Hi Waseem,
Your question is a bit unclear. Having look into your EMS code (based on temperatures 6C and 3C) it seems you would like to control a chiller leaving temperature (chilled water stream which goes to a building) rather than a condenser loop (connecting a chiller's condenser and a cooling tower) which temperature is higher.
The best way to control a chilled water temperature is to modify the SetpointManager:Scheduled, CHW Loop Setpoint Manager. The schedule 40 (6C all the time) is assigned to this object and it can be modulated by EMS.
Supply air temperature is also controlled by a SetpointManager, in your case "warmest" for controlling cooling and "coldest" for controlling heating. You can try to overwrite them by EMS as well, or to change them to a constant temperature (SetpointManager:Scheduled) and assign desired values by EMS.
Cheers, IK
