I have not succed to configurated my SESTOS digital PID with an temperature sensor probe working between -40°C to + 120°C. I put CtrL to 3 ( PID ) SN to 20 ( cu50 matching my sensor ) and Op1 to 2 ( Al1 actived ) All the others parameneter I left the factory setting.
When I escape from the setting the red display show a wrong temperature ( arroung 50° when we have 20°C ambient. I try with a PT100 sensor normally SN set at 21; it is also not working ( AT green display and RED display are blinking. Please, could you give me a good setting for SESTOS digital PID for my application: I used it for an water boiler to regulated the temperature between 10° to 70°C. thank you for your help.
