Honeywell st9100s timer noise

[eyespy999]

Good evening

Please can anyone assist with my problem? The Honeywell timer used to function our combination boiler has started beeping periodically. Every now and then we hear two long beeps.

Their is nothing within the manual to explain what the problem is.

The central heating runs normally and has been recently serviced.

Thanks for your help.

I've just fitted one of these but have had problems in the past. The Honeywell support line is difficult to get through to but if you persist they are really helpful. Find the number on the installation sheet but you probably won't get through on that, there's an address next to it, look on the honeywell site and get the number from there and ask to be put through to tech support.

Hope it helps.
