Smarter Comfort Starts with the MRCOOL® MST07 Smart Thermostat
The MRCOOL® MST07 Smart Thermostat is designed to make controlling your home comfort easier, smarter, and more energy efficient. Built for compatibility with most 24V residential heating and cooling systems, this thermostat gives homeowners full control of their HVAC system directly from their smartphone.
Whether you’re upgrading an older thermostat or completing a new HVAC installation, the MST07 delivers modern convenience, energy-saving features, and flexible smart automation without complicated setup.
Easy DIY Installation with Smart App Control
Getting started is simple using the MRCOOL® Connect App, which walks you through setup and registration step-by-step. The DIY-friendly installation makes it easy to replace outdated thermostats without needing professional installation in most applications.
Once connected, you can:
