Re: [EnergyPlus_Support] No Temperature Control

["Michael J. Witte" <mjwitte@xxxxxxxx>]

1.  SET POINT MANAGER:SINGLE ZONE MAX HUM is placing a set point on node "AHU1 
Humidifier Outlet Node", but the cooling coil contoller's control node is "AHU1 
Fan Outlet Node".  The max hum set point must be place on the same node "AHU1 
Fan Outlet Node".

2.  SINGLE DUCT:VAV:NOREHEAT will not modulate the air volume flow rate to the 
zone for heating control.  It only controls for cooling.  If you want variable 
volume heating, then use SINGLE DUCT:VAV:REHEAT with Damper Heating Action set 
to Reverse Action.

I would suggest turning on report variables for "System Node Temp", "System 
Node Humidity Ratio", "System Node Setpoint Temp", "System Node Humidity Ratio 
Min", "System Node Humidity Ratio Max", and "System Node VolFlowRate" for key 
nodes in the system to observe how the system is responding to the controls.
