Multi-Unit Systems (“Master/Slave”)
Up to 8 humidifiers can be chained and monitored through a single Links2 package. In this
configuration, the unit with the Links2 package is designated the “Master Unit”, while the
remaining 7 humidifiers are configured as “Slaves”. The master unit is connected to the Building
Management Systems (BMS). Each unit is separately addressed, it is possible to monitor and
control each unit individually.
Different networking configurations may be achieved depending on the type of network being
used. One networking example could have a Gateway installed inside the lead unit, which could
then be daisy-chained to successive units. In turn, the lead unit would connect to a Building
Management System (BMS) network via a shielded, twisted-pair connection. Please see wiring
section for additional detail. A second example could have a series of units directly connected to
an Ethernet network. This is only possible for BACnet communication and is essentially referred to
as a BACnet/IP configuration.
