MLM INTEGRATION WITH BMS
The Light Switch icon in the MLM Tools shows the current selection as well as the status of the Light Switch
node.
A channel block coloured in green will indicate the switch is activated (closed).
The adjacent picture shows the occupied Delay period 1 has timed out, which caused the Switch A channel to
disconnect. The Switch B channel is still connected.
Airflow sense setup and operation
This section describes how to set up the flow sense operation in the MLM Tool for a single diffuser and then the
zone for that diffuser. Once the basic flow operation is understood, the user is advised to follow the procedure
in the MLM Help file, Main Menu/Wizards. It deals extensively on how to set the flow min/max control on a
MCU (segment) scale, including import and export functions.
A few basic checks to ensure the correct operation:
Ensure the correct firmware revisions are loaded for the Diffuser controller, On-Board Master and Wallstat
nodes. Check the release notes on the Trac download site http://trac.lhar.co.za/ .
Ensure that firmware revision 6.08 or higher is loaded onto the MCU 2 unit.
Ensure the MCU Flow coefficient file is up to date (File/Update MCU Flow Coefficients).
Ensure MLM Tool rev 8.14 u3 or higher.
Verify that the diffuser Type and Neck Size is correctly set on the Diffuser controller node (see picture).
Ensure a flow sensor is correctly fitted to the diffuser neck.
