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 al-
lowed 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 con-
nected 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 reset-
ting the controls.
- To change or select any parameter barring the selection
of control zones, the Setup Module must be plugged into
a diffuser in that particular control zone. It is therefore im-
portant 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 mod-
ule has the setpoint, room temperature and CO functions
selected. Thus should the installation consist of only a wall-
stat or an analog module per control zone, the configura-
tion 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.
On start-up (power on), the version number will be dis-
played.
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 charac-
ter display will indicate ‘CE’ for control external.
To enter the sub menus, keep the menu button pressed
until the unit beeps.
SUB M SUPPLY AIR TEMPERATURE
The top left character display will indicate ‘CO’ for change-
over or supply air temperature value. A value of zero indi-
cates the CO sensor is not selected or not connected.
To advance to the next menu, press the menu select but-
ton.
SUB M CONTROL DISK POSITION
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.
Verify the disk movement of all diffusers in that control
zone and the position display update.
To advance to the next menu, press the menu button.
The control will revert back to automatic.
SUB M CONTROL DISK O OP
The display will show the open end-stop disk position in
percentage, with the top left character display indicating
‘dr’. The down arrow and single bar will flash to indicate
‘open end-stop’
