[Bldg-sim] eQuest - FCU - how to make it cycle

[Yuvaraj Saravanan]

Hi All,
Does anyone know how to make a FCU cycle ON/OFF based on the zone
thermostat setting? I tried choosing the "Fan on mode" to be
intermittent in the Fan->Flow parameters tab. When I make the fan to be
intermittent, fan is cycling but the supply CFM is no more a constant
volume. It is varying the supply CFM. I observed this in the hourly
report.

ASHRAE standard 90.1 requires the fan to cycle to meet the loads during
unoccupied hours. How everybody model this in eQuest when you have a FCU
system?

Any suggestions is greatly appreciated.

Regards,
Yuvaraj
