The program reads temperatures. That's a clear reason to go buy a beer 
Thank you for the information. If you need anything else, write it here, please.
Have you solved the switching of outputs according to temperatures with the second board? What is the current load capacity of those relays, what is the power consumption of the heaters, will you power it directly from the second board, or will you use contactors or other auxiliary relays for higher current? Have you solved this yet?
