Combi (Ideal Logic 24) is burning away when remote thermostat is set as "off"...

[AL_n]

Hi all,

I have an "Ideal Logic Combi 24", which was installed two years ago by British Gas engineers.

When I switch it off via the remote thermostat/controller, it still keeps burning for a very long time. I have to switch it off at the mains outlet to stop it from firing up when it shouldn't be firing up. Can anyone suggest what is causing this? Is it the frost protection feature perhaps? Can I switch frost-protection off (permanently) somehow? The user manual doesn't say how.

If it's the frost protection that is causing the thing to stay buning when it's not needed, something is wrong, because it happens even when the outside temerature is way obove freezing point (17 degrees, even).

Thanks for any help...

Are you sure it's actually burning or just running the pump to disperse the heat build-up in the boiler?

is the frost protection stat set correctly?

Some boilers fire up to preheat the DHW this can usually be switched off by setting Eco mode.

When a fan assisted boiler turns off, the fan continues to run for a while (with no flame) to ensure combustion gases are cleared from it. And before ignition to enesure there is no gas leaked into the boiler due to a faulty valve.

British Gass Engineers, an Oxymoron if I ever heard one! Brian

Thanks for the reply. I guess you may be right; it may just be the pump I'm hearing. It seems to go on for a very long time after the thermostat controller has been switched to off.

I've no idea. I'd like to know how to access it and check that it's set correctly, but there's nothing about it in the handbook.
