iZone 430 & 435 is an integrated air conditioning unit and zone controller that uses a Nexus touch screen (CCTSL#) for the graphic user interface

Zones can be temperature controlled by adding iZone sensors and an induct temperature sensor

The iZone 435 is supplied with an iZone Bridge, the user can control the AC and zones via Wi-Fi from their smart phone or tablet. Other iZone automation products such as lighting, irrigation, garage door control etc can also be added and controlled

iZone 430 can be configured as 0-8 zones or 9-14 zones

1x C225: CPU

1x CT24ACE: 24v Power Supply

1x CFC12S: 12m Cat5e Cable

1x CCTSL#: Nexus or Nexus+ Touch Screen

1x C325#: AC Unit Interface (Brand Specific)

1x COCB: Smart Hub (Optional Extra)

1x CEXT: Zone Extender (Optional Extra)

1x CDTS: In-Duct Temperature Sensor (Optional Extra)

1x CR: Repeater (Optional Extra)

#x CRFS#: Wireless Temperate Sensors (Optional Extra and Number Supplied)

1️⃣ The C225, C325# and CEXT can be installed close to the indoor fan coil unit

2️⃣ If any wireless sensor (CRFS#) or wireless bridge (COCB) is not within the range of the C225 then additional repeaters (CR) should be added to help relay the signal from the field device to the C225 and the bridge

3️⃣ Do not run the cat5e cables alongside 240 Volt wiring

4️⃣ When installing network cables down wall cavities or chasing network cables into walls, tape up and protect the RJ45 connector to avoid damage to the connectors

5️⃣ Always install zones in consecutive ports starting at Zone number one (1)

The C225 and CEXT are marked with the zone port numbers

6️⃣ Do not directly hard wire the CT24ACE into the AC unit’s power supply

7️⃣ Connect Zone Damper Actuators (CZDA) to the zone ports using the RJ12 cables as shown in the Wiring layout diagrams

8️⃣ Connect the Colour Touch Screens (CCTSL# or CCTSL#+) to the iZone Net ports using the RJ45 cables

9️⃣ If any zone is temperature controlled, connect an in Duct Temperature Sensor (CDTS) to the CDTS port

Install the sensor into the supply air duct upstream of all dampers, then secure the sensor in place by using reinforced aluminium tape

1️⃣ 0️⃣ When installing temperature controlled zones ensure the CCTSL# or sensor for the associated zone is installed in a location that is representative of the temperature in the room / zone

The sensor should be installed at approximately 1600mm above the floor and should not be subject to draughts, direct sunlight or heat from equipment such as computers, TV screens etc

1️⃣ 1️⃣ Connect the AC unit control cable to the C225 / C325.

See AC unit wiring connection section for details - C325#: AC Unit Interface - Install Guides

1️⃣ 2️⃣ The building must be fitted with a compatible Wi-Fi modem

For a list of approved and recommended modems - COCB - Smart Hub - Install Guide

1️⃣ 3️⃣ If connecting the iZone system to a Home Automation system use the Ethernet connection on the bridge - iZone API Integration - Install Guide

1️⃣ 4️⃣ Only connect the power supply to the CT24ACE port after all components have been connected

1️⃣ 5️⃣ Any existing or new air conditioning units that require modification or additional boards to facilitate the correct operation of the iZone system, is the responsibility of the installing contractor
