Single Appliance Networks
(page 12)
with one “tank type” water heater connected
:
The network address for the tank type water heater is automatically set to “1.” The installation
technician does not need to make any changes in the appliance control system menus. There
will not be an active menu item for viewing or changing the network address in the water heater’s
control system.
2 On
Multiple Appliance Networks
(page 16):
Allow 1 - 2 minutes after powering up the CM for appliances to complete network connections.
Using the appliance’s UIM (user interface module) navigate to the network address setting for
each appliance - see Figure 20.
Ensure every water heating appliance connected to the CM (communication module - page 6)
has a
“unique”
network address between 1 and 31,
this is a critical requirement.
Network addresses do not have to be sequential (1, 2, 3 etc) but each appliance must have a
unique number. IE: four water heating appliances could have the following network addresses; 1,
3, 6, 31.
See the control system menu illustrations in Figure 20 below for tank type water heaters.
See the appliance Instruction Manual(s) or control system help menu on how to change settings.
Instruction Manuals can be obtained at the manufacturer’s web site or by calling the technical
support phone number listed on the appliance labeling and the back cover of this manual.
3 Ensure no appliance has a network address of “0.” A network address of 0 will prevent the
appliance from being recognized by the CM (communication module) on the network.
4 Power cycle all appliances (turn off power for 10 seconds then restore power) on the network.
5 Reboot the CM - disconnect the round “5 VDC” power plug to the CM for 10 seconds. Reconnect
the round “5 VDC” power plug to the CM and wait 5 minutes to establish all connections.
