1 InstallatIon GuIdelInes
The following guidelines are intended for the installation of Livezi Digital and Inverter air
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 unit’s electrical connections may become loose, therefore it is
the installer’s / 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).
be calibrated or set to the maximum amp draw on the rating plate of the motor it is
controlling.
2 system overvIew
Livezi Z-Plus provides a central control point from which system capacity can be adjusted in up
to eight individual zones (rooms). Like most residentially orientated concealed split ducted air
conditioning control products, the Z-Plus provides four main system modes (Cooling, Heating,
narrow range of fan speeds as the return air temperature approaches the target temperature
requirement of individual rooms.
controller. The aggregated value is then passed through to the supply air fan controller, and
is to allow localised adjustment of system capacity based on comfort; avoiding the shortfall
apparent on the day of commissioning.

cause serious injury or death.
3.1 Z-Plus System Overview
Livezi Z-Plus provides an unprecedented level of capacity adjustment at each zone. Livezi
Radical Flow, Digital Inverter and Dual Inverter systems automatically adjust refrigerant mass
3.1.1 Z-Plus Main Processing Module
The Z-Plus MPM provides unit support and the ability to control up to eight zones. Two
touchpad ports are provided.
3.1.2 Z-Plus Touchscreen Controller
Livezi Z-Plus utilises a mixture of hard and soft buttons to provide control over the air-
conditioning plant and individual zones.
3.1.3 Z-Plus Touchpad Expansion Module
Livezi Z-Plus can have limitless touchpads connected through the use of touchpad expansion
input. Touchpad sensors are disabled when expansion is used. Care should be taken not to

3.2 Livezi Z-Plus Component Positioning
The Livezi Z-Plus control system is a unit control and zone positioning system with a 24 volt AC
supply.
The Livezi Z-Plus Main Processing Module (3) provides a central connection point for the air-
conditioner, zone dampers and user touchpads. The Z-Plus is factory set to take corrective
action based on the return air temperature. The sensor location can be altered to use the
touchpad sensor or an average of any connected sensors. The touchscreen controller (5)
provides the user interface. From the touchscreen controller all system parameters can be
adjusted. The zone dampers (4) can be adjusted to meet the demands of the room. Unlike
the touchpad (5). The air conditioning plant (1) & (2) is connected to the MPM (3).

3.2.1 MPM DIP Switch Functions
The MPM DIP switch defaults are suitable for the majority of installations. On occasion it may
assist the operation of the system to activate some or all of the additional functionality built in
to the DIP selection. The table below details the effect each combination of DIP positions will
have on system performance.

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.
Data cables are to be kept the maximum practical distance from any LV power supply
Maximum cable length is not to exceed 50 m.
Suggested cabling: Livezi supplies and recommends the following cable:

INSTALLER TIP: Make up a short cable and perform steps 5.1 to 5.5 with the LCD touchpad
in the ceiling space next to the main modules.
5.1 Before Connecting System Power Supply
1. Ensure that all modules are correctly mounted and the power supply is connected
properly.
2. Ensure that all touchpads and motors are connected as per the connection diagram
supplied.
DO NOT CONNECT Z-PLUS TOUCHSCREEN TO MOTOR OUTPUTS.

the zone status and set parameters.
1. Connect the 24 VAC power supply to the MyZone system.
2. Check the main modules for fault LEDs (any red LED indicates an excess current fault
on the output - generally a cable short).

5.4.1 Set Present Zones
Z-Plus Touch can adjust its display so that only present zones appear. Press the + or - soft
keys until the appropriate number of zones is displayed.
5.4.2 Set Motor Time
Z-Plus Touch utilises a time proportional damper positioning algorithm. For the system to
function correctly all zone damper motors must be the same type.
Livezi offers 2 motors with different drive speeds for use with Z-Plus:
The Livezi motors require the motor drive time to be set to 16 seconds (default).

5.4.3 Maximum Capacity
Z-Plus provides an ability to adjust the peak system capacity to match perfectly the peak load.
Most residential systems are sized on the peak cooling daytime load. If the standard sizing
calculation has been used, set the Maximum Capacity to equal the area used in the capacity
calculation.
Z-Plus includes the ability to group zones together so they can be controlled simultaneously.
The favourites will appear at the end of the zone names and include individual time clock
the top of the screen the Favourites name will be displayed (default is Fav a ~ Fav d). Group
zones by pressing the button beside each zone name.
5.4.5 Calibrate Touch
Z-Plus Touch utilises a four wire touchscreen. After extended use it may be necessary to re-
calibrate the display. Calibration is completed in the factory before shipping so this process
does not form part of the system commissioning procedure. If calibration is necessary activate
5.4.6 Service Timer
Z-Plus Touch incorporates a service timer that logs the run time of the indoor fan. Programmed
maintenance is required to satisfy the warranty coverage conditions and the Service Timer is
an excellent way of scheduling programmed maintenance. A custom contact number can be
added so that when a service is required the contact details are available to the home owner.
