Hi, this code controls central heating and a wood pellet burner.
I would like to connect the LCD Keypad Shield 16/2 because I have to connect pc to change any settings, which is very inconvenient.
I have tried all the options to customize the LCD menu for my needs, but since my knowledge of this area is weak, I did not succeed. If I would be glad to welcome you in this room, I would be very grateful.
I need to see the current values of temp1 temp2 temp3 on the screen and allow them to be changed. Also, I will be able to change the value of the vent-pin and turn on or off the 'doz-pin' pad-pin 'uzd-pin' vent-pin.
