• Is established at the request of a service technician by pressing the Central
Hub center pushbutton
• Is managed by the Central Hub
• Operates while the Central Hub is connected to the business network – or not
• Operates whether the business network is running or not or is connected to
the Internet or not
• Allows only a special Lennox-managed Central Hub ↔ nearby local network
to run over it (Brown)
• Is separate from, and not connected to the business network
The Central Hub internal Wi-Fi module can remain connected to the business
network (and the Lennox iCON cloud servers and other Central Hubs in the
business) while establishing and maintaining a special ad hoc peer-to-peer
(P2P) Wi Fi physical network between itself and a nearby device running the
Lennox iCON Remote Facilities Portal.

Central Hub ↔ Lennox iCON Cloud Server Network
The Central Hub ↔ Lennox iCON cloud server network is marked as red in
"Figure 1. iCON Hardware Architecture" on page 7:
• Is a private Lennox-managed network between one Central Hub in a business
and iCON cloud services
• Is a secure network
• Runs on the business network, through the business router, through the
Internet, to a Lennox iCON cloud server
Through this private Lennox-managed network:
• iCON web-portal can access and control the iCON system installed in the
business from remote locations
• iCON system and HVAC equipment registration and user account creation is
accomplished
• Lennox iCON cloud services discover and register additional or replacement
HVAC equipment installed in the business
• iCON system and HVAC equipment installation and performance data is
collected.

Central Hub Connection to Lennox iCON Cloud
Services
When a Central Hub first connects to a functioning business network that is
connected to the Internet through a router in the business, it sends a request
to Lennox iCON cloud services. This request is for a special private Lennox-
managed network to be established over a secure (https) connection between
that Central Hub and a Lennox iCON cloud server.
Once established, no other device can join that particular network.
The Lennox iCON server learns the identity of the requesting Central Hub and
adds that information to the Lennox iCON cloud services database of Central
Hubs.
If the connection between the Central Hub and the Lennox iCON cloud server
is interrupted for any reason (business power failure, Internet outage, etc.), the
server will recognize the Central Hub when the connection is restored and the
Central Hub requests a connection. Communication and activities between that
Central Hub and the Lennox iCON cloud pick up where they left off.

iCON and HVAC Equipment Registration and User
Account Creation
During the installation and setup process, the iCON system and the HVAC
equipment connected to it is registered with Lennox iCON cloud services
(system registration). System performance, event, and alarm data collection
begins.
The iCON and HVAC equipment registered will always be associated with the
business and its location until they are replaced or removed from service.
When an HVAC component is replaced or a new one is added, the Lennox
iCON server will discover the change and add the new equipment to the system
registration.
Once the system is registered, the business owner can create a user account
on the Lennox iCON cloud server. This is a separate process that allows there
to be a user account that can be associated with one or multiple iCON systems
installed in one business, or with multiple iCON systems installed in multiple
businesses.
For example, a single site may have several iCON control systems installed in
it. A user account can be associated with each of the iCON systems installed
at all the sites.
If a business owner sells a business containing one or more iCON systems
associated with his or her user account, the system registration for the iCON
system(s) and attached HVAC equipment installed in that business remains
unchanged. Then, when the new owner creates a user account, the previous
owner's user account is disassociated from the equipment installed in the
business that was sold.
7.8.
Remote Control of the iCON System
Once an iCON system is registered and a user account is set up, the iCON
system can be controlled remotely from a computer using a web browser.
These services operate only through user and installer accounts on the Lennox
iCON cloud servers and are rigorously authenticated.
• For the business owner, the web portal application provides the full
functionality of the Local Display installed in the business and allows the user
to monitor and control the iCON and HVAC equipment.
