1.12 General installation instructions
1. The C325 and CEXT can be installed close to the indoor fan coil unit.
2. If any ireless sensor (CRFS) or ireless bridge (CB) is not ithin the range of the C325 then additional repeaters (CR) should be added
to help relay the signal from the field device to the C .
3. Do not run the net ork cables alongside 240 Volt iring.
4. When installing net ork cables do n all cavities or chasing net ork cables into alls, tape up and protect the RJ45 connector to avoid
damage to the connectors. Installation damage to cables is not covered under arranty.
5. Al ays install zones in consecutive ports starting at Zone 1. The C225 and CEXT are marked ith the zone port numbers.
6. Do not directly hard ire the CT24V into the AC unit’s po er supply. This may void the arranty as it ill require an electrician in the event
that a repair of the iZone po er supply is required.
7. Connect Zone Damper Actuators to the zone ports using the RJ11 cables as sho n.
8. Connect the Colour Touch Screens (CCTS) 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 ill need to connect a Net ork Extension Module Kit (CNEMK) to one of the iZone Net ports
on the CC using a short RJ45 cable.
9. If any zone is temperature controlled, connect a 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 blo conditioned air directly onto the sensors or touch screens.
11. Connect the AC unit control cable to the C225 / C325. See table 1.10 for details. (This cable is not supplied by Airstream.)
12. The building must be fitted ith a compatible WiFi modem.
13. If connecting the iZone system to a Home Automation system use the Ethernet connection on the bridge.
14. Only connect the po er supply to the CT24VAC port after all components have been connected.
15. Any existing or ne air conditioning units that require modification or additional boards to facilitate the correct operation of the iZone
system, is the installing contractors responsibility.
