they are. im at a loss. I've a third PCB board, just bought today, I'm gonna do the test again then issue a legal claim for cost to Drayton, as I know this is down to the Digistat. Many thanks

there is no L or N as it's the battery model.

yes i have a multi-meter.

John 2 final questions. 1.Would it make a difference which TA the Digistat C and On are connected too? 2. If the PCB was not earthed, could it be possible this is why the Digistat is frying the PCB board. If yes, is there any way to verify Earth wire is grounded using Multimeter or...

Yes off at mains spur. Well the Digistat is blowing it for some reason. I'm going to replace the Double pole switch tomorrow, and replace the wiring between the boiler just so I know its done right. Ive double and double checked all wiring to the board and all is correct. If the Digistat...

John Many thanks for your help. I've played stupid just to confirm that how I wired was correct, which I believed it was. Now the question is the real issue to my problem, the PCB control board blowing. 2 boards have blown since the Digistat was fitted. The boards blow under this situation...

why is there a link wire between the = & TA when the internal timer is used, but not when the Digitstat is used?

john I want to remove the internal timer as I don't need it with the Digistat also being a timer?

John The Digistat is battery model, so no L or N present. I also want to remove the internal timer clock, as Digistat+3 is room stat and time control. Would it not make sense to connect C from Digistat to =. Leave the link between = and TA(1st), and connect ON from Digistat to TA(2nd) on...

Everything is back to original now, manual time clock works. I look forward to the diagram. Any ideas why the Digistat would fry the PCB board when the power to the boiler is turned off?

Could the PCB be not earth correctly. Not sure if this is a stupid suggestion? Is it possible to test earthing if this is possible with a multimeter?

I connected the Digistat+3 to the Ta terminals, would anyone have an idea why when the power is turned off at the boiler, the Digistat seems to keep frying the PCB control board on the boiler. Would it be required to take the batteries out the Digistat when the power is turned off at the boiler...

This is another diagram for the Linea Manual, may shed some clear light on the wiring.

Yes the clock currently works. I figured simply connecting 1&2 to the existing = & TA leaving the link between = & first TA would be fine. The current timer is a 2 wire system, as this Digistat appears to be.

hi. yes I have electrical knowledge. i currently have no external stat, just an internal time clock. the time clock is currently connected to = and second TA, with a link between = and first TA.
