1.4 Installation instructions
1.
The CCPU can be installed on top of the indoor fan coil unit.
2.
Do not run the blue network cables along side 240 Volt wiring.
3.
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.
4.
Always install zones in consecutive ports starting at Zone 1. The back of the CCPU is marked with the zone port numbers.
5.
Do not directly hardwire the CT24V 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 system is required.
6.
Connect Zone Damper Actuators (CZDA) to the zone ports using the RJ11 cables as shown.
7.
Connect the Colour Touch Screens (CCTS) to the CCTS ports using the RJ45 cables. If you are connecting more than 3 CCTS to the
system you will need to connect a Network Extension Module (CNEM) to the CCPU using a short RJ45 cable.
8.
If any CCTS is being used for zone temperature control 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.
9.
Connect the power supply to the(CT24AC) port.
10. When installing temperature controlled zones ensure the CCTS for the associated zone is installed in a location that is representative of
the temperature in the room / zone . The CCTS 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 touch screen, as the temperature sensor is located in the CCTS.
