01 Introduction
The MyZone 2 system had been developed to provide
individualised control over airow in each room.
Traditional zone selection systems provide two
position on or off control over airow often resulting
in over or under conditioning. The MyZone 2 system
allows the occupant of each room to adjust the
airow to precisely match their comfort target.
MyZone 2 comes standard with two touchpad ports.
MyZone 2 can operate with two types of
motorised dampers. The ZoneBoss Modulating
motor (default) or the Belimo LMU Series.
Damper selection is done through the Settings
menu. Other conguration features include
total zones present, favourites present, spill
display/hide, buzzer enable/disable.
MyZone 2 provides an unparalleled level of control
over the airow in every zone guaranteeing
that comfort expectations are met.
02 System Overview
MyZone 2 is ideally suited for any structure
with dynamic heat loads, especially residential
applications where individual requirement
differs for each room. The system is implemented
independently of the plant controller.
2.1 How it Works
Although the installation, commissioning
and operation of the system are simple the
actual control process is ingenious. The
operation can be separated into 3 areas:
 Individual Zone Airow Management
 Total Airow Management
 Safety Modes
2.1.1 Individual Zone Airow Management
One of the strengths of the MyZone 2 system is the
way it handles each zone as an independent entity.
The zone damper position can be adjusted for each
zone in ve percent increments providing precise
ow control in each room. A time proportional
damper positioning algorithm (TPDP) is used
to modulate and monitor damper position.
2.1.2 Total Airow Management
As damper positions change in individual zones
MyZone 2 recalculates the total airow requirement
and uses a spill function to maintain system
operating pressures within acceptable range.
2.2 System Components
The MyZone 2 system is tailored to suit each
application by incorporating the following
components into a standard ducted HVAC system.
 MZWFCBT8-V2 (Control Box & Transformer)
 MZWFTP8-V2 (MyZone 2 Touch Screen)
2.2.1 MZWFCB8-V2
The MyZone 2 Control Box includes eight damper
outputs, 2 touchpad ports and spill selection.
2.2.2 MZWFTP8-V2
The MyZone 2 Touch Screen provides an interface
for precise damper positioning and user control.

Zoning systems seem complex, however the MyZone 2
system has been designed to dramatically simplify
the cabling process. The key to its simplicity is in the
way the different processes have been separated.
a. Zone motors connect to the 6P6C
RJ12 damper output sockets.
b. MyZone 2 Touch Screen connects
to the touchpad socket.
4.1 Wiring
Shielded cable to all touchpads and sensors is
recommended to minimise the effects of external
interference. Cabling regulations apply.
Cables are to be kept to the maximum
practical distance from any power cables
≥240volts (minimum distance 300mm).
Maximum cable length is not to exceed 20m.
28AWG or higher 6P6C RJ12 cable must be used.

3.5 Zone Motor Ratings
The MyZone 2 system is specically designed
for operation with 24 volt motors. All dampers
in a MyZone 2 system must have the same
actuator type. Please refer to the relevant
Actuator Data Sheet for more details. MyZone 2
works with three position actuators only.

4.2 Component Positioning
The following are recommended positions for each
of the required components for a MyZone 2 System.
4.2.1 Control Box (MZWFCBT8-V2)
The main processor module is best installed within
the ceiling space either mounted on the fan coil unit
or on the supply air duct. The mounting point should
be relatively clean, dry and free of excess vibration.
Maintain a minimum distance of 300mm from
sources of electromagnetic interference
(EMI) such as fan motors etc.
4.2.2 MyZone Touch (MZWFTP8-V2)
The MyZone 2 touch screen is best installed off the
 oor, in a central location within the occupied area of
the premises. In cases where more than one touchpad
is used it may be appropriate to position touchpads
in zones to facilitate remote control. One touchpad
on each  oor or in each zone is often the case.
The touchpad has been designed to be mounted
using the provided c-clip and wall mount box.
4.2.3 Motorised Damper
The motorised dampers should be  tted in line
with the  exible duct. Care should be taken to make
certain that all dampers/motors are of the same type.
MyZone 2 utilises time proportional modulation and
conducts a honing sequence on start up. Inconsistent
damper drive times will result in inaccurate damper
position and lower system performance.
4.2.4 Spill System Overview
The MyZone 2 ingenious spill system is the secret
behind how it is able to adjust  ow at each zone
without causing the system to operate outside the
acceptable pressure range. The MyZone 2 constantly
monitors the position of the dampers via the time
proportional damper positioning (TPDP) system.
When the spill set point is achieved, the MyZone 2
opens the damper selected to operate as the spill.

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.
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.
05 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.
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).

6.2 Spill Zone Conguration
 A spill zones(s) may be designated by turning
on one or more the of the spill DIP switches
on the MZWFCBT8-V2 Main Processor Module.
6.3 Initial Power Check
When power is applied to the system, the start-up
routine will drive all zone damper motors to the
fully open position, then all dampers will drive to
the appropriate position as dictated by the zone
status, and, if the zone is on, the system conditions.
 Connect the 24VAC power supply to the
MyZone 2 system.
 Check the main modules for fault LEDs (any
red LED indicates an excess current fault
on the output – generally a cable short).
6.4 System Conguration
The following system conguration steps must be
completed to ensure the system will operate correctly
with the motors supplied, and that the system safety
mechanisms are operating as intended. Using the
MZWFTP8-V2 System Conguration settings are
accessed by pressing the “Zones” icon from the
Home screen, from the “Zone Overview Screen” press
the “Settings” icon in the top right corner. System
conguration settings are password protected to
prevent accidental tampering. The password is “4321”.
