591.32 General installation instructions1. The CM225, CM325 and CMEXT can be installed close to the indoor fan coil unit.2. If any wireless sensor (CRFS) or wireless bridge (CML5B) is not within the range of the CM225 then additional repeaters (CR) should beadded to help relay the signal from the field device to the CM225 and the CML5B.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 avoiddamage to the connectors. Installation damage to cables is not covered under warranty.5. Always install zones in consecutive ports starting at Zone 1. The CM225 and CMEXT are marked with the zone port numbers.6. 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 eventthat a repair of the Myzone power supply is required.7. Connect Zone Damper Actuators (CZDA) to the zone ports using the RJ11 cables as shown.8. Connect the Colour Touch Screens (CMCTS) to the Myzone Net ports using the RJ45 cables. If you are connecting more than 3components requiring Myzone Net ports to the system you will need to connect a Network Extension Module Kit (CNEMK) to one of theMyzone Net ports on the CM225 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 thesupply air duct upstream of all dampers. Secure the sensor in place by using reinforced aluminium tape.10. When installing temperature controlled zones ensure the CMCTS or sensor for the associated zone is installed in a location that isrepresentative of the temperature in the room / zone . The sensor should be installed at approximately 1600mm above the floor andshould not be subject to draughts, direct sunlight or heat from equipment such as computers, TV screens etc. The supply air outlets tothis room must not blow conditioned air directly onto the sensors or touch screens.11. Connect the AC unit control cable to the CM225 / CM325. See table 1.30 for details. (This control cable must be a shielded cable and isnot supplied by Reece.)12. The building must be fitted with a compatible WiFi modem. Contact Reece for a list of approved and recommended modems.13. If connecting the Myzone system to a Home Automation system use the Ethernet connection on the bridge.14. Only connect the power supply to the CT24VAC 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 Myzonesystem, is the responsibility of the installing contractor. |
