It contains two sensors: a defrost sensor that monitors the evaporator coil to prevent ice buildup during defrost cycles, and an ambient sensor that measures surrounding air temperature for optimal system operation. These sensors work together to ensure efficient and reliable heating by preventing frozen coils and regulating temperature control. The kit is a compact and lightweight solution, measuring appro x imately 5.45 x 3.10 x 2.15 Inches and weighing around 0.13 pounds. While it doesn't affect energy efficiency ratings or tank capacity of your HVAC unit itself, it plays a crucial role in maintaining smooth operation and system efficiency.
