Patent ID: 11255562

Abstract:
A thermostat of an HVAC system receives active event parameters from a utility provider. The active event parameters include a start time, a stop time, and a predefined temperature setpoint for the active event, which is associated with a requirement to decrease energy consumption between the start time and the stop time. Following the start time, the thermostat adjusts a setpoint temperature of the HVAC system to the predefined setpoint temperature. After adjusting the setpoint temperature to the predefined setpoint temperature, a new user setting for operation of the HVAC system is received. The thermostat determines that energy consumed during operation of the HVAC system according to the new user setting is less than or equal to energy consumed during operation of the HVAC system according to the predefined setpoint temperature. Following this determination, the thermostat causes the HVAC system to operate according to the new user settings.
