Mechanical clock losing time.

Hi
The mechanical clock on my boilermate 2000 has started losing time this last week, around an hour every couple of days, could it be the clock that's the problem or something more sinister. If its the clock then I might replace with a hive.

Thanks

The mechanism wears out and the motor slows down! If replacing with hive be careful if you are replacing an old mechanical thermostat as they have a neutral connection in them and getting it in the wrong place can result in damage to the pcb (I fix quite a few of the pcb's where this has happened).

Hi Murray

Thanks for your reply.
If i post a photo of the wiring on the bm2000, would you be able to point me in the right directing with regards to the wiring?
Thanks again.

There are a few videos on thee subject on Youtube, this is one https://www.youtube.com/watch?v=KpQ3uUmySXs

The manual for the Boilermate has a wiring diagram in it which will help http://www.gledhill-spares.net/documents/BM2000-Iss10.pdf

Also this is a help page I set up for installing the Nest which is similar in some respects. https://murraymartin.yolasite.com/NEST-Wiring.php

Of course if you are in any doubt I would get a competent person to have a look.

Thanks for your help.
I've managed to get it working and I'm more than happy with it.
One question, the boilermate runs from a fused spur but should the hive receiver have its own 3amp fused spur from the boilermate?
Thanks.

The receiver needs to be in the vicinity of the boiler or in this case the Gledhill unit and can be fed from the same supply (fused spur) as the Gledhill this means that when the Gledhill is isolated then the Hive will also be isolated. When fitted it becomes a part of the Gledhill installation then all items associated with the installation should be isolated in one place. If in any doubt consult a professional. Regards Murray
