    MRCOOL MST07-S Smart Thermostat Remote Room Sensor

    The MRCOOL® MST07-S Remote Room Sensor is designed to improve whole-home comfort by giving your HVAC system a better understanding of temperatures and occupancy in the rooms you use most. Available from MRCOOL DIY Direct, this smart thermostat accessory helps reduce hot and cold spots by monitoring temperature, humidity, and occupancy throughout your home.

    Built specifically for the MRCOOL® MST07 Smart Thermostat, the MST07-S allows the thermostat to make smarter comfort adjustments based on real-world room conditions instead of relying on a single thermostat location.

    Eliminate Hot & Cold Spots

    Traditional thermostats only monitor one area of the home, which can often result in uneven temperatures between rooms. By adding remote room sensors, the MRCOOL MST07 thermostat can prioritize comfort in occupied spaces for more balanced heating and cooling performance.

    This creates a smarter and more responsive HVAC system that improves comfort while helping reduce unnecessary system runtime.

    Smarter Whole-Home Monitoring

    The MST07-S continuously monitors:

    • Temperature
    • Humidity
    • Occupancy

    Using this information, the MRCOOL MST07 Smart Thermostat can make more accurate comfort decisions throughout the home.

    Expandable Multi-Room Comfort Control

    The MRCOOL MST07 Smart Thermostat supports up to 10 remote room sensors, allowing homeowners to create a complete multi-room comfort monitoring system.

    This is ideal for:

    • Bedrooms
    • Living Rooms
    • Bonus Rooms
    • Home Offices
    • Sunrooms
    • Finished Basements
    • Areas with uneven temperatures

    Easy DIY Installation & Setup

    Like the thermostat itself, the MST07-S is designed for quick and simple DIY installation. Setup is completed through the MRCOOL® Connect App, making it easy to add additional room monitoring to your existing MRCOOL smart thermostat system.
