Units Description
• Backup unoccupied cooling set
point.
• Used if the communications link
is lost for 5 minutes between the
CORE Unit Controller and network
°F
control panel. Used only in room
sensor applications.
• Set point temperature must be
greater than or equal to Parameter
138 plus Parameter 152).
