Dear all,

In E+ 9.2.0, I'm trying to simulate a simple Data Center model which contains only ITE equipment in a zone.

The HVAC consists of Condenser Loop - Plant Loop (Chiller) - Air Loop - Zone

From this system, I would like to control the plant loop's pump mass flow rate [kg/s] and see how zone temperature changes.

Although I was able to control the pump mass flow rate by EMS, the zone temperature didn't change and stay at zone temperature setpoint.

To see the zone temperature variation by pump mass flow rate change, the zone SetpointManager must not operate.

Is there any methods to see the variation of zone temperature by controlling pump mass flow rate ignoring zone SetpointManager?

Any comments or suggestions will be very much appreciated.

Thank you for your time.

What about the fan? It may happen that the air flow rate compensates (increasing) the reduced water flow rate
