Description
The HVAC interface allows you to connect the indoor units of your Split, Multi-Split, or Mini-Split HVAC system to your Niko Home Control installation. Once connected, you can monitor and control your entire HVAC system via the Niko Home app. You can also create routines to automatically switch the air conditioning on and off to improve your comfort and optimise your energy consumption.
Operation
You can connect your entire HVAC system, within the following limits:
You can use only 1 CooLinkHub per Niko Home Control installation.
The HVAC interface can interact with a maximum of 10 indoor units.
You can create up to 10 zones per Niko Home Control installation. You can add multiple indoor units to the same zone.
Each HVAC indoor unit requires a CoolPlug that is compatible with the brand and type of your HVAC indoor unit.
To check compatibility, verify if the required connection terminals are present on your indoor unit, as described in Connecting the CoolPlug. If you are not sure, please contact customer services.
You can control your HVAC installation via:
Niko Home app
Digital black
Touch 3 (only for older systems that contain an HVAC thermostat)
You can also toggle the indoor unit on/off by pressing the button on the CoolPlug for 2-3 seconds.
