INTRODUCTION
This manual provides installation, operational and set up instructions for the iCOMM™
remote monitoring system hardware. In this manual the terms “Appliance,” “Unit” and
“Device” are synonymous with tank type water heaters.
SYSTEM OPERATION & FEATURES
Remote Monitoring - Internet
The iCOMM™ system allows users to remotely monitor operational and diagnostic
information of iCOMM™ compatible water heating appliances. Appliances are connected to
the iCOMM™ system’s CM (communication module - page 6) and the CM is connected to
the Internet. Users log on to a secure web site maintained by the appliance manufacturer to
monitor appliances.
Operational and diagnostic information accessible through the appliance’s control system
locally can be viewed remotely from any location that has Internet access.
BACnet Compatibility
In addition to web based monitoring iCOMM™compatible water heating appliances will be
able to communicate with BACnet compliant supervisory controls and building management
systems through the iCOMM™ system’s CM - see page 31.
Automated Service Notifications
The iCOMM™ system can automatically notify selected employees and service personnel
via email and/or cellular phone text messages whenever operational problems or user
defined Alert Conditions occur. Operational problems and conditions that can initiate an
Automated Service Notification include:
• Fault/error/lock out conditions declared by any connected water heating appliance.
• Water leaks detected by the iCOMM™ system Leak Detector component (page 10).
• Low Water Temperature Alarm (settings for this feature are made on iCOMM™ web site).
• Various user defined Alert Conditions such as maximum cycle count, run time, elapsed
time, heating time and communication failures (settings for this feature are made on
iCOMM™ web site).
Historical Data Graphs
Graphs showing operational data such as system temperature and run time for a water
heating appliance during user defined time periods are calculated and displayed online.
Estimated Operating Costs
Estimated utility costs savings (compared to standard 80% thermally efficient products) are
calculated and displayed on the iCOMM™ web site for each connected appliance.
Appliance Run Time
Appliance run time (wear) data is collected and displayed online. This data can be used to
implement planned replacement policies and to forecast and budget for replacement costs.
This can help minimize lost income due to unexpected equipment failure.

knockout hole - see Figure 9 on page 15.
6 On CSB IFE models that do not have a factory provided 1/2” knockout use a portable drill and a
1/2” electrical knockout punch/die (see Tool Requirements on page 4) to add a knockout hole on
the top plate of the control cabinet. Locate the knockout hole as shown in Figure 9 on page 15.
Take steps to ensure metal shavings do not fall into any electrical components such as the CCB,
contactors or fuse blocks when cutting the knockout hole. After the knockout hole has been
added to the top plate of the control cabinet install a Knockout Bushing (Table 1 on page 7) in the
knockout hole.
7On Single Appliance Networks: route the network cable from the CM (see page 11) through the
knockout bushing and plug the cable into the J9 socket on the CCB - see Figure 8 and Figure 9
on page 15. Proceed to the Start Up section on page 25 when these connections are complete.
8On Multiple Appliance Networks: all tank type water heaters on the network require a MDA
(multiple device adapter) - proceed to page 16.
If any gas fired tank type water heaters are to be added to the network see page 12.

CONNECTING TANK TYPE WATER HEATERS
MULTIPLE APPLIANCE NETWORKS
Multiple Appliance Networks are formed by connecting network cables between multiple
tank type water heaters and the iCOMM™ system’s CM (communication module) in a “daisy
chain” configuration - see Figure 15 on page 20.
Multiple Device Adapters - MDAs
“Tank type” water heaters in a Multiple Appliance Network require MDAs (multiple device
adapters) to be installed on each water heater in the network - see pages 19 and 20. MDAs
have two female RJ45 sockets and a short length of network cable with a male RJ45 plug.
There is a small green LED light on the top that verifies power from the CM is present at the
MDA - see Figure 10.
MDAs are sold separately as a kit. One MDA kit must be ordered for each tank type water
heater connected to a Multiple Device Network. Each MDA kit comes with the items listed in
Table 3. Ensure all these parts are present before you begin the installation.

Multiple Appliance Network Guidelines
1 If more than one water heating appliance will be connected to the network the “MULTI PORT”
socket on the CM (communication module) must be used to connect the first appliance. See
Figure 11 and Figure 15 on page 20.
2 The “SINGLE PORT” is only used when one “tank type” water heater is connected to the CM.
3 The “LAN PORT” is used to connect the CM to the local Internet service - see Figure 11.
4 Each tank type water heater on a Multiple Appliance Network must have a MDA (multiple device
adapter) installed. See Figure 10 on page 16, Figure 13 and Figure 14 on page 19. MDAs are
ordered separately. One MDA kit should be ordered for every tank type water heater being
connected to a Multiple Appliance Network.
5 Multiple Appliance Networks can have a maximum of 7 tank type water heaters connected to a
single CM - see Figure 15 on page 20. If more than 7 tank type water heaters are present
additional CMs must be installed.
