on page 26 .
Basic Tab
– Source: allows you to select the source of incoming con -
trol/humidity signal to the humidifier.
Options:

are from analog sensors or humidis -
tats connected to the humidifier's low
voltage terminal block.
Modbus

from the BMS via the Modbus com -
munication protocol.

from the BMS via the BACnet/IP
communication protocol.

Analog
– Dual Cylinder Mode: allows you to configure the opera -
tion of humidifiers with dual steam cylinders. Note: This
function appears only on units with dual steam cylinders.
Options:
Parallel
– the cylinders operate in
parallel based on humidifier demand.
This results in a lower turn-down
ratio, but even wear on both steam
cylinders.
Series – the cylinders are modu -
lated in sequence to meet humidifier
demand. Cylinder A will operate from
0-50% demand, and Cylinder B will
operate from 51-100% demand.
Independent – the steam cylinders
work independently based on control
signals from two separate zones.
