8. Mount Supply Air Temperature Sensor
The Supply Air Temperature (SAT) Sensor must be mounted a
minimum of 8” above the edge of the supply duct (additional distance
is preferred when possible). Locate the SAT Sensor in an area of the
discharge air duct where less air turbulence is expected. Avoid dead
air areas where representative discharge air temperatures may not
exist.
The plug on the SAT Sensor harness plugs directly onto the AHC
Board. Refer to the figure in Step 7, Table 14.
Note: Supply Air Temp Sensor (SAT) is used in Link Communicating
mode and is optional in 24 volt mode.
Note: Supply Air Temp Sensor (SAT) ships with SC360 System
Controller.
Note: Supply Air Sensor kit is BAYSENSC360.

Table 15. Low Voltage Maximum Wire Length
The Low Voltage Maximum Wire Length table
defines the size and combined total maximum
length of the low voltage wiring from the
outdoor unit, to the indoor unit, and to the
thermostat.
Note: The use of color coded low voltage wire
is recommended to simplify
connections between the outdoor unit,
the control, and the indoor unit.
