Abstract

Embodiments of the invention describe thermostats that are configured to precondition an enclosure and methods for performing the same. According to one embodiment, a method of preconditioning an enclosure includes providing a thermostat and computing a set of preconditioning criteria information (PCI) with said thermostat. The computed PCI is typically representative of time and ambient temperature conditions for which preconditioning should be performed. The PCI may be stored in memory and used to compare against a current time and current ambient temperature condition of the enclosure to determine whether to enter the thermostat into a preconditioning state. If a determination is made that the PCI criteria are satisfied, the thermostat may be entered into the preconditioning state to heat or cool the enclosure. One or more of these processes may be performed while a processor of the thermostat is in a relatively high power mode or relatively low power mode.
