1. A system for detecting an amount of R-454b refrigerant in an air temperature controller using an R-454b refrigerant, the system comprising:
an R-454b control board; and
a first R-454b sensor and a second R-454b sensor electrically coupled to the R-454b control board, wherein 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;
a sensor relay electrically disposed between a bus connector input and a bus connector output such that when the sensor relay is open, power is blocked from travelling from the bus connector input to the bus connector output; and
a sensor feedback port electrically disposed between the sensor relay and the bus connector output,
wherein:
the first R-454b sensor and the second R-454b sensor are coupled in series to the R-454b control board;
the bus connector input of the first R-454b sensor is electrically and communicatively coupled to a first sensor connector of the R-454b control board by a first RS-485 connection;
the bus connector output of the first R-454b sensor is electrically and communicatively coupled to the bus connector input of the second R-454b sensor by a second RS-485 connection; and
the sensor feedback port of the second R-454b sensor is electrically coupled to a second sensor connector of the R-454b control board by a 24 volt alternating current connection.
