3. Select from "0-5V", "1-5V", "0-10V", "2-10V", "0-20V", "0-16V", "3.2-16V", "0-20mA", or "4-20mA",
as appropriate for the external control device connected to Channel 1.
This concludes the basic setup of the control software.

Configuring for Multi-Unit Operation
Set up the control software for multi-unit operation as described below. A maximum of four humidifiers
can be set up in a "Main-Extension" configuration using Condair's Linkup system to satisfy large hu
-
midification needs.
IMPORTANT!
This procedure should only be used to control multiple humidifiers that are using the
same control signal inputs from the same conditioned environment.
1. Make sure that all wiring and jumpers are installed, as described in "Connecting Multiple Units Using
Linkup" in the Installation Manual.
2. Configure the main humidifier as described in
"Configuring the Control Software" on page 39
3.
Set
to "Main" on the humidifier that will be designated as Main in the Linkup chain, and set
up the following parameters on it:
– select the total number of humidifiers in the Linkup chain. For example, if there is
one main unit and two extension units, then the total number of humidifier in the chain is 3.
– select the mode of operation of the humidifiers in the Linkup chain ("Series" or
"Parallel").
– enable or disable the function that manages the starting order to balance the
operating hours on each steam cylinder. Note: This setting is available only if
to "Series".
– set the time interval used by the control software to establish a new operating
sequence to balance the operating hours on the steam cylinders in the Linkup chain.
– if required, change the maximum time limit that the units in the Linkup chain can
operate without a connection to each other before they generate a Linkup Timeout warning
message.
– if required, set the percentage value of the system demand signal at which the unit is
switched on.
– if required, set the percentage value of the system demand signal at which the unit
achieves 100% demand.

in each extension humidifier as Ext1, Ext2, ...
Note
: Each extension unit must be a unique extension number.
The humidifiers in the Linkup chain are now set up to generate steam upon humidity demand.
