Types of thermostat setbacks

Time-based setbacks

Time-based setbacks involve programming the thermostat to automatically adjust the temperature settings at specific times throughout the day. For example, you can set the thermostat to increase the temperature during work hours and decrease it during the night when everyone is asleep. Time-based setbacks are a reliable and straightforward way to achieve energy savings.

Occupancy-based setbacks

Occupancy-based setbacks rely on sensors or manual inputs to detect when a space is unoccupied. By using occupancy sensors or manually signaling the thermostat, it can adjust the temperature settings accordingly. This allows setbacks to be implemented even during unexpected periods of absence, ensuring energy savings when you forget to manually adjust the thermostat.

Weather-based setbacks

Weather-based setbacks utilize real-time weather data to automatically adjust the temperature settings of your thermostat. By taking into account external conditions, such as outdoor temperature and humidity levels, the thermostat can optimize energy usage. For example, during milder weather, the temperature can be set slightly higher or lower to reduce the workload on the heating or cooling systems.

Choosing the right setback strategy
