Product Description 

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 The DIY-friendly installation makes it easy to replace outdated thermostats without needing professional installation in most applications.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:

• Adjust temperature remotely
• Create custom schedules
• Set temporary or permanent holds
• Monitor system performance
• Track energy usage

Built for Comfort in Every Room

Unlike basic thermostats that only monitor one location, the MST07 supports up to 10 optional remote room sensors for complete multi-room comfort control.

This allows your HVAC system to prioritize temperatures in the rooms that matter most—helping eliminate hot and cold spots throughout the home.

The MST07 includes intelligent automation features designed to improve comfort while reducing unnecessary runtime.

Features include:

• 7-day customizable schedules
• Smart preheating and precooling
• Adjustable temperature swing settings
• Fan circulation mode for fresh air movement
• Daily, weekly, and monthly energy tracking

These features help improve efficiency while maintaining a more stable indoor environment.

Voice Control & Smart Home Compatibility

The MRCOOL® MST07 works seamlessly with:

• Amazon Alexa
• Google Assistant
• iPhone & Android devices

Control your HVAC system using voice commands or the mobile app from anywhere.

Designed for Long-Term Reliability
