Ａｎｙｏｎｅ ｆａｍｉｌａｒ ｗｉｔｈ Ｗｏｒｃｅｓｔｅｒ ４&#

[bluesky]

Dear all,

Trying to install a Worcester 440CDI floor standing boiler. Never installed this one before. Read the manual carefully before start. The wiring looks similar with other Worcesters. However when i tried to commission it only hot water is working. If i turned on the programmer the central heating looks not working at all. Check the voltage in Lr, it is 230v. Should be ok.

I read the manual again and again, tried again and again. But no luck. Have i missed anything? Cannot phone Worcester because today is Saturday. The tenants complained bloody cold.

Any help will be appreciated indeed.

Thanks in advance.

What timer have you fitted? And what have you wired to where? What links have you removed etc?

Hi APPlumbing,

Thanks for your quick reply. Yes it has a small storage. I thought it was only for hot water. Does it also works for central heating as well? Ｉfound it is bit different with other boilers.

The programmer is Drayton LP112 (Mk4) Programmer. Still the old one which still working. I　ｔｅｓｔｅｄ　ｔｈｅ　ｖｏｌｔａｇｅｓ　ｓｅｎｔ　ｔｏ　ｂｏｉｌｅｒ　Ｌｒ，　ｌｏｏｋｓ　ｉｔ　ｉｓ　２３０ｖｏｌｔｓ．

Hi gas man, i have not connected room thermostat, i only use the Drayton programmer. Ls and Ns connect to programmer L, N, then connect Lr to programmer heating on, is this correct?

If you have 240v at lr heating should be on. If the heating stat on the boiler is turned up amd you have 240v at lr the booler has a fault. Could try it on chimney sweep, hold bottom left button fpr 10 seconds, it should fire on full burner on heating.

Is the boiler doing anything at all qith 240 at lr?

Did you take a link out when you were wiring it?

Cannot remember exactly where the link from. It dropped when i tried to wire ls and lr. So think that was between them

If there's 240 at lr on the st10. Either the boilers in summer mode, or its fubard.
