2 - CONTROL OVERVIEW

2.1 - Control system

30RBM/RBP chillers and 30RQM/RQP heat pumps are equipped
with SmartView Control that serves as the user interface and
configuration tool for Carrier communicating devices. The advanced
SmartView Control comes with web connectivity.
30RBM/RQM units typically use fixed speed fans and 30RBP/RQP
units use variable speed fans. Variable speed fans reduce the unit
energy use during occupied and unoccupied periods, provide
condensing or evaporating pressure control and smooth fan start.
For both 30RBM/RBP chillers and 30RQM/RQP heat pumps, the
system may control fixed 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 specific 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.

SmartView control system:
■ Allows users to control the unit via the SmartView user interface
■ Provides web connectivity technology
■ Includes the trending functionality
■ 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 configuration
■ Provides direct BMS integration capabilities (CCN RS485,
ModBus RS485 option, LON option, BACnet IP option)

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 or BACnet). 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 offer any of the
features of the Network.
CAUTION: Emergency stop! The Network emergency stop
command stops the unit regardless of its active operating type
