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
