Whoa, what an amazing job! You should send a pic to the original manufacturer, perhaps they'd enjoy seeing your conversion.

Thanks. It would be nice!

How do you solve a situation where a SSR breakdown occurs and you are hunderts km away from home?
I think some classic relay is necessary in this application to handle error conditions.
Similarly, measuring the temperature in the blast near SSR is not very accurate.

@kimot I am not handling that situation. I'm taking for granted ssr will do his job. Maybe there's some ssr safety topic I'm unaware? Suggestions for a v3.0 are welcome.
About the temperature measuring... I use two sensors. The one in the board protects electronics from temperatures beyond design (60ยฐC). It's near the ssr because the ssr's derating curve is the most limiting condition.
The control sensor is placed in the bottom of the heater. It connects to the board through a 3 pin header connector.
