A crankcase heating control system for a heat pump system includes a data receiving module and a power control module. The data receiving module receives data indicative of a temperature of a compressor of the heat pump system, data indicative of an ambient temperature, and data indicative of a current date and a current time. The power control module selectively applies power to a heater of a crankcase of the compressor and selectively disables the heater based on the temperature of the compressor, the ambient temperature, the current date, and the current time.

1. A crankcase heating control system for a heat pump system, the crankcase heating control system comprising: a data receiving module that receives data indicative of a temperature of a compressor of the heat pump system, data indicative of an ambient temperature, and data indicative of a current date and a current time;a power control module that selectively applies power to a heater of a crankcase of the compressor and that selectively disables the heater based on the temperature of the compressor, the ambient temperature, the current date, and the current time; anda difference module that sets a temperature difference equal to the temperature of the compressor minus the ambient temperature,wherein the power control module disables the heater of the crankcase when the temperature difference is greater than a predetermined temperature. 2. The crankcase heating control system of claim 1 wherein the power control module applies power to the heater of the crankcase when the temperature difference is less than a second predetermined temperature that is less than the predetermined temperature. 3. A crankcase heating control method for a heat pump system, the crankcase heating control method comprising: receiving data indicative of a temperature of a compressor of the heat pump system;receiving data indicative of an ambient temperature;receiving data indicative of a current date and a current time;selectively applying power to a heater of a crankcase of the compressor;selectively disabling the heater based on the temperature of the compressor, the ambient temperature, the current date, and the current time;setting a temperature difference equal to the temperature of the compressor minus the ambient temperature; anddisabling the heater of the crankcase when the temperature difference is greater than a predetermined temperature. 4. The crankcase heating control method of claim 3 further comprising applying power to the heater of the crankcase when the temperature difference is less than a second predetermined temperature that is less than the predetermined temperature.
