Table 29 — Color Code Recommendations
Connect the CCN (+) lead (typically RED) to the unit’s
TB1-12 terminal. Connect the CCN (ground) lead
(typically WHT) to the unit’s TB1-14 terminal. Connect the
CCN (-) lead (typically BLK) to the unit’s TB1-16 terminal.

RTU OPEN CONTROL SYSTEM — The RTU Open con-
trol is factory-mounted in the 48TC unit’s main control box, to
the left of the CTB. See Fig. 64. Factory wiring is completed
through harnesses connected to the CTB. Field connections for
RTU Open sensors will be made at the Phoenix connectors on
the RTU Open board. The factory-installed RTU Open control
includes the supply-air temperature (SAT) sensor. The outdoor
air temperature (OAT) sensor is included in the FIOP/accesso-
ry EconoMi$er2 package.
The RTU Open controller is an integrated component of the
Carrier rooftop unit. Its internal application programming pro-
vides optimum performance and energy efficiency. RTU Open
enables the unit to run in 100% stand-alone control mode, Car-
rier’s i-Vu

Open network, or a third party building automation
system (BAS). On-board DIP switches allow you to select your
protocol (and baud rate) of choice among the four most popular
protocols in use today: BACnet

Refer to Table 30, RTU Open Controller Inputs and Outputs
for locations of all connections to the RTU Open board.
