Some utilities offer time-of-use rate plans where the cost of electricity is higher during peak hours. The Time of Use optimization feature helps minimize electric HVAC usage during peak hours to increase your energy savings.
To keep you comfortable and reduce usage during peak periods, your thermostat may pre-cool or pre-heat your home. For more savings, your temperature set point will be adjusted by a few degrees. The amount of pre-cool or pre-heating and the temperature adjustment will depend on your savings preferences and the rates in your area. When you select a higher savings setting, the temperature adjustments for pre-cooling, pre-heating, and during peak periods will be higher. Pre-cooling and pre-heating will only occur if it’s cost effective.
When optimizing for Time of Use rates, you will be able to see more information when you touch the eco+ icon on your mobile app or thermostat.
