For the water leakage sensor, we have quoted E-LD10-25 which is similar to the E-LDS10-25.
E-LDS10-25 connects to the RJ45 sensor port, but the E-2D has only two RJ45 sensor ports which are used for the two temperature sensors.
So, we will use E-LD10-25 which will connect to the dry contact terminal. Functionality of both the sensors is the same, only the connection method is different.
