Over Heat on Stat

Post  kojakb on Sun Mar 18, 2012 11:51 am

Hi,

Could do with some advice.!

I replaced both stats on a Pulsacoil 2000 a while ago. And the off peak one "trips" every week or so on its over heat (if thats what its called).

Prior to this, it needed the HW Sensor replacing.

Any ideas why this may be happening ?? Is there any checks I could do ??

Many Thanks for any help.

Chris

The DHW sensor not related to your problem.
As long as you fit the correct stats.
The overheat stat can be removed and the wires linked.
Gledhill has a kit; 2 stats and the link.
South coast green energies should supply it to.

Hi, cheers for your reply.

I may not have explained it properly.! The stat trips out itself, as in the black pin on the stat pops out and then needs pushing back in.

I did read somewhere that they may be wired wrong way around on the terminals (near circuit board etc).

Maybe I should check this first ? Not sure where to start with this.

Yes

I replaced the DHW sensor previously.
Then the old stat wasnt working properly. I replaced both stats as a fresh start.... and have tried them different ways around.
Both do the same thing - typically 2-4 days after use, the black pin trips out.

I havent touched the factory setting of temperature - so I am unsure what else could affect it to do this.
The client did tell me that they feel they dont get much hot water... but I believe its a few showers, washing load etc - which sounds okay to me.

Any advice would be good ?

Oh I see.! So I am assuming I have fitted the new type stats as I purchased these ones http://www.segel.co.uk/index.php?main_page=product_info&cPath=19_66_70&products_id=213

And so I need to remove the store overheat stat and bridge the two connectors ???

Is this correct ?? And if so, I assume I dont need their bridging kit - they just need joining ??
