I'm pretty sure they were just plain old 10k thermistors.
IIRC, the ones that came with the system were junk. After a few years,
I replaced them (Radio Shack) and epoxied potted the new thermistors
into some old brass .357 mag cases.
One was tucked into 82 gal tank and the other was inside the insulation
on the 'down' pipe (3/4" copper).

I may have one spare somewhere in my junk, but it would be easy
to test the controller using a couple of 10k pots..
Just turn the 'panel' pot up and down and watch the relay.
