If Box Heating and Supplemental Heating are selected in the Coils (VAV-SD) configuration section, the Heating Priority selections are enabled to determine the sequencing. A configuration input to the VAV-ZN-T Sequencing (Occupied Zone Sequencing (VAV) v51), WarmupCooldown Sequencing, and the VAV-Unocc Status Determination (Unoccupied Sequencing (VAV)) modules are set to match the selected choice.

Select the Box Heating used first option if you want the box reheat coil to be commanded to 100% before the supplemental coil is used.

Select the Supplemental Heating used first option if you want the supplemental coil to be commanded to 100% before the box reheat coil is used.
