How do I replace the power cord? (Clack control valve)

Follow these steps:

1. Disconnect the power adapter from the power supply
2. Take down the valve cover (there is a pin on the outside left and right for this purpose)
3. You disconnect the power supply from the board - the 2nd connector from the bottom right (see picture).
4. In order to be able to lead the power cable out of the back of the valve head, fold down the mounting plate with the circuit board sitting on it (see picture). There are also two pegs on the top here. Important: Do not remove the circuit board itself, but rather the mounting plate on which the circuit board is located.
5. Now you can change the cable. Please note the installation through the brackets on the right.
6. You fold the mounting plate back in and reconnect the power plug to the circuit board (same plug, as under 3.).
7. Then you just have to reattach the valve cover.
8. Now you can plug the power plug back in. The system will then carry out a short self-test and will then be ready for operation again
