2.1 - Control system
30RBS chillers and 30RQS heat pumps come with a SmartVuTM
control that serves as the user interface and conguration tool for
Carrier communicating devices.
SmartVuTM is an electronic control system used to regulate
the following types of units:
■30RBS air-cooled liquid chillers
■30RQS reversible heat pumps
SmartVuTM control can function as a stand-alone system or it may
be connected to the building management system using CCN
communication bus.
30RBS and 30RQS units may be tted with standard xed speed
fan control system or the optional variable speed fan drives which
can reduce the unit energy use during occupied and unoccupied
periods, provide condensing or evaporating pressure control and
smooth fan start.
For both 30RBS chillers and 30RQS heat pumps the system may
control xed speed pumps or variable speed pumps with a hydronic
module.
IMPORTANT: This document may refer to optional components
and certain functions, options or accessories may not be
available for the specic unit.

2.2 - System functionalities
The system controls the start-up of the compressors needed to
maintain the desired heat exchanger entering and leaving water
temperature. It constantly manages the operation of the fans in
order to maintain the correct refrigerant pressure in each circuit
and monitors safety devices that protect the unit against failure
and guarantee its optimal functioning.
SmartVuTM control system:
■Allows users to control the unit via the SmartVuTM user interface.
■Provides web connectivity technology.
■Supports Carrier Connect Services (Remote connectivity, alarm
notification, remote access, performance and operation
automatic reporting, technical advice).
■Supports Carrier Advanced Plant System Manager for multiple
chillers/heat pumps conguration.
■Provides direct BMS integration capabilities (RS485 / Ethernet)
2.3 - Operating modes
The control can operate in three independent modes:
■Local mode: The unit is controlled by commands from the user
interface.
■Remote mode: The unit is controlled by dry contacts.
■Network mode: The unit is controlled by network commands
(CCN / BACnet / Modbus). Data communication cable is used
to connect the unit to the CCN communication bus.
When the control operates autonomously (Local or Remote),
it retains all of its control capabilities but does not o󰀨er any of the
features of the Network.
Emergency stop! The Network emergency stop command
stops the unit regardless of its active operating type.

