Seasonal Schedule create

Hi all,
I’m trying to set a seasonal schedule,but I have a issue. I want to know,in honeybee, is it possible to run only the cooling system for a period of time? For example,from May 15th to September 15th, only the cooling system is operated.
And I have tried to create two seasonal schedules.
The first one successfully ran,but during the heating period, both heating load and cooling load appeared.
The second one get an error and I don’t understand what I’m doing wrong.

  1. The simulation has not run correctly because of this severe error:
    ** Severe ** ProcessScheduleInput: Schedule:Year=“COOLING-COOLING” has overlapping days in its schedule pointers

Kind regards!
