MRCOOL® MST07 Smart Thermostat + MST07-S Room Sensor Bundle (White) - 24V (Ducted System Only)

Smarter HVAC Control with Whole-Home Comfort Monitoring

The MRCOOL® Smart Thermostat + Room Sensor Bundle combines the powerful MST07 Smart Thermostat with the MST07-S Remote Room Sensor to create a more intelligent, responsive, and energy-efficient HVAC experience.

Instead of relying on a single hallway thermostat reading, this bundle allows your system to monitor temperature, humidity, and occupancy in the rooms that matter most—helping eliminate uncomfortable hot and cold spots throughout the home.

Whether you’re upgrading an existing HVAC system or completing a new installation, this package delivers modern smart-home convenience with advanced energy-saving automation.

Complete Smart Thermostat Control from Anywhere

Using the MRCOOL® Connect App, homeowners can:

• Adjust temperatures remotely
• Create custom schedules
• Set temporary or permanent holds
• Track energy usage
• Monitor room conditions
• Control comfort from anywhere

The thermostat also works with:

• Amazon Alexa
• Google Assistant
• iPhone & Android devices

Why Add a Room Sensor?

Traditional thermostats only monitor the temperature where the thermostat itself is mounted—which often leads to uneven comfort across the home.

The included MST07-S Remote Room Sensor helps solve that problem by monitoring:

• Occupancy
• Temperature
• Humidity

This allows the HVAC system to respond more accurately to real-world conditions in bedrooms, living rooms, offices, and other commonly used areas.

Designed for Better Comfort & Lower Energy Bills

Smart automation features help reduce unnecessary HVAC runtime while maintaining more stable indoor temperatures.

Features include:

• 7-day customizable scheduling
• Smart preheating & precooling
• Adjustable temperature swing settings
• Fan circulation mode
• Daily, weekly, and monthly energy tracking
• Maintenance reminders

The result is a home that feels more comfortable while using less energy.

Easy DIY-Friendly Installation

Both the thermostat and room sensor are designed for quick setup using the MRCOOL® Connect App. Installation is simple and homeowner-friendly for most 24V HVAC systems.
