Hi, hope someone can help. I discontectd the lp111 to chanel the cables into the wall and lost the wiring diagram I drew!! I have hot water but no c/h. Wiring I have is as follows
N L 1 2 3 4

isolator SWITCH wired to N and L,
L and 1 linked,
BOILER to 1 and 3 with a block conection to the STAT
terminals 2 and 4 empty
Question is where does the 2nd wire from the STAT go??
BOILER is a Ideal and the room STAT is a Drayton digistat 1.
Thanks in advance for any help.

Thanks for the boiler info.

isolator SWITCH wired to N and L,
L and 1 linked,
BOILER to 1 and 3 with a block connection to the STAT

LP111/T1 should be connected to terminal L3 on the boiler.
LP111/T3 should go to the COM terminal on the Digistat.
ON Terminal of Digistat should go to Terminal L2 on boiler.

Boiler Terminal L1 is not used.
Remove any link between L1 and L2 on the boiler.
Leave link on LP111 in place.

Hi, thanks for that, but not sure what you mean by L and T? If you could spell it out for me, wires from stat to go X and boiler wires go to Y etc. Sorry but not an electrics person. I know should'nt be messing with stuff I don't understand but I would have been ok with my diagram! cheers.

OK. Here is the longer version.

1. Connect LP111 Terminal 1 to boiler Terminal L3.
Find which colour wire is connected to boiler Terminal L3 and connect the other end of the same colour wire to LP111 Terminal 1.

Connect LP111 Terminal 3 to Digistat COM terminal.
Find which colour wire is connected to LP111 Terminal 3 and connect the other end of the same colour wire to Digistat COM terminal

Connect Digistat ON Terminal to boiler Terminal L2.
Find which colour wire is connected to boiler Terminal L2 and connect the other end of the same colour wire to Digistat ON terminal

Boiler Terminal L1 is not used.
Remove any link between Terminal L1 and Terminal L2 on the boiler.
Leave link between LP111 Terminal L and LP111 Terminal 1 in place.

The terminals on the boiler, Digistat and LP111 are all labelled.
