General

The Local Control Panel is supplied with Network Controller(s) and Input/Output Module(s) already addressed. The identification on the panel indicates the Network Controller (NC) ID. Remote Terminals are addressed after the installation.

1. Install all the Remote Terminals as described earlier in this manual.
   
2. Mark the ends of the heat tracing cable circuits as they are connected to the Local Control Panel. For example, heat tracing cable circuit connected to 1C1 and 1C2 is marked "Circuit 1", heat tracing cable circuit connected to 2C1 and 2C2 is marked "Circuit 2", and so on.
   
3. In the event of branched heat tracing cable circuits, identify all Remote Terminals connected to the same circuit with the same circuit number.
   
4. Identify Remote Terminals by Zone numbers, corresponding to the zone numbers in the Local Control Panel, whether they are installed on branched or individual heat tracing cable circuits.

Addressing Procedure

1. Disconnect and lock out all power circuits before working on the Remote Terminals.
   
2. Note the Network Controller (NC) ID identified on the Local Control Panel.
   
3. Remove the Remote Terminal cover to expose the printed circuit board and the addressing dip switches.
   
4. Set the NC ID dip switch as indicated noted from the Local Control Panel.
   
5. Set the Remote Terminal dip switch as per Zone markings made earlier (see Table 2).
   
6. Set the Voltage Selector Switch to proper voltage (115V or 230V).For 208, 230 and 277V systems use 230V setting.
   
7. Close the cover and tighten the screws on the Remote Terminal.
   
8. Mark the weatherproof label (provided on the Remote Terminal cover) as per settings made with permanent marker.

Dip Switch Addressing

Table 2. Remote Terminal (RT) ID.

Adding Zones Disconnect and lock out all power circuits before working on the Local Control Panel components. Install and properly address additional Remote Terminal(s) as per instructions, and Tables 1 and 2. NC-2104 Network Controllers and IO-2104 Input / Output Modules contain dip switches for setting up the number of zones (Remote Terminal addresses) that will be monitored. When the Local Control Panel is ordered with spare zone(s) capability, the necessary Network Controller(s), Input Output Module(s) and associated switching contactors are furnished pre-wired to handle these spare zones.The Network Controller(s) and Input Output Module(s) are preset at the factory to handle the actual number of zones (Remote Terminals) that are furnished with the specific order. Monitored zones are marked on a Network Controller as Z1 through Z4; and on Input Output Modules as Z5 through Z8, Z9 through Z12, etc.  Determine the appropriate Network Controller or Input Output Module, which will indicate and control additional zone(s). Disconnect all wiring connections by unplugging the Network Controller or Input Output Module terminals, and remove the faceplate and the printed circuit board. Remove the appropriate Network Controller's or Input Output Module's faceplate and the printed circuit board by removing four corner screws. The "No of Zones" dip switch has 4 positions. Each position represents an active zone. Place appropriate dip switch position(s) into ON state to activate additional zone(s). Place the faceplate and the circuit board back. Fasten the four corner screws. Reconnect all wiring connections by plugging the Network Controller or Input Output Module terminals back into original places.
