System Overview
The Multipoint Control Box 8 zone system comprises of one of each of the following
components:
• Multipoint Control Box 8 zone module
• 24 VAC Transformer
In addition to the control box module and transformer you will require at least one wall
switch module and multiple zone dampers for multizone on/off control:
• Multipoint 2, 3 or 4 zone wall switch (MPWS234).
• Multipoint 5 or 6 zone wall switch (MPWS56).
• Multipoint 7 or 8 zone wall switch (MPWS78).
• My Zone Touchpad (MZTP8). Refer to this manual for Fujitsu Bridge installation.

Multipoint Control Box 8 Zone Module
The Multipoint Control Box 8 zone module is the core component of the Multipoint
Zoning System. All zone motors and wall switches connect to and receive power from
the control box module. All wall switch and motor connections are made using the plug
in cable system for easy installation, terminal connections are provided for the 24V
power supply.
Up to 2 wall switch modules may be connected to the control box module as standard.
To connect more than 2 wall switches an expansion module is required.
The control box module is physically designed to offer simple installation and operation
and may be either Din rail or surface mounted.

Multipoint Wall Switches
Multipointwallswitchesareavailablein2,3,4,5,6,7and8zonecongurations,and
connect to the control box module via a synchronous data bus.
Each wall switch has one socket which connects directly to the control box module.
The 2, 3 or 4 button wall switches (MPWS234) are set to the required number of zones
by positioning a jumper on the back of the wall switch during installation.
The 5 and 6 button (MPWS56), and 7 and 8 button (MPWS78) wall switches are also
set to the required number of zones using a jumper during installation.
The top button (determined by the overlay used - not the switches on the hardware)
corresponds to the motor output 1 on the control box module.
A 2 button wall switch will control motor outputs 1 and 2 only. A 5 button wall switch will
control motor outputs 1, 2, 3 4 and 5 only. The 8 button wall switch controls all 8 zones.
Motorised Dampers
Motorised dampers connect directly to the control box module via the motor output
sockets.
Component Positioning
The control box module and wall switch expansion modules can be positioned on or
near the systems air handling unit, or in the mechanical services switchboard.
The wall switch should be mounted in a central location within the air conditioned space.
Theyaredesignedtobeushmountedtoacavitywall,butmaybesurfacemounted
through the use of a mounting block not less than 15mm deep.
The motorised dampers can be mounted at the takeoff point of the rigid duct or mounted
in-lineintheexibleduct.
Commissioning
Prior to applying power to the system, double check all wiring connections. Ensure
motors are connected to motor outputs and touchpads to touchpad outputs.
Set the spill zone(s) if required. To set the spill zone(s), move the respective switch in
the spill zone DIP switch block on the control box to the ‘on’ position. Any number or
combination of zones may be set as spill zones to suit the installation. Refer to the A/C
unitspecicationstodeterminetheminimumairowthatisrequired.
Thespillzone,whenset,ensuresairowacrossthecoilismaintainedatacceptable
levels. If the user turns all zones off, the designated spill zones are forced to open.
Turnallzoneson,thenturnontheindoorfantoensureairisowingtoeachzone.
Turn each zone off in turn to ensure the zone dampers are functioning correctly and the
zones match the names on the wall switch. Turn all zones off to ensure the spill zone is
functioning (if set).

Wall Switch Zone Number Selection:
The jumper blocks on the back of the wall switches are used to set the number of zones
controlled by the switch.
The top button (determined by the overlay used - not the switches on the hardware) on
each wall switch corresponds to zone 1 output on the control box module.
Example
For a 5 button wall switch the top 2 buttons and the bottom button of the wall switch
hardware are disabled by placing the jumper across the pins at JP4 on the back of the
wall switch. See image next page.
Once the number of zones for the wall switch has been selected place the zone labels
in the appropriate position on the front of the switch prior to sticking the overlay in place.

Wall Switch Operating Instructions:
To operate a zone, simply press the button to turn the respective zone on or off.
The green LED beside the button is illuminated to indicate the zone is on.
Fullairowshouldbeavailablefromtensecondstotwominutesafterswitchingthezone
on, depending on the stroke time of damper motor being used.
In the event of a power loss and restore to the controller (ie. blackout), the controller will
resume operation with all zones in the on / off state last set by the user.

Crimping Instructions
Never insert uncrimped plugs into
the sockets.
Doing so may cause damage to
the socket contacts. Crimped plugs
should insert easily into sockets
until the locking tab clicks into place.
Plugs that have been incorrectly
crimpedmaybedifculttoinsert,
and may cause damage to the
socket contacts if forced into place.
Step 1
• Cut the cable to the desired length.
Take care to ensure the ends are cut
square.
Step 2
• Insert the cable between the stripper
blades of the crimping tool so that it
touches the metal stop.
• Squeeze the handles and pull the tool
to remove the cables outer sheath
and expose the insulated inner
conductors.
• Ensure the insulation on the inner
conductors is not damaged.
Cable connections are polarity
conscious.
It is essential that every cable
termination for each installation is
performed with the coloured inner
conductors in the same order and
position in the plug. Any two cable
ends should appear identical if held
side by side (provided they are of
the same cable type - i.e. shielded or
unshielded).
Step 3
• Insert a plug into the plug holder
of the crimping tool. It will click into
place.
• Insert the prepared cable end into
the plug, taking care to ensure the
coloured inner conductors are in the
same order and position each time.
• Squeezethehandlesrmlytosetthe
contacts and secure the cable.
