Hi, all.
I am trying to build two systems: 1) a single-stage heat pump system with on/off cycling fan. 2) a single-stage heat pump system with descrete fan (2 speeds).
An UnitarySystem was used including DX cooling and heating coils. I hvae set the Supply Air Fan Operating Mode Schedule Name to Always 0 to combine the fan and coil's operation into cycling mode.
The problem is, when I look at the output(system node mass flow rate on zone inlet node), The airflow rate seems like variable air volume fan. It does not show on/off cycling pattern or 2 levels of flow rate.
Can anyone could give me an advise?
