Systems and methods for air temperature control using a target time based control plan

Abstract

A system and method for controlling the air temperature of a building using a control plan based on a target time. The system includes a controller which may be connected to a number of indoor and outdoor heating ventilation and air-conditioning units. The system may include a thermostat. The system may also operate without a thermostat. The method includes determining a control plan to reach a desired temperature in a target time. The method also includes updating the plan by comparing the actual time to reach the desired temperature with the target time.

What is claimed is: 
     
         1 . A method for controlling air temperature in a building, comprising:
 wirelessly receiving, via a controller, as user input a target air temperature and a target time; and   operating, via the controller, one or more equipment of a heating ventilation and air-conditioning (HVAC) system to achieve the target air temperature in the target time, wherein the operating comprises:
 operating the one or more equipment of the HVAC system according to an initial control plan; 
 determining an actual time taken for achieving the target air temperature; 
 determining a modified control plan when the actual time is not same as the target time; and 
 operating the one or more equipment of the HVAC system according to the modified control plan.
