What does ZONE-07 mean?
The unoccupied cooling and heating setpoints are within a few degrees of the occupied ones — the zone is kept at comfort conditions overnight and at weekends.
Why does it matter?
Unoccupied hours are two-thirds of the week; a 5–10 °F setback typically cuts unoccupied HVAC energy by 20–40 %.
What should you do?
Set unoccupied setpoints to about 80 °F cooling / 60 °F heating with optimal-start recovery, and confirm the occupancy schedule matches how the space is used.
