Nortec NH Series - Manual (Page 35)

Installation | 32
Keep Warm (Outdoor Standard)
Menu configuration setup can be done at factory, which allows the water temperature in the
tank to be maintained at 160ºF (70ºC) for quick response of the unit to a call for humidity. This
aids in minimizing health concerns associated with standing water.
Part number 1504561.
Nortec Online/LINKS2
Nortec OnLine enables a humidifier to communicate and be monitored through the Internet.
Several configurations are available: Dynamic Host Configuration Protocol (DHCP), Dial-up,
General Packet Radio Service (GPRS), Slave, and Static IP. Consult factory for details.
Nortec LINKS provides monitoring and control allowing humidifier(s) to communicate to a
Building Management System (BMS). The controller is factory installed and is located internally
to the humidifier. Several communication protocols are available: BACnet MSTP, BACnet IP,
Johnson N2, and LonWorks. Consult factory for details.
Nortec LINKS2 is a package that includes both items above: a particular communication
protocol as well as Nortec OnLine.
Remote Relay Board
An optional remote fault kit is available that can provide remote indication of humidifier status.
The relays will activate upon the following humidifier conditions: steam production, unit fault,
maintenance/service, and unit power. The kit can be factory or field installed and can interface
with a BMS. See Page 30 for wiring and installation.
Part number 1508069.
Scale Management System
The Scale Management System provides a separate reservoir underneath the steam tank for
scale collection. The addition of this option reduces maintenance time significantly. Minerals
removed from the water during steam production will collect in the scale reservoir rather than in
the tank. When minor maintenance is needed, the scale reservoir is easily removed and
emptied. Without this option, the NHRS requires more effort during minor maintenance:
cleaning of the steam tank and heating elements. More humidifier downtime is required for this
maintenance. With the Scale Management System, minor maintenance simply requires the
scale reservoir to be emptied, which can be done in a matter of minutes.
Part number 2533179 (two must be ordered for units with two tanks, NHRS 135 & NHRS 180).
Solid State Relays
Solid State Relay Control (SSR Control) allow for rapid response upon a call for humidity by
replacing the standard contactors with a higher-performing component. The operating window
for the standard contactor is 2 minutes, but the SSRs will cycles in approximately 2 seconds.
This allow for quick response and tight control of the humidity. This option is essential where a
tight humidity tolerance is required.
Part number will vary according to the capacity and voltage of the unit.
