Connect the CoolPlug to the CooLinkHub via a wired or wireless connection. Optional: Connect the Wired Remote Controller (WRC) to the connector on the cable supplied with the CoolPlug.

Programming

Configure the CooLinkHub and CoolPlugs via the Niko Home Control programming software. Create a virtual HVAC thermostat for each zone and link it to the indoor unit(s) using the routine HVAC per thermostat; see https://guide.niko.eu/en/smnhc2/lv/hvac-per-thermostat.

After uploading the new configuration, the virtual HVAC thermostat(s) will appear in your Niko Home app in the Control tab. By editing this control, you can easily adjust the default settings for various programs and modes.
