Hi Stem,
I have these pictures of the original wiring
Pic1 1 : Is how the ESI receiver was wired
Pic 2 : This is how the boiler was wired
Where the blue wire goes into the Room Stat / Timer block, I have one wire now that goes from there to terminal 4 on the TADO extension box...
HI Stem
Thankyou for the reply! My hot water is on demand! sorry for the confusion..
That is the exact receiver I did have that was connected to my boiler. 1 & 2 on the receiver were connected to the stat / timer block on the boiler.
I have replaced this with the TADO extension. With only pin...
Morning all
Hoping someone can help me, I have wired up the extension kit as per the instructions from TADO however, it will not call the heating.
I have the grey wire connected to the terminal 4 on the tado extension and to the room stat / timer block in the boiler.
I get hot water however...
