Group members' plan (group members are on a killing spree)

Highly compressed automatic temperature control from group friend 'I Have a Bit Like Before', it's going crazy

Comparator can be touched inside the structure, pistons (located on both sides) use normal pistons, redstone dust is on the external heat source boiler, comparator is on the heater, the redstone line on the piston is for shutdown.

p.s. The piston head can also block the heater, really mysterious.

Remember safety production (very long)

Before formal production, be sure to claim the block explosion prevention, confirm the status and connections of each boiler. During the first test run, always monitor and run backup in advance to avoid losses. If the furnace temperature exceeds 570 degrees, it indicates an error in the redstone control layout. Please immediately remove or block the heater to avoid explosion.

P.S. Uninstall Reset

When the sticky piston structure is unloaded (entering/exiting save), it may get stuck in a closed heated state; it can be reset with a short pulse.
