Donde conectar un sensor externo de plomeria

The provided context does not mention an external plumbing sensor or its connection point for the Mitsubishi PLA-A12BA. However, it lists various connectors and thermistors related to refrigerant piping and temperature sensing. If an external plumbing sensor is to be connected, it would likely be through one of the thermistor connectors (TH3, TH4, TH6, TH7, TH8) or an option connector such as CN51 or CNDM. Specific details would require referring to the installation manual.
