Claim Text:
1. A monitoring and control system for an air source heat pump apparatus having at least one controller configured to control at least one operation of the heat pump apparatus, at least one temperature sensor configured to detect the temperature in a specified area at or near the controller, and at least one operable component, the system comprising at least one control program stored on a computer readable medium, which, when executed by at least one processor in the at least one controller, causes the processor to: (a) determine the temperature at, near, and/or around the controller based at least in part on the detected temperature of the at least one temperature sensor; (b) determine whether a first condition exists, the first condition comprising a determination that the controller is powered, but the heat pump apparatus is not operating; (c) determine whether a second condition exists, the second condition comprising a determination that the controller is powered, and the heat pump apparatus is operating; (d) based at least partially on determinations (a)-(c), determine the ambient temperature at or around the heat pump apparatus using a linear function; and (e) control the heat pump apparatus to terminate operating based on the determined ambient temperature, wherein, based upon a determination of the first condition, the control program subtracts a same specified temperature unit over a time increment from the temperature of determination (a) until a stabilization temperature is reached, wherein, thereafter, a constant temperature unit is subtracted from subsequent temperatures of determination (a) to determine the ambient temperature, wherein, based upon a determination of the second condition, the control program adds a same specified temperature unit over time to the temperature of determination (a) until a stabilization temperature is reached, wherein, thereafter, a constant temperature unit is added to subsequent temperatures of determination (a) to determine the ambient temperature, wherein the heat pump apparatus is used to heat a body of water exhibiting a water temperature, and wherein the control program further causes the processor to:
