Can anybody help me? I still could not find solution for the temp control.
The above mentioned KST011 with 7K (±4K tolerance) switching temperature seams huge temp fluctuation for my mycology needs.
If there is another option, I'm opened for it.
I re-read this Portuguese article. That board seems similar like mine and I'm happy to follow it but I have questions.
1. What type of NTC do I need for the NTC1 connector? Which should measure the outer temp.
2. Will work if I rebuild the "Internal panel, with potentiometer" according to the provided schematic? Which connect to NTC2 (three pin connector)
Hi, I have the same problem, the board is new, the NTC controller is similar to yours but nothing is controlled, same symptoms as ypurs. Did you get any answer or resolution?
