further ascertain the cause of the problem, I plotted temperatures [ see attachment] at all the nodes to see the temperature regime. This also shows that reheat coil doesn't raise the air temperature to meet the room set-point.
This is being simulated for CZ5A.
I also tried to look out for some solutions discussed here [ LINK LINK ] but unfortunately nothing works for me.
I would appreciate any help in this regard.
Thank you,--
