Remeha 39c running pump after *cold* water demand?

[Andy.T]

Hi there,

I've just noticed that my Remeha 39c is firing up for a couple of seconds after I turn a cold tap off (only when it's been running full, strangely)? It's not a big prob but I'm pretty sure it didnt used to do it.

The operating modes on the display when it does this shows as...

1 (Pre-purge stage)
2 (Ignition stage)
1 (Pre-purge stage)
7 (Pump run on after CH or DHW is satisfied)

...is this normal? Is it just linked to the cold weather at the moment?

Cheers,

Andy

Do a forum search for "dead leg" and before you know it you'll be an expert on the subject

Ahh that's great thanks for that.

We are halfway through a new bathroom installation at the moment so maybe it's one of the unused pipes for that or something.

Cheers again,

Andy
