Why do I get 'Cooling Design Supply Air Temperature=[25.00]' and 'Heating Design Supply Air Temperature=[20.00]' severe errors? ?

edit

My understanding is that I am setting the heating and cooling temperature setpoints. For instance, if the thermal zone is at 25C or hotter it will cool. My understanding maybe incorrect here.

The error I received in the eplusout.err file is the following:

Cooling Design Supply Air Temperature=[25.00]
**   ~~~   ** This is not allowed.  Please check and revise your input.
** Severe  ** Sizing:Zone="TZ - S6 - FCU 2" has invalid data.
**   ~~~   ** ... incorrect Zone Heating Design Supply Air Temperature=[20.00] is less than Zone Cooling Design Supply Air Temperature=[25.00]

How should I resolve this issue? I changed the temperature setpoints but the issue persists.
