Abstract
Abstract The present disclosure pertains to thermostats that assist users in monitoring and/or controlling their utility consumption habits and patterns. In particular, the present disclosure relates to a thermostat that includes a housing and a controller located within the housing. The controller may be adapted to implement a control algorithm that permits the controller to operate one or more components of an HVAC system. The thermostat may include a display and a receiver that is configured to receive messages from a utility. In some cases, the controller may provide, on the display, an indication of a measure of utility usage during a first time period (e.g. during a current month) and an indication of a measure of utility usage during a second time period (e.g. during the same month one year ago) that may be after the first time period.
