1. iZone Smart Home Systems
iZone Pty Ltd reserves the right to change or modify the design, specifications, software, hardware, firmware or Apps at any time without prior
written or oral notice. Images and functions in this manual should be considered as indicative only and may differ from the actual iZone touch
screen or Apps
Congratulations on the purchase of your iZone system.
iZone has been developed in Australia to provide affordable, reliable, automated control of your home or office.
iZone is a scalable control system that can provide basic air-side zoning all the way up to fully integrated air conditioning unit control with individual
room temperature control, occupancy sensing, lighting control, security, garden reticulation and power management.
You can begin your iZone journey with a basic system then add to it as funds become available without the need to replace what you have already
purchased.
The iZone family is shown on the diagram below. Please check with your contractor which parts are available in your area.

1.1. Airconditioning Control Systems
1.1.1. Design Consideration
All ducted air conditioning systems should have a percentage of air passing over the indoor coil at all times. This is a safety mechanism to protect
the ductwork and the AC unit.
If all the zone dampers in a system are closed then flexible duct could split or be blown off the spigots, or the indoor coil could ice up.
It is much less likely for the coils to ice up on modern AC units as they have in-built safety controls to prevent this occurring, but it is still good
practice to ensure airflow across the coil.
There are several ways of achieving this when designing a ducted air conditioning system. The final choice is the designers responsibility and this
manual only suggests various options that can be used.
Some options to achieve to ensure constant airflow across the indoor coil are detailed below:
➢Fixed Ducted Constant Zone
➢Standard Electronic Constant Zone
➢Dedicated Electronic Constant Zone
➢Bypass Electronic Constant Zone

7
1.1.1.1. Fixed Ducted Constant Zone
This is a relatively old fashioned way of achieving constant airflow across the coil. It requires the system to be designed with one zone that has no
zone damper fitted to it. This is normally the main living area in the home or a common area in an office building.
The downside with this configuration is that air will always be delivered to this area regardless of whether it is occupied or not. This reduces the
diversity of the system and may necessitate a larger AC unit to be installed, thereby increasing both the capital and running costs of the system.
In addition to this noise to this constant zone may increase when all other zones are closed.

8
1.1.1.2. Standard Electronic Constant Zone
Typically a zone damper would be fitted to the main living area in the home or a common area in an office building.
This zone can be used like any other zone but will be automatically overridden open if required by the system to maintain the minimum airflow over
the indoor coil.
With an iZone system you can select as many zones as you need to be electronic constants and they will activate and deactivate progressively as
required.
While superior to a Fixed ducted constant zone, it does have a number of short comings.
Most of the time the conditions in the standard electronic zone will be satisfactory however when required to operate to relieve pressure, conditions
(temperature) in this zone will drift and may become uncomfortable.
Individual room temperature control cannot be fitted to a standard electronic zone. Noise from the outlet may be higher when the electronic constant
is operating.

9
1.1.1.3. Dedicated Electronic Constant Zone
In this option an additional zone is installed into the system serving an unoccupied area such as a stairwell, passage or entry.
This zone is left in the closed position and will only open if required by the system.
With an iZone system you can select as many dedicated zones as you need.
The benefit of the dedicated electronic constant zone is that all habitable areas can have individual temperature control and if the electronic
constant is required to operate it will not affect the comfort of the occupants.
The downside of this type of electronic constant is that conditions in the corridor or stairwell may feel mildly uncomfortable while transiting through
them and the outlet in this area may generate some noise.

10
1.1.1.4. Bypass Electronic Constant Zone
In this option an additional zone is installed into the system looping from the supply air side of the A/C fan coil unit to the return air side of the A/C
fan coil unit.
This bypass zone is left in the closed position and will only open if required by the system.
The benefit of the Bypass Electronic Constant zone is that all habitable areas can have individual temperature control and if the electronic constant
is required to operate it will not affect the comfort of the occupants.
No common areas are affected by the operation of the bypass constant and there is no increase in noise when the bypass is operating.
In addition to this, the use of the bypass option increases the system efficiency as any conditioned air is kept within the system reducing the load on
the AC unit and assisting to cycle the AC unit off earlier. (If set up to control from the units return air sensor).
Our experience has shown that systems with individual zone temperature control that are designed and configured with a bypass electronic
constant zone and the AC unit, where possible controlled from “Zones” gives the best results.

1.1.1.6.1.1. 150 Zone only
iZone 150 Zone only is a basic low-cost zone only control system which is suitable for switching zones Open and Closed.
A summary of the features iZone 150 Zone only offers are listed below:
•Up to 6 zones available
•Zones air quantities can be balanced from the CECP controller (no need for separate manual balancing dampers)
•Zone airflows can be adjusted by the end user from the CECP controller
•Multiple CECP controllers can be added
•Zone temperatures can be controlled from CECP if iZone sensors are fitted to the system
•Label zone names from a standard library of names built into the controller
•Electronic constants can be set-up.
There is no facility to control the zones via WiFi . The AC unit module can be added to the iZone 150 to provide integrated AC unit and zone control.

1.1.1.6.1.1.2. Installation instructions
General installation instructions
1. The C150 can be installed on top of the indoor fan coil unit.
2. Do not run the blue network cables alongside 240 Volt wiring.
3. Always install zones in consecutive ports starting at Zone 1. The front of the C150 is marked with the zone port numbers.
4. Do not directly hard wire the CT24ACM into the AC unit’s power supply. This may void the warranty as it will require an electrician in the
event that repair of the iZone 150 system is required.
5. Connect Zone Damper Actuators (CZDA) to the zone ports using the RJ12 cables as shown.
6. Remove the tabs on the CEPC batteries to activate power to the controller
7. Only connect the power supply to the CT24ACM port after all components have been connected.
8. Initialise the system.
9. Configure the system.
