Seems like I got one without SSR control..

New Digital PID Temperature Control Controller Thermocouple AC 220V REX-C700 | eBay

The item description was confusing..

Trigger signal of controlled silicon: 5V/40μ S or 100mA rated current, 1A instantaneous current (self-triggering)
Output signal of solid state relay: 15±3V/30mA

I took that to mean it was SSR ready. Those SSR control pins aren't on mine.

So, I now have another digital temperature display..
I need a display for the hot water temp, and I can use this PID's relay to drive a Low temperature alarm.
(I'm going to use the smaller fish tank on left controller elsewhere).

Those two displays track very close together, but the PID's sensor is slower to change.
