[EnergyPlus_Support] Control of AirTerminal:SingleDuct:VAV:Reheat - Sizing Problem [1 Attachment]

["Javed Iqbal eee.javed@xxxxxxxxx [EnergyPlus_Support]" <EnergyPlus_Support@xxxxxxxxxxxxxxx>]

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,
