How can I change a thermostat in an old Myson Apollo boiler?
How can I change the high thermostat in a Myson Apollo boiler. It's about 10 years old. I've bought the thermotat but can't find where to put it.
Many thanks
Remove both covers,at top right corner there is a small box shaped cover held on by one screw,remove cover by sliding forward on pipe. The high stat has YELLOW and BROWN wires on it. Easy job I have done it a few times on my 25yr old boiler.
