Home made dryer board looking for ideas

I'm making this board it controls the heat and turn on of the dryer which code works fine

The gas valve has high limit and no fire sensor for safety and a damper that makes sure the fan is running.

So the boards only has Ac on the transformer side of the board which is plugged into the bottom
of Relay 1 to make easy replacement of the transformer. Have a look and be happy to tell me what you think I need to add.

Oh and the DS18B20 reads the temp of the dryer and cuts the gas off at 130 145 and 165.
