Configuring The Humidifiers
1. Since Nortec Links2 can connect to a maximum of 8 units, it will be necessary to set the unit
address for each humidifier. The lead unit can be determined by the presence of the Links
module. The slave humidifiers can be given a unit address according to the number the unit
will have on the networked chain.
2. To access the menu settings, press the Up and Down arrows at the same time
3. Scroll up or down to find the Modbus heading
4. Set the appropriate Modbus address according to the unit ordering.
5. Place the appropriate Unit Identifier label on each humidifier. These labels should be placed
on the unit where the electrical control punch-outs are located at the top of the humidifier.
6. Connect the slave humidifiers (if applicable) to the Nortec Links Module. A twisted pair cable

(+) terminal on the slave unit. The Net (–) terminal on the module should be connected to the
Net (–) terminal on the slave unit. Refer to the Links2 wiring diagram for more information.
