Modbus Control
If the humidifier is to be controlled using the standard Modbus interface then the Source
parameter in the Control Setting Menu must be set to Modbus (see page 56). When Source =
Modbus the humidifier will operate on the basis of digital inputs from the Modbus network and
ignore any analog inputs. See Modbus Digital Control on page 35 for other requirements for
Modbus control and/or monitoring.
BACnet MS/TP and IP
If the humidifier is to be controlled using the standard BACnet IP interface, then the Source
parameter in the Control Setting Menu must be set to BACnet (See page 60). See supplemental
Building Management manual for more information.
Other Building Automation Systems
Additional protocols such as LonWorks and Johnson N2 can be used with the NH-EL by
purchasing the respective Building Automation System option. See supplemental Building
Management manual for more information.
Nortec ONLINE
Nortec OnLine enables a humidifier to communicate and be monitored through the Internet.
Nortec OnLine is built into the NH-EL. See Nortec Online on page 60 for configuring the NH-EL
to operate on Nortec Online. See supplemental Building Management manual for more
