RTU Open Control System

The RTU Open control is factory--mounted in the 580J

unit’s main control box, to the right of the CTB. See

Fig. 36. 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/accessory EconoMi$er2 package.

The RTU Open controller is an integrated component of the

Bryant rooftop unit. Its internal application programming

provides optimum performance and energy efficiency. RTU

Open enables the unit to run in 100% stand--alone control

mode or to run 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, Modbus, Johnson

N2 and LonWorks. (See Fig. 37)

Refer to Table 5, RTU Open Controller Inputs and Outputs

for locations of all connections to the RTU Open board.
