General installation instructions

 

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

2.If any wireless sensor (CRFS) or wireless bridge (CL5B or 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.

3.Do not run the network cables alongside 240 Volt wiring.

4.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. Installation damage to cables is not covered under warranty.

5.Always install zones in consecutive ports starting at Zone 1. The C225 and CEXT are marked with the zone port numbers.

6.Do not directly hard wire the CT24ACE into the AC unit’s power supply. This may void the warranty as it will require an electrician in the event that a repair of the iZone power supply is required.

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

8.Connect the Colour Touch Screens (CCTSL or CCTSS) to the iZone Net ports using the RJ45 cables. If you are connecting more than 3 components requiring iZone Net ports to the system you will need to connect a Network Extension Module Kit (CNEMK) to one of the iZone Net ports on the C225 using a short RJ45 cable.

9.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. Secure the sensor in place by using reinforced aluminium tape.

10.When installing temperature controlled zones ensure the CCTS 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.  The supply air outlets to this room must not blow conditioned air directly onto the sensors or touch screens.

11.Connect the AC unit control cable to the C225 / C325.  See AC unit wiring connection section for details. (This control cable must be a shielded cable and is not normally supplied by Airstream.)

12.The building must be fitted  with a compatible WiFi modem. Contact Airstream for a list of approved and recommended modems.

13. If connecting the iZone system to a Home Automation system use the Ethernet connection on the bridge.

14.Only connect the power supply to the CT24ACE port after all components have been connected.

15.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.
