[QUOTE="Roderick Smith, post: 412513, member: 27315"] Thanks again everyone, its so refreshing to be able to ask questions and get several answers to work with. I have traced the wires from both tank thermostats back to the LWC 1 wiring centre. The wires in both thermostats were Brown to Com and Black with Brown sleeve to 1, so no surprises there. However after going through the LWC 1 the wires go down cables to the Digistat, from tank 1 connections they use the Black with brown sleeve and for tank 2 they use a brown. The black with brown sleeve from the digistat (tank 2) goes to the room stat (9) on the LWC 1. The brown from Digistat for (tank 1) goes to (11) which says L Programmer Tmrw will check out where wires go to inside Digistat box, maybe electrician mixed up wires as Sharpend suggests, will keep writing the routes down. Tried again tonight with Tank 2 on oil fired and the water was scolding after 11/4 hrs, thermostat did not close until timer clicked off and valve closed. The thermostat is nearly at bottom of tank and so intend to move up to half way tmrw to see what if any differences there are, if not it must be wiring! Time will tell, once again thanks for your thoughts, they are appreciated. [/QUOTE]
