Hi guys,
I've tried to upgrade my current CH programmer from a Randall 4033 to a Honeywell T6R-HW.
I have an Ideal Classic HE15 boiler, hot water tank upstairs in the spare bedroom and header tanks in the loft (hopefully that narrows down the type of CH system I have).
The problem i have is how i switch the wiring from the 4033 to the new T6R-HW.
Below is a picture of my current wiring setup and my interpretation of how this should be wired into the smart thermo.
Am i right that;
1 - no longer required
2 - A
3 - not used
4 - E
5 - not used
6 - the red and green now go into the first L feed
7 - N
8 - Earth again (block 1 on the smart thermo)
Appreciate any input
