Coolink’s Interface is compatible with Daikin VRV, Panasonic / Sanyo and Toshiba VRF indoor units. In the future indoor units of HVAC systems from Mitsubishi, Hitachi, Fujitsu and others will be supported as well.
Seamless Easy integration with Home Automation Systems and PC applications
Interfacing Home Automation Controllers with CooLink is a simple and straightforward task requiring only common ASCII commands over RS232 or simple registers read /write operands over RS485 to fully comply with ModBus RTU specifications.
Same RS232 Interface for all VRV/VRF HVAC Systems
All CooLink models provide the same RS232 interface for all VRV/VRF HVAC Systems. So for instance, a home automation application, where a Daikin VRV indoor unit is connected via CooLink, will function exactly the same way for as Panasonic VRF, Sanyo VRF, Toshiba VRF etc’. No special interface adaptation is required to migrate from one CooLink type to another.
Full Control over Indoor Units Operation
Control over indoor units includes the following functions: 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. CooLink allows simultaneous control of up to 8 indoor units.
Connectivity and Power Supply
CooLink is connected to the indoor unit’s communication, while power supply is external. An external wall mounted 220/110v power supply unit and adaptor are supplied with the unit. Future designs won’t require any additional power supply unit.
Indoor units Monitoring and Diagnostics
Coolink allows the monitoring and diagnostics of 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 and EV opening.
Proprietary ASCII, ModBus RTU.
Plug and Play device
The system is ready to work and no additional configuration set up will be required after connecting the wiring, supplying the power and defining addresses of indoor units.
New Firmware can be uploaded via RS232 port. No need to open the unit to change its’ functionality.
