When setting the cooling schedule, it is found that the seasonal schedule does not work, while the heating schedule works,

Actually, I have an update and I figured out what is going on. There’s no bug in EnergyPlus or OpenStudio.

It’s just that the summer design day schedule of the Seasonal Schedule is set using the _base_schedule. And, in your case, the base schedule is a 50C cooling setpoint:

So your cooling system is effectively sized to zero since there’s no cooling demand when the thermostat setpoint is at 50C.

An easy way to address this is just by flipping the _base_schedule and the _season_scheds like so:

But, given that I can see how this case confused me, I think I will also add optional inputs for _summer_des_ and _winter_des_ schedules to the “HB Seasonal Schedule” component. This way, you’ll always be able to override whatever design day schedules are set from the _base_schedule. I’ll post back here once it is implemented.
