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 
conguration tool for Carrier communicating devices. The advanced 
SmartView Control comes with web connectivity.
30RBM/RQM units typically use xed 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 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 specic 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 conguration
 ■ 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
