The MRCOOL Smart Wi-Fi Mini-Stat is a touch-screen controller for MRCOOL ductless mini-splits that links to the SmartHVAC app over Wi-Fi. Its Comfy Max mode learns your routine and adjusts setpoints, fan speed and mode to prevent overheating or overcooling, and it measures and displays room temperature and humidity.
Set it on its stand where you sit or mount it on the wall, then manage schedules and voice control from your phone. That is MRCOOL's Smart Wi-Fi Mini-Stat.

About MRCOOL
MRCOOL designs heating, cooling and water-heating equipment from its home base in Hickory, Kentucky. The range runs from DIY ductless mini-splits, built around MRCOOL's patented pre-charged Quick Connect line sets, through contractor-installed mini-splits, central split systems, packaged units and gas furnaces, to HeatWise water heaters and CoolBlade HVLS fans for warehouses and shops.
The Smart Wi-Fi Mini-Stat is MRCOOL's wall or tabletop controller for its ductless mini-splits, run through the SmartHVAC app. It sits apart from the MST07 Smart Wi-Fi Thermostat, which is built for 24V central systems with a C wire, and it is compatible with MRCOOL Link, the platform that pairs a heat pump with a furnace or boiler.
