Thank you for your assistance. Off to get a replacement timer. Really appreciate your help.

Oh it appears the audible beep is a good think and not a warning, sorry a total novice at this! Seems to me it is the timer!

Just run the continuity test and the instructions say there is an audible warning if below 50 ohms. The warning goes of and the reading is 003. Unfortunately I cannot interpret what this means. Is it just the wire that has broken and would it be worth replacing this before I replace the timer...

Thank you. I have already checked all of the connections in the timer, thermostat and all the electrical connections and all are tight. Not too sure how to do a continuity check - will look at the multimeter instructions and let you know.

Sorry It has been some time since last post - busy week! To recap the system had been working fine for 2 years without any problems. Since the issue I have replaced the head on the Honeywell Valve (CH) with a brand new one and this has not changed the issue so it would seem doubtful that the...

Just going to get a multimeter now but will not have much time to check stuff today as I have got my twins birthday parry to attend. Never used a MM before so should be a good learning curve. Thanks

Forget my last post, problem is as originally stated. With the HW off and the CH on I have latched the Honeywell valve open manually and the boiler does not fire. However, if I then move the HW valve open the boiler fires immediately, even though the HW is off. If the HW valve is then...

OK I will try that. Seems as if the CH may be on all the time since I replaced the valve head this morning! Think I will let it cool down and start testing again this evening including the above suggestion. Will let you know how I get on.

No I do not have a multimeter. We had not changed anything when the system stopped working

Hi. We have a gas boiler on an unvented central heating system. Recently the CH stopped coming on when on the timer, unless the HW was set to come on at the same time. If the CH is set to come on it does not, but does once the HW timer comes on 2 hours later and then all is OK. Once running...
