The unit is plugged into any open RJ12 socket provided on
the set of diffusers connected to a power pack. One RJ12
socket is available on the back of the diffuser tile on the
MLM connection box and the other RJ12 socket is available
in the trim of the diffuser on the MLM interface board.

Important Rules
ON COMMISSIONING A SET OF DIFFUSERS WITH THE SETUP
MODULE THE FOLLOWING IMPORTANT RULES MUST BE AD
HERED TO:
- Per temperature control zone, one MLM wall-stat is allowed for. Thus if there are fifteen diffusers connected to
a power pack controlling three zones, a maximum of three
wall-stats and/or three analog modules is allowed, one of
each per control zone.
- To set up the control zones, the Setup Module can be
connected to any RJ12 socket on that set of diffusers connected to a power pack – it does not have to be plugged
in at the zone being set up. The Setup Module can be
plugged in while the system is powered up, without resetting the controls.
- To change or select any parameter barring the selection
Operating Instructions
On start-up (power on), the version number will be displayed.
Subsequently the Diagnostic icon is flashed while the unit
collects information from the control system.
Once this information is accumulated, the setup module will
mimic and display the status of the current control zone it
is plugged into. Should no zone be selected at this stage,
the status display is indeterminate and the top left character display will indicate ‘CE’ for control external.
To enter the sub menus, keep the menu button pressed

of control zones, the Setup Module must be plugged into
a diffuser in that particular control zone. It is therefore important to first select the diffusers for a control zone or be
sure it has been selected previously, before changing any
other parameter.
- By factory default each wall-stat and each analog module has the setpoint, room temperature and CO functions
selected. Thus should the installation consist of only a wallstat or an analog module per control zone, the configuration in above is not required.
- The information changes are periodic and some patience
is required while parameters are being exchanged.
- Changing parameters is non-volatile and once selected
and accepted by the system will be permanently stored.
The display will show the current control disk position in
percentage, with the top left character display indicating
‘dr’ for motor drive.
To manually drive the disk, press the up/down arrows
for the required position and press enter.
The double bar icon will flash to indicate the motor is
manually controlled.
