It's from about 2003, and I think model TSTATCCPRH01-B
I broke it, well a little, though it still seems to run AC OK - while displaying E5.
I bent H1 on the back of the card and broke off one of the leads.
If I could buy the three-terminal device with leads, I could solder it onto the old leads.
What is H1, and is there any way to buy a replacement?
