Smart thermostats for multi-story heating systems work by using multiple sensors to monitor the temperature on each floor of the building. These sensors communicate with the smart thermostat to provide accurate temperature readings for each zone. The smart thermostat then uses this information to adjust the heating system to maintain the desired temperature in each zone, optimizing comfort and energy efficiency. Additionally, some smart thermostats can also take into account factors such as occupancy and weather forecasts to further optimize the heating system's performance. **
