Vaillant T3 PCBs.

[Agile]

The T3 has three piano key switches on the front and inside a mother board and two push in daughter boards.

The next generation of their boilers has only two piano key switches and a similar arrangement of PCBs inside.

Does anyone remember if the daughter PCBs are the same on both types or if they are different?

There are photos of the pcb's on hrpc parts arena but im sure the pcb are different anyway

Those photos are the motherboard and the controlo board from the T3.

I am not too sure of the exact models which used the two piano key front panel. Possible 221 and the heat only equivalents. They may have been also used on early 242s as well.
