To get heating to simulate properly with a VAV system, the thermostat needs to be defined as reverse acting.

<p class="MsoNormal"><span style="color:#44546a">First thing that jumps out at me is that there is no Heating Discharge Air Tempertaures or Reheat Temperatures set on the System>Heating Tab (last image you shared). For a VAV System I’d expect these values to
be something like: Zone Max Temp: 90F Hot Deck Max Leaving Temperature 60F and Reheat Delta T: 35F.

<p class="MsoNormal">My model is located in Mexico and three zones are equipped with VFD. So I selected Pkgd Var Vol + Heat pump for these three zones and set the system up by the design cooling and heating capabilities. Currently, the SS-R shows 4380 under
heated hours for each of the zones. And no space heat is provided for any of the zones. Does anyone know the possible reasons for this phenomenon?<u></u><u></u></p>
