Abstract
The present invention provides a system for detecting an amount of R-454b refrigerant in an air temperature controller using an R-454b refrigerant, and a method of installing a configuration of R-454b sensors in the air temperature controller using an R-454b refrigerant. The system includes an R-454b control board, a first R-454b sensor, and a second R-454b sensor. The first R-454b sensor and the second R-454b sensor are coupled in series and electrically coupled to the R-454b control board. Each of the first R-454b sensor and the second R-454b sensor include sensing components configured to detect the amount of R-454b refrigerant.
