 The TA3 industrial furnace serves as a supplement to normal furnaces. This means that all goods can be produced with "cooking" recipes, even in an industrial furnace. But there are also special recipes that can only be made in an industrial furnace.
 The industrial furnace has its own menu for recipe selection. Depending on the goods in the industrial furnace inventory on the left, the output product can be selected on the right.

 ### TA3 Door Controller

 The door controller is used to control the TA3 door/gate blocks. With the door controller, the numbers of the door/gate blocks must be entered. If an `on` / `off` command is sent to the door controller, this opens/closes the door or gate.

 [ta3_doorcontroller|image]

+### TA3 Door Controller II
+
+The Door Controller II can remove and set all types of blocks. To teach in the Door Controller II, the "Record" button must be pressed. Then all blocks that should be part of the door / gate must be clicked. Then the "Done" button must be pressed. Up to 16 blocks can be selected. The removed blocks are saved in the controller's inventory. The function of the controller can be tested manually using the "Remove" or "Set" buttons. If an `on` /` off` command is sent to the Door Controller II, it removes or sets the blocks as well.

+Der Recycler ist eine Maschine, die alle Techage Rezepte rückwärts abarbeitet, also Maschinen und Blöcke wieder in die Bestandteile zerlegen kann. Die Maschine kann so ziemlich alle Techage und Hyperloop Blöcke zerlegen.

+- Stein wird zu Sand oder Kies
+- Halbleiter/Chips können nicht recycelt werden
+- Werkzeuge können nicht recycelt werden

+The recycler is a machine that processes all Techage recipes backwards, i.e. it can dismantle machines and blocks back into their components.

+The machine can disassemble pretty much any Techage and Hyperloop blocks. But not all materials can be recycled:

+- Wood turns into sticks

+- Semiconductors / chips cannot be recycled 
+- Tools cannot be recycled

+The processing power is one item every 8 s.  The block requires 16 ku of electricity for this.
