Intergas boiler combined with OpenTherm and Weather Compensation

I have an Intergas Eco RF 36 with a T4R and weather compensation.

I'm looking for my installer to change the current wiring over to OT.

Having read a lot today, I'm confused as there lots of conflicting opinions as to whether WC and OT can work together without problems, but not what the issues would be?

Thanks in advance.

 

No, they don't work together, you have to pick one or the other. Have a feeling the T4R can take a weather sensor, which would then give you both together, but I've never actually tried that. Personally I'd just go for the OT and drop the WC
