You can now use the Nest thermostat on all inverter type a/c & heat pump mini split systems. By installing a simple adapter device
you can get the full use of the Nest thermostat features without losing any functionality of your mini split system. The interface adapter install in about an hour and can be done by most DIY 's. The adapter works on most minisplit systems but send the company the model number of your system to be sure. I was working on the jobsite where 28 mini splits, half Samsung, half Mitsubishi were retrofitted with these adapters and Nest thermostats. They all worked just as they were supposed to.
The place was the Horizon Hotel in Palm Springs. The company can be found at Nestminisplitadapters.com nestminisplitadapters.com. Or on Ebay too.
The adapter works with all standard thermostats too, not just the Nest.
Happy trails,
