Location. Temperate grasslands are located north of the Tropic of Cancer (23.5 degrees North) and south of the Tropic of Capricorn (23.5 degrees South).The major temperate grasslands include the veldts of Africa, the pampas of South America, the steppes of Eurasia, and the plains of North America.limate. Temperate grasslands have hot summers and cold winters. Summer temperatures can be well over 100 degrees Fahrenheit, while winter temperatures can be as low as -40 degrees Fahrenheit. They typically have between 10 and 35 inches of precipitation a year, much of it occurring in the late spring and early summer.
In summary, certain conditions can force a heat pump into a defrost cycle (or cooling cycle) where the fan in the outdoor coil is stopped, the indoor fan is stopped or electric heat is turned on, the frost melts and is removed from the outdoor coils.
Where to start: troubleshooting a heat pump If your heat is not working, start by checking the thermostat. Is it turned on and set to heat? Try setting the temperature 2 to 4 degrees above room temp. (When troubleshooting heat pumps in cooling mode, follow this same process but set the temperature below room temp instead of above.) Switch the fan on. If the fan doesn't start , check the fuses and breakers. Replace the fuse or flip the circuit breaker to the closed position and determine the cause of the overload.
