CoolLink
RS232/RS485 Interface Adapter for Residential Air Conditioners

General Description

CooLink is a versatile bridge device that allows to control single-split & multisplit air conditioning systems by Home Automation control systems. Exposing simple interface over RS232 or RS485 communication line, CooLink gains user application full control over air conditioning system parameters, helping simultaneously integrating it with other home control systems, such as lighting, curtains etc. CooLink enables several interfaces for air conditioning control, such as: a proprietary ASCII commands protocol over RS232, same proprietary ASCII commands protocol using RS485 or standard Modbus RTU protocol on RS485 communication line.

- Compatible with communication line to the local controller
- Provides Simple RS232/RS485 Interfaces
- Can be used with Home Automation Controllers or PC
- Customizable for specific user applications
- Field Upgradable

Features

	Compatible with: Currently Coolink Interface is compatible with Sanyo and Toshiba VRF indoor units. In the future, the range will be exytended to Daikin, Mitusbishi, Hitachi and Fujitsu air conditioning systems.
	Easy to integrate with Home Automation Systems and PC applications CooLink Interface is very simple and straightforward. Implementation of software modules (ASCII or ModBus) to support CooLink is not complex at all.
	Unified RS232 Interface All CooLink products impose unified interface for all manufacturers. It means, for example, that home application working for Daikin will work exactly the same way for Sanyo, Toshiba, Mitsubishi or other air conditioning systems. No special adaptation will be required to migrate from one CooLink to another.
	Full Control over Indoor Units Operation On/Off control, Cool, Heat, Fan, Dry mode selection, Set Temperature Control, Fan Speed Control, Swing Control (for wall mounted and cassette indoor units), Filter Reset Sign, Simultaneous control of up o 8 indoor units
	Connection and Power supply CooLink is connected to the communication line of the indoor unit. It doesn't require any additional power supply.
	Indoor Units Monitoring and Diagnostics Failure Alarms, Set point temperature, Operation status (on/off) Operation mode (cool/heat/fan/dry), Fan speed (high/low), Filter sign, Swing. Liquid and Gas temperatures, EV opening.
	Interfaces CooLink enables interfacing the indoor unit by: Proprietary ASCII protocol over RS232, Proprietary ASCII protocol over RS485, ModBus RTU over RS485
	Plug and Play device No additional configuration required after connecting the wiring, supplying the power and defining address of the indoor units, the system is ready to work.
	Field Upgradable New Firmware can be uploaded via RS232 port. No need to open unit to change it's functionality.
