Worcester MT10 timer faulty. Rec replacement

[houstonwehaveaproblem]

The timer has packed up on our Worcester boiler.

Looking to replace. Any recommendations for a replacement. Looks like the MT10 is still available but I'm looking to replace the mechanical wall thermostat with a programmable type

Cheers

Yes, go with a programmable type. Is it the timer that’s broken or the on/off switch? No recommended replacements I know of only the same type. Not a diy job, as removing the cover requires a critical safety check afterwards as it forms part of the combustion circuit.

Thanks.

It's working ok if I leave it set to on and just use the wall thermostat so I'm guessing it's the timer. Just trying to find a good programmer to replace it

Plenty available. Depends on budget and what you want to achieve

After something that i can program
for daily heating times.
Boiler is a combi

If there's an existing stat, what is it, could.you show us the wiring behind it?
A modern smart stat, or receiver could replace the existing stat and include the functionality of the time switch, without having to remove the boiler cover.
Just leave the MT10 set to permanently on.

I haven't took it apart yet but it's a conventional Drayton thermostat

The wiring behind it would dictate our recommendations, but definitely doable!
(Usual disclaimer: isolate power safely before removing any covers!)

Thanks. I will take a look tomorrow and report back

Probably going to be a 2 or 3 wire type. If 2 wire, then battery operated would likely be the way to go. If 3 wire, you might be able to go for a mains powered.

I have seen those clocks work back to front when they have played up in the past pulling out or pushing in the pins has the opposite operation than they are meant to have

I will check that
