Hi, just checking wiring going from Honey Well T6R to Drayton wiser back plate.

N L Black Grey on current honey well, should go to N L 3(black) 4 (Grey) and then link L to 1 and 2 ?

I assume you have the 2 Channel Wiser like below. If not don't proceed and provide details of what you do have.


In which case. N & L are a straightforward swap over from Honeywell to Wiser.

Grey wire now in B is Heating on goes to Wiser (4)
Black wire now in E is Hot Water on goes to Wiser (3)

No connections to be made to the 'off' terminals (1) or (2) and no external links required either.
HI, appologies- yes its 2ch as below. Brilliant - many thanks, especially confirming no links -much appreciated.
What’s the reason for the change to Wiser? If you’ve still got the T6R are you interested in selling it?
