So once again you've backtracked on the lies you wrote earlier.
It's perfectly normal and legal to buy boilers in this country which cannot have any compensating controls fitted.
You were challenged before about your lies referring to "all boilers" and on that occasion pulled back to one independent manufacturer of controls and what they happen to sell in this country.
Why do you persist in constantly and deliberately misleading people?
This is far from the only issue.
We have to assume it's because it fits with what you choose to sell.
