Application
This sensor is engineered specifically for use in Marvair commercial packaged terminal air conditioners (PTACs), vertical packaged units, and other Marvair climate control systems. It communicates temperature data to the control board, enabling the system to accurately modulate heating and cooling output for consistent comfort and energy efficiency.
Why Choose the Marvair 70369-YL
Using a genuine Marvair OEM sensor ensures compatibility and reliable operation. The NTC thermistor technology provides a predictable resistance-to-temperature relationship, allowing the control system to make precise adjustments. The yellow color code eliminates guesswork during multi-sensor installations, reducing service time and the risk of wiring errors.