3 - HARDWARE DESCRIPTION
3.1 - Control boards
All boards making up the SmartVuTM control system are installed
inside the electrical cabinet. They communicate via an internal
LEN bus.
The system may embrace up to two SIOB boards, where the rst
board is used to manage all major inputs and outputs of the
controller, whereas the second SIOB board is used to support
either the compressor of circuit A or circuit B.
The rst SIOB board is also referred to as the main board – the
main board continuously monitors the information received from
various pressure and temperature probes and accordingly starts
the program that controls the unit.
At the same time, up to two (2) AUX1 boards can be installed. The
rst AUX1 board may provide additional inputs and outputs used
to monitor chiller water system cooling temperature (Master/Slave
assembly), leakage charge detection readings, electric heating or
boiler operation. This board is used only for smaller units (units
with only one fan) that have any of the aforementioned options
available (electric heaters, boiler, etc.).
The second AUX1 board is optional and it is used for units with
the dry cooler option. It provides information required to control
the free cooling cycle.
3.2 - Power supply to boards
All boards are supplied from a common 24 VAC supply referred
to earth. In the event of a power supply interrupt, the unit restarts
automatically without the need for an external command. However,
any faults active when the supply is interrupted are saved and
may in certain cases prevent a given circuit or the unit from
restarting.
CAUTION: Maintain correct polarity when connecting the power
supply to the boards, otherwise the boards may be damaged.
3.3 - Light emitting diodes
All boards continuously check and indicate the proper operation
of their electronic circuits. A light emitting diode (LED) lights on
each board when it is operating properly.
■ The red LED ashing for a two-second period indicates correct
operation. A di󰀨erent rate indicates a board or a software failure.
■ The green LED ashes continuously on all boards to show that
the board is communicating correctly over its internal bus (LEN
bus). If the green LED is not ashing, this indicates a LEN bus
wiring problem or a conguration issue.
3.4 - SmartVuTM connections
Connections are located on the bottom of the main controller.
■The control o󰀨ers communication protocols such as LEN, CCN
(Carrier Comfort Network), Modbus, or BACnet.
■It is possible to enable and disable end of line resistors via the
System menu (see section 5.6).
■One Ethernet port allows for TCP/IP communication or BMS
(Building Management System) connection.
3.5 - Pressure transducers
Three types of transducers (high pressure, low pressure, water
pressure) are used to measure various pressures in each circuit.
These transducers deliver 0 to 5 VDC. They are connected to the
SIOB board.
■Discharge pressure transducers (high pressure type)
These transducers measure the discharge pressure in each
circuit. They are used to control condensing pressure or high
pressure load shedding. Discharge pressure sensors are
mounted on the discharge line piping of each circuit.
■Suction pressure transducers (low pressure type)
These transducers measure the suction pressure in each circuit.
They are used to control EXV, evaporating pressure (in heating
mode) and monitor suction pressure safeties related to the
compressor operating envelope. Suction pressure sensors are
located on the common suction piping of each circuit.
■Pump inlet/outlet water pressure transducers
(water pressure type, hydronic kit option)
These transducers measure the hydronic kit pump water inlet/
outlet water pressure and monitor the water ow. Pump inlet/outlet
water pressure sensors are mounted on the optional hydronic kit.
3.6 - Temperature sensors
Temperature sensors constantly measure the temperature of various
components of the unit, ensuring the correct operation of the system.
■Water heat exchanger entering and leaving water
temperature sensors
The water heat exchanger entering and leaving water temperature
sensors are used for capacity control and safety purposes.
■Outdoor air temperature sensor
This sensor measuring the outdoor air temperature is used for
start-up, setpoint temperature reset and frost control.
■Suction gas temperature sensors
These sensors measure the suction gas temperature. They
are used for the EXV control. Suction gas temperature sensors
are located at the suction side of each circuit.
■Master/slave water sensor (optional)
This sensor measures the common water temperature in the
master/slave system capacity control. It is installed only in the
case of master/slave units.
■Defrost temperature sensors (heat pumps)
These sensors are used to determine the end of the defrost
cycle for a given circuit.
3.7 - Actuators
■Electronic expansion valve
The electronic expansion valve (EXV) is used to adjust the
refrigerant ow to changes in the operating conditions of the
machine. The high degree of accuracy with which the piston is
positioned provides precise control of the refrigerant ow and
suction superheat.
■Water ow switch
For units without internal pumps, the water flow switch
conguration allows for the automatic control of the minimum
water ow setpoint of the water ow switch. The conguration
depends on the unit size and is made automatically at the start-
up. If the ow switch fails, the alarm condition shuts o󰀨 the unit.
■Water heat exchanger pumps (optional)
The controller can regulate one or two xed speed or variable
speed water heat exchanger pumps and takes care of the automatic
changeover between these pumps (see also section 6.5).
■Four-way valve (heat pumps only)
The control actuates the four-way valve for cooling / heating
mode and defrosts sessions.

3.9 - RS485 wiring (best practice)
For RS485 ports, one of the following cables can be used:
■two twisted pairs + a shield (RECOMMENDED)
■three wires + a shield
Note that “+” and “-” are communication signals and they are from
the same twisted pair.
The signal ground could be a single wire or a twisted pair and it should
be connected to the “C” pin of J10 (Modbus RTU) or J7 (CCN).
This wire is required so that all nodes on the bus share a common
ground reference connection.
If a shield is used, then the shield cable should be properly
terminated and connected as short as possible at ONLY one
end to the chassis ground (4.3-inch controllers).
3.9.1 - RS485 wiring: 4.3-inch controller
The following diagrams illustrate possible RS485 wiring schemes
for 4.3-inch controllers.
The rst wiring scheme is the best option (RECOMMENDED), but
the second or the third wiring can also be used.
No.1 RS485 wiring diagram (RECOMMENDED)
No. 2 RS485 wiring diagram (CORRECT)
No. 3 RS485 wiring diagram (CORRECT)
No. 4 RS485 wiring diagram (INCORRECT - Do not use!)
No. 5 RS485 wiring diagram (INCORRECT - Do not use!)

C Keep shield continued
D Connect shield to earth ground only at one point
End of Line Resistor: Termination is only needed when running at
bus at very high speed over long distances.
The speed of the bus and the cable distance determine whether
termination is needed. It is meant to balance the bus to minimize
the ringing that may be caused by fast signals and the inductance
of the cabling.
At 9600 baud, termination will have little or no e󰀨ect on the bus.
