Abstract: A method and controller for Heating Ventilation or Air-Conditioning (HVAC), the controller having a processing unit and a storage device, the controller comprising: a mapping obtaining module for obtaining a mapping between a pair of a state of an HVAC unit and an action of the HVAC unit and between a measurement; an action determination component for determining an action to be taken by the HVAC unit in accordance with a current state of the HVAC unit; a measurement determination component for obtaining from the mapping a synthesized measurement that when transmitted to the HVAC unit is adapted to cause the HVAC unit to perform the action; and an HVAC communication module for transmitting the synthesized measurement to the HVAC unit.

Abstract: Method, system and product for assessments of an operation of an Heating Ventilation or Air-Conditioning (HVAC) unit. In module for receiving, directly or indirectly, information from at least one sensor; and a power consumption determination component for indirectly assessing power consumption of an HVAC unit from the information received from the at least one sensor. In another embodiment, the apparatus being configured to receive a set of physical measurements over time from a physical location that is affected by the HVAC unit; fitting the set of physical measurements on a predetermined curve using parametric fit, wherein the predetermined curve has an horizontal asymptote, wherein the predetermined curve has a decreasing slope over time; and comparing a target measurement of the HVAC unit with a location of the horizontal asymptote to determine whether the HVAC unit is expected to reach the target measurement.
