2.1 - Control system
61AF units come with the SmartVu
TM
control that serves as a user
interface and a conguration tool for controlling the operation of
the heat pump.
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 unit to
maintain the correct refrigerant pressure in the circuit and monitors
safety devices that protect the unit against failure and guarantee
its optimal functioning.
SmartVu
TM
control system:
■ Manages compressor to control the water loop.
■ Controls xed or variable-speed pumps to optimise water loop
operation.
■ Allows users to control the unit via the SmartVu
TM
user interface.
■ Provides web connectivity technology.
■ Supports Carrier Connected Services (Remote connectivity,
alarm notication, remote access, performance and operation
automatic reporting, technical advice).
■ Provides direct BMS integration capabilities (RS485 / Ethernet).
2.3 - SmartVu
TM
components
The controller manages a number of mechanisms that allow the
unit to operate e󰀨ectively, including the following:
■ 4.3’’ touch screen
■ BMS connection
■ Scroll compressor technology
■ Diagnostics
■ Web connectivity / e-mail transmission
■ Heating control
■ Electric Heating Stages control
■ Domestic Hot Water production (optional)
■ Boiler control (optional)
2.4 - 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.
