5. iCON System Hardware
5.1. Central Hub
•
Typically mounts in the business office space;
• Contains the main processor and controls the iCON thermostat components
and the HVAC components that are connected to it
•
Communicates with the installed HVAC equipment over regular four-wire
thermostat cable
•
Connects to Lennox iCON cloud servers through the business network to
receive firmware updates, and to provide system status information and
system control capabilities to business owners remotely
5.2. Mag-Mount
•
Attaches to the wall and provides a physical attachment for the Local Display;
•
Receives power from the Central Hub and communicates with it over regular
four-wire thermostat cable
• Acts as a communication bridge between the Central Hub and the Local
Display
5.3. Local Display (HD Display)
• Is an LCD touch screen that snaps onto the Mag-Mount
•
Receives power from the Mag-Mount and communicates with it through
electrical contacts on the back of the case
• Shows system information such as room temperature, room humidity, set
points, local weather, and system status
•
Provides a touch screen graphic interface for the user to turn features on
and off, change set points, set up and select schedules, and adjust system
parameters
•
Contains the primary room temperature sensor as well as various other
sensors such as user proximity
5.4. iCON Building Controller (16A50)
• This controller is used to connect all the lighting, automation, and other
devices in the building
•
Configured via local display
• Building Controller address is assigned during installation
•
Installer defines rules on the building controller to trigger Alerts
• Refer to the ICON Building Controller Installation and Setup guide which is
included with the controller for further details
6. iCON Hardware System Architecture
6.1. Equipment Monitoring
The system can monitor up to the following:
• 93 rooftop units (M1-8, M2, M3 and NTC)
• Four iCON Building Controllers (building automation)
•
Sixteen Energy Monitoring MTUs
6.2. Equipment Interfaces Supported
• S-Bus (HVAC)
• M-Bus (Building Automation)
• TCP/IP (Energy Monitoring)
7. Central Hub Descriptions
The iCON Central Hub is the focal point for the business HVAC system. It is
typically mounted near the mechanical room of the business and is wired to
the rooftop units (RTU) using common four-conductor 18 AWG wire. The field
supplied transformer supplies 24VAC power to the Central Hub.
7.1. Central Hub
The Central Hub contains these main functional blocks:
• Microprocessor that manages the Central Hub, Mag-Mount / Local Display,
and the connected HVAC system
• A wired serial communication interface to the iCON Mag-Mount / Local
Display
• A wired serial communication interface to the HVAC roof top unit(s)
• A USB host
• A Wi-Fi radio module for wireless communication with the business Wi-Fi
network and local Lennox devices
• A pushbutton switch for system reset and initiating communication with local
Lennox devices
• LED indicators to show system status
• Power supplies for itself and the iCON Mag-Mount / Local Display
The Central Hub provides the following main functions:
•
Receives user control inputs from the Local Display
•
Receives status information from other HVAC components in the system
• Sends HVAC system status and other information to the Local Display for
viewing by the user
