COMMUNICATION INTERFACES AND
SUPERVISION:
The CLIMATIC ModBus interface is required to connect the unit
to a BMS using "ModBus protocol". No other hardware than this
board is required to have ModBus communication. One board
required per rooftop. The ModBus interface is available in two
versions to be connected with RS485 or TCP/IP depending on
site requirements.
This board is also mandatory for any connection between one
or several
FLEXAIR units and Lennox ADALINK II, Lennox
OneWeb, Lennox Cloud service 3G or LennoxVision supervision
solutions. One BMS interface required per rooftop.
ADALINK II™
Adalink II™ is Lennox’s simplest solution for HVAC installation
supervision to better control the system and improve reliability
and energy ef
fi ciency. One ADALINK II™ can control up to 32
Lennox units on the same site (Chillers, rooftop or any other
unit using controller and above). It displays a site picture with
the status of each unit and allows the user to change set points,
access alarm history and plot charts. It is the ideal tool to save
time and money on maintenance with an expert mode giving
access to all the parameters and set point of the unit.
• Easy local management of important settings
• Possibility to create macro commands to simplify setting and
better control the installation
• Easy scheduling by unit or by zone with a smart user friendly
drag and drop system
• Preventive maintenance to reduce downtime and improve
comfort and energy ef fi ciency at all time.
• Remote connection via LAN or 3G
• Site maintenance planning
ADALINK II™ can also act as a real gateway to the unit, as it can
be used locally or via LAN network with ModBus TCP/IP protocol.
Any BMS can read and write information in the rooftops units using
ADALINK II™ network. Both systems can run at the same time.
