Wallmount controlpanel for Buderus Logamatic central heating (display unit), rugged

the OEM part is available to move the display of this central heating furnace (2005 era). 

the original is not very rugged, not suitable for placing the panel in a room with lots of people moving stuff. 

We created this replacement. 

Connection either on the panel pins inside the controller or via some contraption from the front of the controller. 

cable length of the twisted wire is not critical, since the data transfer is rather low speed. 

For the contact we improvised with some copper strips with additional solder on top. perhaps there is a better solution, but this is working for us. 

(later we added reed relais inside the controller in parallel of buttons “night” and “day” and glued relais coils on the outside to switch via an mqtt-tasmota. we did not make a new housing, but just made a quick hack… perhaps somebody motivates us in the comment to make it a new version.)
