I replaced the sensor on Adagio and could not find an exact match (I forget the model number, but it was indeed on a label on the sensor).
I wrote to Wema, they offered a couple of options and finally they custom built a 20 sensor unit that was reasonably priced and shipped quicky.
I was extremely pleased with how they worked with me and how the replacement part for and works.
