Wanted: Buderus FM244 and FM241 (Solar and Mixing) R2107 modules

vilord Member Posts: 48
I'm in the process of gathering all the parts to switch my G115WS boiler to logamatic R2107 control.
We have solar hot water with backup boiler indirect heating, so I need an FM244 card (63038596), which is no longer sold.
Does anyone have an old one sitting around in their truck or shop?

We also have dual temperature heating, so I need an FM241 mixing card (5016598)... this one is at least still available, but to make back the new price in efficiency savings will take quite a while, so any bit of savings we can do would be nice.

Thanks all!
