After-hours overrides can produce aggravated partial load conditions in both the heating and cooling modes. Aggravated partial load conditions are caused when you override a single zone for after-hours use. This usage causes the rooftop equipment to operate for one zone only. In a Verasys system, you can use a global override to trigger a group of zones. The system uses a global override method to operate with sufficient load to reduce cycling caused by light load conditions.
