Then plug the thermostat into an outlet, and you are ready to go. Longer Equipment Life: Conventional air conditioners and heat pumps are subject to extreme wear and tear resulting from repeated hard starts that place a lot of stress on vital internal components. [2] The compressor has the capacity to change speeds in increments as small as 1/10th of one percent, so the actual indoor temperature varies by less than one-half degree of the thermostat setting. [1] The compressor can modulate up or down to match the cooling or heating requirements of the building. The advantage of a variable-speed engine cooling fan is that the engine is better able to control its operating temperature under varying conditions. These capacity limitations result in significant wasted energy and lower levels of comfort since the system often “short cycles” by satisfying the thermostat call too quickly.
