EnergyPlus AirLoopHVAC:UnitarySystem: "SetPoint" vs "Load" control type

I am modifying in EnergyPlus a simplified 1-zone model, changing the control type of the UnitarySystem.

I am attaching 2 pictures for 1 day in July.

The starting model has a control type (second field of the unitary system) set to "Load". The zone temperature is always maintained within the setpoints, the heating coil and the cooling coil work fine (first picture).

When I change the control type to "SetPoint", the zone temperature is not controlled anymore, it gets quite high, and the cooling coil does not even turn on. I added a SetpointManager:SingleZone:Cooling and a SetpointManager:SingleZone:Heating, but nothing happens. I switched to SetpointManager:MixedAir, but same story.

Here is the complete model: https://drive.google.com/file/d/1clKeAdFswo3yNuYm2voBn1ZjcPcwHgwx/view?usp=sharing

What knobs should I play with to make the model work, when I change from Load to SetPoint?

"Load" control type "SetPoint" control type
