RTU--OPEN CONTROL SYSTEM
RTU--Open Controller
The RTU--OPEN controller is an integrated component of
the Carrier 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, Carrier’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, Modbus, Johnson N2 and
LonWorks. (See Fig. 56.)
Carrier’s diagnostic display tools such as Field Assistant
BACview6 Handheld or Virtual BACview can be used
with the RTU--OPEN controller. Access is available via a
5--pin J12 access port.
SENSORY/ACCESSORY INSTALLATION
There are a variety of sensors and accessories available
for the RTU-OPEN. Some of these can be factory or field
installed, while others are only field installable. The
RTU-OPEN controller can also require connection to a
building network system or building zoning system. All
field control wiring that connects to the RTU-OPEN must
be routed through the raceway built into the corner post of
the unit or secured to the unit control box with electrical
conduit. The unit raceway provides the UL required
clearance between high and low-voltage wiring. Pass the
control wires through the hole provided in the corner post,
then feed the wires thorough the raceway to the
RTU-OPEN. Connect the wires to the removable Phoenix
connectors and then reconnect the connectors to the board.
See Fig. 56.
IMPORTANT
: Refer to the specific sensor or accessory
instructions for its proper installation and for rooftop unit
installation refer to base unit installation instructions and
the unit’s wiring diagrams.
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal
injury, death and/or equipment damage.
Disconnect all electrical power to the unit and use
appropriate Lock--out/Tagout procedures before wiring
the RTU--OPEN controller.
