belling 627wh simmerstat

[monkey]

hi guys
I changed the rear left simmerstat partno. 6204034. The only is that it wont regulate the temperature it is on full power. It is a different manufacture. The old one was black and I think the manufacture is strix. Should there be a link wire?

THIS is probably what you need.

Hiya,
To work out the wiring I’d need the old Strix model number and the new regulator make and model number.

If it’s a Diamond H you fitted the most common mistake is the neutrals have been fitted to terminal 4 instead of 4A, this would allow power to the element without regulation.
The link wire from P1 to 4 (or S1 depending on the model) is required for the pilot light.
