I'm wanting to install weather comp on my Baxi Platinum+ system boiler (GC No: 41-470-95). This is because the house is heated using underfloor heating which is mixing down to 35c but the boiler is set to 70c to heat the unvented cylinder up to 60-65c. The idea is to select a curve more suited to the under floor heating and allow a call from the DWH to override the temp. (The existing UFH mixer would then act as protection from overheating the floor when the DWH is calling for heat)

It doesn't look like the IFOS is compatible with this boiler, I've found a "Outdoor Sensor Kit Temperature Compensation Device & Relay PCB" (part #7225851) that looks like it should be compatible, based on the install guide I found online for it, but it seems to be discontinued and no one I can find has any old stock left.

Are there any other parts out there compatible with this boiler, if not, if I can get hold of this discontinued part, is it likely to work?

Thanks!
