Campini bi metal strip, anyone know the specs?

My waterco spa pump/heater needs a new over temp sensor, the markings are Campini ty60-r t210, the 210 seems to be ambient temp and the tan colour might be the actual temp it cuts off at. I can seem to find a blue one and silver one but not this one. Does anyone know where to get these?

 

Had a call from old mate at Waterco today that made these pumps. Apparently they don't sell parts separately and they wont tell me the spec. He said that they will sell me a new board for about $500 though. :x

How did you determine that that part is faulty?

The reset switch is missing, I managed to reset it and spa ran for a few minutes and it cut out. The resistor that it was attached to was not even warmer than the ambient temperature. So I was petty sus of it and wanted to try a new one before buying a new module.
