Thanks for the advice Can you confirm that the keypad does not hold the programme info and alarm codes and all that stuff is held in the main panel ?

This is our orginal Eurosec CP8L keypad... The keys are becoming unreliable so i would like to replace it with a direct swop I have found this unit which I think may be suitable here...

Basically why doesn't the rad heat up when the outlet is fully open and the inlet is hot. The temp of the rad max is 38 degr c it should be about 50 c like the others So my question is what is causing the rad not to get hot?

I would like to bypass the immobiliser on my '97 LandRover Defender 300TDi which was fitted when the clutch isolator MeckLock was fitted. Think it may be the cause of my intermittent starting problems - turn key get no starter motor activity at all - other times its just fine. The immob came...

You are right - I am confused ! I have a Worcester 24SBi - and its not a combi ! But question still applies ! Thanks !

System : sealed/pumped, Worcester 24SBi in garage, Sunvic 3-port mid-position valve, digital room stat etc Oddity : Worcester 24 SBi altho’ being a combi boiler is installed only to provide CH (i.e., there are no HW flow / return pipes out of the back of the boiler only CH flow/return) and we...

Quick update - checked rm stat with multimeter it was fine Programmer was kaput - installed Sunvic 207xls and after some faffing all is now well. Thanks to everyone who helped us through - much appreciated

Guys My Sunvic SP100 CH/HW programmer has gone caput. Purchased Sunvic 207xls as replacement. Have successfully transferred the terminal wiring on all but one terminal The original wiring on Terminal 3 of the SP100 was a link into Live and a red-wire down to the boiler. But as you...

matt Sir you and he others on here are fantastic - really appreciate your help. Now treat me like an idiot (not difficult I know!) when you say "link out terminals 1,3,and 5" - what exactly do you mean ? Made a mad dash to B&Q tonight to ge replacement programmer in case is that's...

hi matt You are so right - its got a 13A fuse in it !! Weird that the HW program works fine - but remembering when it went bang only the CH would have be ON - so it may just have fired that circuit.

HI - thank for the rapid reply. Just noticed that turning on CH - boiler does not fire up and also valve does not move.. HOw can I physically check what you suggest ?

I have a Sunvic SP100 programmer, Tower mid-position value, Sunvic cylinder stat and Hortsmann digital room stat connected to a pumped system on a Worcester 23 SBi Last night my Tower mid-position value shorted out with a bang when the shower pump in the airing cupboard leaked everywhere. The...

HI JohnD Thanks for the advice The rad has been on wall for 6 years - I fitted it and was aware of the constrictors / diverters as you say and installed it as per manuf instuctions The other 13 tubes are all fine - but suffer allittle from a cooler middle cf. top and bottom as you say...

Thanks for your reply neds - much appreciated Its annoying that the 3 columns which are only luke warm are in the first three rows after the inlet and are before the constriction which forces water upwards and around the rad. so it affects the performance of the whole rad At first I...

I have one vertical radiator on my sealed system which is closest to the Worcester 24 SBI boiler which refuses to get 3 out of the 16 tubes heated up more than luke warm. I have drained and refilled - some black sediment came out - but to little effect. Its a huge 1.8m tall and wieghs 35 kg...

Firstly - great forum. Secondly - I've read the FAQ and other similar treads about this issue So the problem .. I have a large (1.8m tall ) 2-row 16 cylinder vertical radiator (ie, 8 front and 8 back) in the kitchen - it is the 1st rad on the system and and uses 15mm pipe into the rad...
