Why Wireless?

1. Split units: - WIRELESS Communication between outdoor & indoor

and multi-split units

2. Fan Coils and Mini-chillers - WIRELESS Communication between chiller and fan-

coils

- Have units work as a system

To offer installers a quicker and more cost effective solution on system

Benefit Of Wireless networking

• Total cost of installation and labor is less than wired solution

• Much lower installation time

• Easier to configure and avoiding wiring errors

• Easy to expand and easy to rearrange

• Lower impact to the end customer

• So simple that no specialist skill is required

• Great for Retrofit situations

• No wiring esthetic problems to solve

Wireless system optimized for building environment

• Works reliably in buildings: signals pass through walls, ceilings and other building materials

• Communication is secure: Encryption guarantees secrecy of information

• Ease of installation: No specialist knowledge required – no special configuration required

• No interference: Works at low radio power (0.5% of GSM mobile phone), accepted in hospital and other environments

Why ZigBee?• Low cost

• Low power (Maximum battery life)

• Network range (between 2 notes) ~ 40m

• Data transmission rate250kbps for 2.4GHz

• Highly reliableMesh and tree networking protocol Automatic retries and acknowledgementsCan avoid same frequency signal collision using

Carrier Sense Multiple Access (CSMA) technology

• Highly secureUtilizes AES 128-bit encryption

How ‘MESH’ NETWORKING works?

3. Devices automatically start communicating with nearby devices

4. Message pass through several nodes to the final destination

5. A single virtual network results, a ‘MESH’ network

1. Complex infrastructure layout includes walls, ceilings, staircases, etc.

2. Control devices are fitted with wireless technology

Application (Benefit)• Hotel / Office / Building energy

management

Major operating expense for hotel

Centralized HVAC management allow to make sure empty rooms are not cooled

Retrofit capabilities

Battery operated control panel can be placed for convenience

Interoperability with other devices (lighting, BMS system, security system…) with Zigbee protocol

Easy installation, replacement, expand
