General Installation Rules

1. The Myzone CPU (C225) and A/C Unit Module (C325) can be installed close or on the indoor fan coil unit.

2. Do NOT directly hardwire the 240V/24V transformer into the A/C units power supply. The transformer requires its own power supply.

3. Do NOT run the A/C unit control cables or RJ45 cables alongside 240V wiring.

4. Must use two-core, shielded data cable with a minimal thickness of 0.75mm for the A/C unit control cable.

5. Connect the Nexus or Nano touch screens to the Myzone net ports on the Myzone CPU using the supplied RJ45 cables.

6. When installing RJ45 cables down wall cavities or chasing through walls, protect the RJ45 connectors with tape to avoid damage, installation damage to cables is not

covered under warranty.

7. All zone motors used on a system must be the SAME brand.

8. Connect all zone damper motors using RJ12 cables.

9. Always install zones in consecutive ports starting at Zone 1. The Myzone CPU (C225) is marked with zone numbers.

10. If any zone is temperature controlled, connect a supply air in-duct temperature sensor to the CDTS port on the Myzone CPU (C225). Install the sensor into the supply air

plenum. Secure the sensor in place using reinforced aluminium tape.

11. When installing temperature controlled zones, ensure the 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 in the room must not blow conditioned air directly onto the sensor.

12. If any wireless sensor or wireless bridge is not within range then additional signal repeaters can be added to help relay the signal.

13. Myzone Wi-Fi Bridge Ethernet connection must be plugged directly into the customers modem/router.

14. Only connect power supply to Myzone CPU (C225) ater all components have been connected.

1. Install the ducted air conditioning unit, zone damper motors, ﬂexible duct and grilles as per manufacturer’s instructions and in accordance with relevant

Australian Standards.

2. NOTE: For full wiring details, please refer to pages 13-27.

Hardware Installation

Connect the CPU (CM225) and the relevant A/C unit module together (Installation of the A/C unit module is only applicable to system set-ups that require A/C Unit

Control) (CM325# – Refer to module list for correct module). Take care ensuring that the A/C unit module pins are installed straight and direct.

3. Connect the supplied blue RJ45 cable to the “Myzone Net” port at the top of the Myzone CPU (CM225), run the other end of the cable to the Myzone Nexus/Nano Tablet.

4. Connect the blue RJ12 zone motor cables (sold separately) in consecutive ports starting at Zone 1 on the CPU (CM225) The CPU (CM225) is marked with zone numbers.

All zone motors must be the same brand.

5. Connect the red supply air sensor (CDTS) to the supply air temp. port on the Myzone CPU (CM225) and place the temperature sensor inside the supply air plenum/duct

and secure sensor with reinforced aluminium tape. NOTE: A supply air sensor is only required to be installed if there are individual temperature controlled zones. ON/OFF

zone control does NOT require a supply air temperature sensor.

6. Run twin-shielded data cable from the A/C unit control cable terminals on the Myzone CPU (CM225) to the A/C unit indoor board (see pages 28-43 for detailed wiring

instructions on A/C unit brands) Must use minimum 0.75mm signal cable. NOTE: Only run twin-shielded data cable if A/C unit control is required.

7. Plug the 240V power plug on the transformer into a power source. Plug in the 24V transformer plug into the side of the Myzone CPU (CM225) to provide power to the CPU.

Ensure to run a separate power supply for the 240V plug o the transformer. DO NOT take power from the A/C unit.

8. Ater System Initialisation has completed, conﬁgure the Myzone control to your application (see conﬁguration instructions on pages (page 76).

9. Pair Wireless Sensors to the system as per instructions in conﬁguration on page 81 and mount according to general installation rule 11.

10. Pair Wi-Fi Bridge to the system as per instructions in conﬁguration on page 72.

The above general installation instructions are applicable to installation conﬁgurations pictured on pages 28-43, any other conﬁgurations will require dierent/extra

installation procedures (refer to installation wiring layout and index for assistance).

System Design Considerations

Designing the Correct Constant Zone

All ducted air conditioning systems should have a percentage of air passing over the indoor coil at all times. This is a safety mechanism to protect the

ductwork and the A/C unit.

There are several ways of achieving this when designing a ducted air conditioning system.

i. Fixed Ducted Constant Zone

A ﬁxed duct constant zone requires the system to be designed with one zone that has no zone damper ﬁtted to it. This is normally a large common area (e.g. main living area).

The downside with this conﬁguration is that air will always be delivered to this area regardless of whether it is occupied or not. This reduces the eciency of the system and

does not allow for modulating temperature control in the zone.

ii. Electronic Constant Zone

This option requires the system to be designed with one zone that has a zone motor ﬁtted to it, which will automatically open if all other zones are closed. With electronic

constants there are three options available as follows:

a. Standard electronic constant zone

Typically a zone damper would be ﬁtted to the main living area in the home or a common area in an oce building. This zone can be used like any other zone but will be

automatically overridden open if required by the system to maintain the minimum airﬂow over the indoor coil. With a Myzone system you can select as many zones as

you need to be electronic constants and they will activate and deactivate progressively as required. Standard electronic constant zone is only Open/Closed.

b. Dedicated electronic constant zone

In this option an additional zone is installed into the system serving an unoccupied area such as a stairwell or hallway. This zone is let in the closed position and will

only open if required by the system. With a Myzone system you can select as many dedicated zones as you need. The beneﬁt of the dedicated electronic constant zone is

that all occupied areas can have individual temperature control and if the electronic constant is required to operate it will not aect the comfort of the occupants.

iii. Bypass Electronic Constant Zone

In this option an additional zone is installed into the system looping from the supply air side of the A/C fan coil unit to the return air side of the A/C fan coil unit. This

bypass zone is let in the closed position and will only open if required by the system. The beneﬁt of the Bypass electronic constant zone is that all occupied areas can

have individual temperature control and if the electronic constant is required to operate it will not aect the comfort of the occupants. No common areas are aected by

the operation of the bypass constant and there is no increase in noise when the bypass is operating. In addition to this, the use of the bypass option increases the system

eciency as any conditioned air is kept within the system reducing the load on the A/C unit and assisting to cycle the A/C unit o earlier. (If set up to control from the units

return air sensor).

We recommend that all systems with individual zone temperature controls are designed and conﬁgured with a bypass electronic constant zone and where possible control

the A/C unit from "Zones" (see Fig C04).
