Ideal Istor Central Heating Problem

[Glyn0704]

Hi,

I have an Ideal Istor boiler and I've just noticed that the central heating is firing independently of the central heating programmer - I'm using a remote programmer, not the one on the boiler.

I can still control the heating via the house thermostat but clearly this isn't ideal (pardon the pun).

Anyone come across this problem before?

Any help would be appreciated.

Thanks,

Glyn.
