Abstract
A HVAC controller includes a housing and one or more heat-generating components contained within the housing. The heat-generating components cause a temperature inside the housing to exceed a temperature outside the housing. The controller includes a temperature sensor configured to measure the temperature inside the housing and a controller event detector configured to detect, for at least one of the heat-generating components, a controller event that generates heat inside the housing. The controller further includes a temperature compensation module configured to identify a steady-state temperature gain associated with the detected controller event, to calculate a temperature offset using a summation of the steady-state temperature gain, to determine the temperature of the building zone outside the housing by subtracting the temperature offset from the temperature measured inside the housing, and to store the temperature offset.
