LP111 programmer

[fingertight]

Hi guys, can anyone tell me if the drayton LP111 programmer is compatible with a greenstar 28i combi? I've had a woman ask. . new system installed and combi only comes on when the programmer kicks in for the heating, when the "off" time comes on programmer, power to the boier is cut off, which means no power to combi at all, meaning no hot water. Sounds like the sparky has taken the main LNE to the programmer then the boiler?

im sure the main LNE should come from spur. .to boiler THEN to programmer. . .I think its the way its been wired, but sparky has said its the wrong programmer. .which im 99.9% sure its not, expert advice required!!! thanks.

Perfectly ok for a combi. He has not took a permenant live to boiler. Switching side of clock should get its power from boiler (Ls Lr i think) and any links to live on clock backplate must be removed.

LNE from fused spur to boiler and LNE connections on clock back panel(doesnt matter if clock LNE comes directly from fused spur or from boiler connections, but boiler terminal strip is tiny)
From connection Ls on boiler to connection 1 on clock back plate out of 3 on clock(through roomstst if one fitted) back to Lr connection on boiler.

No links at all on clock backplate

Not part of the day job so think what you will

The LP 111 is not a programmer

it is a time clock, it switches on and off
