Indoor Temperature Averaging
The LC has the ability to average all of the zone
temperature sensors connected to the LC and the
return air temperature sensors connected to the wall-
mount unit, use only the zone temperature sensors, or
use the LC sensors and any unit which has its blower
run continuously. This can be set differently for each
zone. This value will then be used as a zone indoor
temperature for the LC and wall-mount unit control
functions.
There are three possible sensor averaging selections:
• LC Only
This configuration only averages the zone
temperature sensors connected to the LC and
enabled within the specific zone.
• Blower On
This configuration averages any temperature
sensors connected to the LC that are enabled and
the return air temperature sensor of any wall-
mount unit set to run in continuous blower within
the specific zone.
• All Sensors
This configuration averages the zone temperature
sensors connected to the LC that are enabled and
all the return air temperature sensors of all wall-
mount units within the specific zone, regardless of
blower operation.
