1 InstallatIon GuIdelInes
The following guidelines are intended for the installation of Livezi Digital and Inverter air
conditioning units used on domestic and commercial installations. Only suitably qualied
trade personnel should carry out installations of Split or Package Air Conditioning systems.
Full compliance with the local codes and regulations, which govern the installation of the
equipment, is the responsibility of the installer.
Before installation, the electrical power should be checked to determine if adequate power is
available with correct voltage to the site. The position of the equipment, after a survey of the
building and the duct layout, should meet the following criteria.
1.1 Electrical
• All wiring by the installer must comply with local Energy Authority wiring rules. To make
the correct connection a 240V 50Hz supply must be available in the case of single-phase
units and a 415V 50Hz supply must be available in the case of three phase units.
• During transportation the units electrical connections may become loose, therefore it is the
installers / electrician’s responsibility to make sure that all electrical connections are secure
or warranty will be void.
• Field or installation wiring must be connected as per the connection diagram to ensure the
unit performs as it is designed (Refer to Appendix A).
• Installer / electrician is to ensure that when an external overload device is tted, it
be calibrated or set to the maximum amp draw on the rating plate of the motor it is
controlling.
2 system overvIew
Livezi Connect delivers unprecedented levels of comfort and consumes signicantly less energy
than traditional concealed residential ducted systems. It achieves this by eliminating waste.
Traditional systems have a xed indoor airow and although they modulate the refrigerant
ow they cannot make their output proportional to the heat load of the home without dramatic
shifts in the sensible heat ratio. Livezi maintains a consistent sensible heat ratio by controlling
indoor airow in concert with refrigerant ow.
Livezi controls all three comfort drivers (velocity, humidity and temperature). Livezi connect
eliminates over cooling/ heating through the use of Air Stream Mapping (proprietary
algorithm). Energy efciency is managed through the use of Four Point Modulation (proprietary
algorithm). The system has the exibility to provide any combination of temperature and
velocity targets for each zone.
6
3 Control system
The air conditioning plant and control system contains no user serviceable parts. Installation,
service and maintenance of these components should be carried out by a suitably qualied
technician.
The control circuits for the indoor and outdoor units carry voltages ≥ 240 VAC which can
cause serious injury or death.
3.1 Livezi Chatterbox
Livezi chatterbox is an easy to use application that will run on any iOS device (iPad, Ipod,
Iphone). It takes advantage of the large canvas associated with the iPad to provide an intuitive
user interface.
3.2.1 Chatterbox HVAC
Livezi chatterbox creates a page for each zone within the home.
It displays zone specic information in a user friendly format enhancing
the Livezi experience.
3.2.2 Chatterbox LTE
Chatterbox LTE provides the same easy to use interface for lighting
control.
3.2.2 Chatterbox NRG
Chatterbox NRG provides the same easy to use interface for energy
management.
3.2.2 Chatterbox LOK
Chatterbox LOK provides the same easy to use interface for security.
7
3.2 LiveziConnectvariableairowmultizonecontroller
The Livezi Connect control system is a variable air volume (VAV) system with a 24 volt AC
supply.
The Livezi Connect control modules (3) monitor the temperature for each zone from the
sensor mounted in each zone touchpad (5). The zone dampers (4) open and close depending
on whether or not the air being supplied by the HVAC plant (1) & (2) will assist the zone in
maintaining the set temperature.

3.2.1 Connect Main Processor Module
The main processor module is best installed on or near the indoor
unit. Maintain a minimum distance of 300 mm from sources of EMI
such as the indoor fan motor.
3.2.2 EXP8 Zone Expansion Module
The zone expansion module must be connected to the right hand
side of the main processor module. A separate 24 VAC power supply
is required (Refer to Connection Diagram).
3.2.3 EXP12 Zone Expansion Module
The zone expansion module must be connected to the right hand
side of the EXP8 module. A separate 24 VAC power supply
is required (Refer to Connection Diagram).
3.2.4 PARX Zone Expansion Module
The PARX expansion module must be connected to the right hand
side of the main processor module. A separate 24 VAC power supply
is required (Refer to Connection Diagram).

3.2.3 Zone Touchpads
The zone touchpads house the zone sensors and must be mounted
within the area controlled by the corresponding motorised damper.
The ideal position is 1.5 m off the oor in the return air path. Care
must be taken to avoid solar radiation, wall cavity drafts and other
heat sources.
The LCD zone touchpads allow the user to adjust various aspects of the indoor climate. By
default access to all control functions is available from all LCD touchpads.
Access to some control functions from individual touchpads may be limited via hardware DIP switch
settings during installation. These DIP switches are located on the back of each LCD zone
touchpad.
If access to a function has been limited the LCD touchpad will respond with a beep only.

