Description
The Carrier HH18HD117 is a control element known as a temperature switch used for Carrier HVAC equipment. This small but significant change is crucial in managing temperature within your system, usually, a refrigerator or defrost in the heat pump. In this case, the temperature in the control area rises above the set limit of 95°F, and the switch opens and breaks the circuit to the devices such as defrost heaters. They include the ability to control the defrost cycle or other temperature-controlled functions thus assuresing accurate thermal control. The switch helps to avoid overheating or cooling and thus the equipment runs optimally, and possibly less energy is used.
