CooLink

Product catalog summary

Overview: CooLink is a bridge device designed to integrate single-split and multi-split air conditioning systems with home automation systems. It provides control over air conditioning parameters via RS232 or RS485 communication lines, facilitating integration with other home systems like lighting and curtains.

Interfaces and Protocols: CooLink supports several interfaces for air conditioning control, including a proprietary ASCII commands protocol over RS232 and RS485, as well as the standard Modbus RTU protocol on RS485.

Compatibility: The device is compatible with systems from Daikin, Mitsubishi Electric, Sanyo, Toshiba, and potentially Hitachi and Fujitsu in the future.

Features: CooLink allows for full control over indoor unit operations, including on/off control, mode selection (cool, heat, fan, dry), temperature setting, fan speed control, swing control, and filter reset. It supports simultaneous control of up to 8 indoor units and group operations.

Installation and Upgrades: CooLink is a plug-and-play device that requires no additional configuration after setup. Firmware updates can be performed via the RS232 port using a PC or laptop.

Monitoring Capabilities: The device provides monitoring features such as failure alarms, set point temperature, operation status, fan speed, and diagnostics for liquid, gas, return air temperatures, and expansion valve opening.

Unified Interface: CooLink offers a unified RS232 interface across all manufacturers, ensuring that applications developed for one brand will work seamlessly with others without requiring special adaptations.
