Why the zone air temperature is constant

Hello my friends, i have created a buidling model equipped with a VRF system. The sone setpoint temperature is 20oC, and the zone air temperature is constantly 20oC throughout the simulation as expected. But in reality, the zone air temperature should fluctuate around 20oC,like 21-23oC due yo the on/off control of the air terminal. So how can i configure my VRF system, so that the temperature changes in the zone is like the real situaton? Many thanks!

Why is it important for you to see the thermostat temperature differential reflected in your model?

Hi, Shorowit, The thermostat differential is not so important for the energy consumption, but i want to make the simulation result of the zone air temperature looks more realistic. Not sure there are some setting on the thermostat to make it possible?
