Claim Text:
1. A method of calculating a time-to-temperature estimate for a thermostat controlling an HVAC system, the method comprising: receiving a first temperature representing a current temperature of an enclosure; receiving a second temperature representing a target temperature of the enclosure; computing a first component of an estimated time representing an estimated time to transition the temperature in the enclosure from the first temperature to the second temperature by the HVAC system, wherein the first component is computed based on: computing second component of the estimated time based on a current trajectory of time and temperature values as the enclosure transitions from the first temperature to the second temperature; computing the estimated time based on the first component of the estimated time and the second component of the estimated time; and causing the estimated time to be displayed on a display device.
