  • Page 5: Icomm™ Compatible Appliances

    Alarm Box - optional system component - see page 21. ICOMM™ SYSTEM LIMITATIONS • The iCOMM™ system does not allow users to adjust or change appliance settings from the iCOMM™ web site. • The BACnet wiring terminal on the CM (Figure 2 on page 6) allows BACnet compliant supervisory controls to monitor and control some appliance settings - see page 31.

  • Page 6: Installation Considerations

    • One available socket at a 120 VAC wall outlet for the iCOMM™ system’s CM for all installations. • If the optional Alarm Box (page 21) is being installed a second 120 VAC socket will be needed.

  • Page 7: Tool Requirements

    • A 120 VAC power strip or 120 VAC outlet multiplier may be required if there are not enough 120 VAC outlets available. This is not included with any iCOMM hardware and is to be provided by customer if needed.

    A process value might be a simple on/off switch or as complicated multi-state value such as control state, but each counts as one of the 75 object per device limit. Every effort has been made to provide the most information possible.

  • Page 35: Hardware Interface

    They are wired together in a “Daisy Chain” fashion from one to another - see Figure 22 on page 33. The iCOMM™ CM BACnet interface supports auto-baud rate detection with a default of 9600baud. Minimum baud rate is 9600 baud and maximum baud rate it is 76,800 baud. It has been tested at 19,200 and 38,400 baud.

  • Page 36: Bacnet Cable Connections

    The network uses shielded twisted pair wire. The BACnet wiring terminal connector on the iCOMM™ system’s CM (communication module) is a 5 pin cage-clamp type plug. One twisted pair is used for the D+ and D- signals and connected to their respective terminals. A third wire (if supplied) is used for the Reference (or common wire) and is connected to the R terminal.

  • Page 37: Bacnet Ms/Tp Network Address

    CONNECTING BACNET BACNET MS/TP NETWORK ADDRESS The iCOMM-CM defaults to a BACnet MS/TP network address of 80. This is the base address with all the connected water heating appliances having MS/TP addresses equal to the base address + its iCOMM™ network addresses. The iCOMM™network addresses can be viewed (see Assign Network Addresses on page 26) with the control system display on each appliance.
  • Page 38 CONNECTING BACNET Changing BACnet MS/TP Network Address (cont) The CM will go through a boot sequence and should display the “Booting iCOMM™ Please Wait” and the “Connecting to Server and Units” messages. If the CM is unable to detect a local network it will display the “No Network Found” error message.
  • Page 39 10 To change the BACnet base address of the CM from the default value of 80 to a new (example) address of 27 type “BA=27” at the iCOMM> command prompt in the telnet window and press the enter key. If entered correctly the command window (see Figure 25) will include the following text: Welcome to iCOMM Communications Module Stand Alone Mode Setup Type: H at the prompt at any time for a list of commands.

  • Page 40: Bms Mode Only

    CONNECTING BACNET BMS MODE ONLY If the iCOMM™ web interface will not be used and the CM will only be connected to a BACnet compliant BMS (building management system) configure the CM for “BMS Mode Only” to disable the “No Network Found” error message using the same telnet session methods described above for changing the CM’s BACnet base address - see Figure 26.
