OpenStudio Application: Turning on/off heating and cooling in specific time periods

edit

I am using DOE Measures to add HVAC Systems. However, I have to modify the heating and cooling schedules. In the building I'm working on heating is turned on from 01/01-03/31, 09/01-12/31, and turned off from 04/01-08/31. And cooling is the opposite where turned off from 01/01-03/31, 09/01-12/31 and turned on from 04/01-08/31.

Right now I set up the temperature schedule for heating using two priority dates (01/01-03/31 and 09/01-12/31) and the default value below the summer design day temperature. The cooling temperature schedule uses one priority date (04/01-08/31) and the default value above the winter design day temperature. However, the model still turns on cooling during winter and heating during summer. These values are really small but I would like them to be completely shut off. How do I do this?

Hope the question is not confusing. Thank you in advance.