3.2.4 Motorised Dampers
The motorised barrel dampers must all have the same motor type,
and should be tted in line in the exible duct.
3.3 Control Wiring
• All control wiring to touchpads and motors is by RJ12 type connectors, with the exception
of the 24 VAC supply to the Livezi Connect main modules.
Refer to Appendix B for control cable crimping instructions.
• Shielded cable is recommended for all data connections to minimise the possibility of
external interference.
• Data cables are to be kept the maximum practical distance from any LV power supply
cables ≥ 240 volts (Minimum distance 300 mm).
• Maximum cable length is not to exceed 50 m.
Suggested cabling: Livezi supplies and recommends the following cable:
RM-CAB-6-100 - six core at cable for damper motors
RM-CAB-S-100 - ve core + shield at cable for all data connections and touchpads.

4 ConneCt CommIssIonInG steps
4.1 Beforeconnectingpower
If the system has more than four zones, ensure that the Connect MPM and expansion modules
are rmly connected and xed in place so they cannot come apart.
THESE MODULES MAY BE DAMAGED IF THEY ARE SEPARATED WHILE POWER IS APPLIED
TO THE SYSTEM.
Ensure that all touchpads and motors are connected as per the connection diagram supplied.
DO NOT CONNECT SENSORS TO MOTOR OUTPUTS. SENSORS MAY BE DAMAGED IF
POWER IS APPLIED IN THIS CASE.
4.1.1 Add MotorSet zones
Livezi connect is plug and play and will automatically detect present zones on boot up. It is
possible to make a zone present without a room touchpad or controller present. Each module
has a four DIP switch package. To make a zone present without a temperature sensor change
the state of the corresponding DIP to on.
4.2 InitialPowerOn
When power is applied to the system, the start-up routine will drive all zone damper motors
to the fully open position. Check the main modules for fault LEDs (any red LED indicates an
excess current fault on the output - generally a cable short)
4.3 SetZoneProles
Each zone on the Connect can be tailored to suit the individual requirement of the space it
controls. Zone Proling includes a maximum open position on the damper and an airow
range.
4.3.1 SetZoneMaximumOpenProle
Each zone is assigned a maximum open damper position. This value represents the maximum
travel in the open direction. The default vale for each zone is 100%. The minimum position can
be set for active zones but this is a global value and is part of System Conguration (5.4).
Press or to select the target zone.
1. Press and hold both and for 10 seconds until the LCD display reads MaxPos #
on the top line (#= current zone number).
2. Use or to adjust the maximum open position, then press
SET
to save and
proceed to airow prole.
4.3.2 SetAirowProles
Each zone on the Connect is assigned a virtual value called the airow prole. This value
represents the nominal maximum airow to each zone when fully open. The default (and
minimum) value for all zones is 200 L/s. Adjusting the airow proles enables the system to
compensate for differences in zone size. Changing the airow prole for a zone effects the
balance of the airow management algorithm.
For more information on airow management refer to Appendix C.
3. The LCD display reads #)A/Flow
4. Use or to adjust the airow prole value, then press
SET
to save and exit.
5. Repeat for each zone as required.

4.4 SystemConguration
The following system conguration steps must be completed to ensure the system will operate
correctly with the motors supplied, and that the system safety mechanisms operate as intended.
4.4.1 Set Cooling Performance
The Cooling Performance parameter provides additional energy savings by reducing
compressor run time. The ingenious design of the Connect VAV is such that some cooling can
still be achieved through thermal redistribution and heat targeting.
1. Press or to select the global screen. The display should read Active:x
(where x is the number of zones currently ON).
2. Press and hold both and for 10 seconds until the LCD display reads Cool DB
on the top line.
3. Use or to alter the cooling delay setting, then press
SET
to save and proceed to
the next step.
4.4.2 Set Heating Performance
The Heating Performance parameter provides additional energy savings by reducing
compressor run time. The ingenious design of the Connect VAV is such that some heating can
still be achieved through thermal redistribution and heat targeting.
1. The display should now read Heat DB on the top line.
2. Use or to alter the heating delay setting, then press
SET
to save and proceed to
the next step.
4.4.3 Set Motor Type
The Livezi Connect utilises a time proportional damper positioning algorithm.
Livezi offers three motors with different drive speeds for use with Connect:
The Livzi 20* has a motor drive time of 20 seconds (default).
The ADVAN16 has a motor drive time of 16 seconds.
The Beli100 has a motor drive time of 100 seconds.
The Beli 45 has a motor drive time of 45 seconds.
The Mex16 has a motor drive time of 45 seconds.
The Poly16 has a motor drive time of 16 seconds.
The Aadit16 has a motor drive time of 16 seconds.
NOTE: All motors connected to a single system must be the same type.
1. The display should read Mot Type. The default motor type is Livezi20.
2. Use and to alter the motor type if required, then press
SET
to proceed to the
next step.
4.4.4 Set Minimum Ventilation Parameters
The Connect System can be programmed to allow a minimum airow to all zones that are ON. This
is adjustable from 0 to 30% open and defaults to zero. This value effects all ON zones equally.
The zone motors will close fully when the zone is turn turned OFF.
1. The display should now read Min Vent on the top line.
2. Use or to alter the minimum ventilation setting and press
SET
to proceed to the
next step.
