Thanks Ian.

Thanks. Was my understanding of the connections correct?

Thanks for the recommendation. I did a bit of searching and found it for £38.27 on Plumit. ( https://tinyurl.com/y377jq37 ). I guess this is a 4 wire unit in which case I presume I use N,L,3,4 connections on the wallplate and ignore 1 & 2. Can you buy the 4 pin plug to connect to the socket on...

Thanks. Again in the description it says “Enables two heating and hot water on/off periods to be set each day of the week”. Not the 3 that the original has and which according to the Worcester guy it should have with that part number. Confusing! It’s funny that all suppliers describe it in the...

Thanks but HWOS seems to be trade only.

Thanks all. Just phoned Worcester. Guess I chose a bad day. It took me nearly an hour before I spoke to anyone and to be honest I think she was the cleaner . Considering it was technical support she didn't know anything at all. She kept saying that they couldn't sell directly to the public. I...

Hi Hanks for the reply. Ideally I would like to replace the programmer with another internal one but I do have a blanking plate for it. Could you recommend an external programmer that would work?

Thanks for your reply Ian. I have just looked at that part but I haven’t found anywhere where it says that it is for the Greenstar Heatslave 18/25 boiler nor have I found any mention of 3 periods. The instruction manual definitely gives the part no 7716192033 (see photo). Do you know whether a...

Here is a photo of the programmer. As I said it has 3 periods for both hw and ch.

Hi. Can anybody help? I have an Worcester Greenstar Heatslave boiler (2008) with an internal digital programmer which is playing up. The programmer has 3 programmable periods for both CH and HW but when I have tried to find a replacement with the part no (7716192033) there only seem to be units...

Thanks oilhead

Thanks karatekid. It’s a shame that programmers are so expensive or else I would replace it to eliminate that as the potential problem.

Thanks for the replies Karatekid. Yes it is a combi boiler. I understand that the heat store tank has to get up to temperature but the boiler will not fire up at all if I turn up the room stat at any time during the day. As soon as I turn off the hot water on the programmer the boiler will fire...

Hi. I've got a problem with a Worcester Greenstar oil boiler. Both the water and the heating are on timed mode and both are activated in the morning but only the hot water fires up the boiler. To get the heating to work I have to override to switch off the water and then the heating will work...
