CONNECTING TANK TYPE WATER HEATERS

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.
