C150: 6 Zone CPU - Install Guide




The C150 module provides the main processor and communication for the C150-155 six zone control and integrated iZone control

Zone ports:

Connect the RJ12 cables from the damper motors here. Start at zone 1 and connect sequential ports. i.e. 1,2,3,4.....etc

Transformer connection:

Connect the iZone transformer here. Part number CT24ACM

C150 / CEPC pairing button:

The pair button can be used to pair wireless CEPC controllers as well as wireless sensors CRFS and iZone Wi-Fi bridges (COCB)

AC unit module connector:

When used for integrated AC / Zone control an AC module is connected to the C150. This module is a C325. Each different brand of AC unit has its own unique C325 module. To view assembled product please click on this link

RF antenna:

433Mhz antenna is screwed on here. This is used for communication with wireless sensors CRFS and Wi-Fi bridges COCB

AC unit control cable connection:

Connect the shielded, 2 core cable from the AC unit to the C150 here. This is a spring loaded wire terminal see here for specifications

Supply air temperature sensor port:

The supply air sensor is plugged into the C150 here. The supply air sensor is only need for systems that have zone temperature controls

The C150 can be installed on top of the indoor fan coil unit

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

Do not run the network cables alongside 240 Volt wiring

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

Always install zones in consecutive ports starting at Zone 1. The front of the C150 is marked with the zone port numbers

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

Connect Zone Damper Actuators (CZDA) to the zone ports using the RJ12 cables as shown

When installing temperature controlled zones ensure the sensors 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 CEPC

Connect the AC unit control cable to the C150 as per the instructions for your brand of AC unit

Remove the tabs on the CEPC batteries to activate power to the controller

Pair the CEPC to the C150, see here for a guide

Only connect the power supply to the CT24ACM port after all components have been connected

To access the C150 system via our iZone Home App, the building must be fitted with a compatible Wi-Fi modem. Contact iZone for a list of approved and recommended modems

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


All new or modified systems must be initialised prior to system configuration

To initialise the system remove the power from the C150 module, wait 15 seconds and restore power to the C150 module or by turning the isolator / breaker that powers the iZone system off and back on

The time to initialise the system will vary depending on the number of motors connected
