Hello Harrison,
thank you for your reply. Yes, I think, that it recognizes a reactor. I can set some values for thermometer and for pumps, I can measure OD, temperature and I can switch on pumps manually. I do not know whether it is possible to switch thermometer on manually, but whenever I press switch button of thermometer it crashes and the logs are the same as when it crashes after pressing start button. When I press start, I can see green label “Running”. I can see, that thermostat switch button was pressed and that T(liquid) value was set.
The logs are as follows:

I have tried several cabling connections, but it did not help in any way.
