Variable Definition
In the variable name, “_x” denotes the humidifier number. If there is only one humidifier, all
variable names will end in “_1”. If two units are networked together, see Figure 4, the second
unit’s variable names will end in “_2”. For 3 networked units, “_3” and so on. If unsure of the unit
number, each unit will have a label, in the electrical compartment close to the terminal strip,
indicating the device instance of each humidifier.
Nortec Links2 is capable of communicating a variety of variables for each unit that is connected to
it. For a variable listing and definition refer to Table 4. Network variable addresses for the
humidifiers may be seen in Table 5 to Table 12.
