Which Drayton wiser backplate do you have?

So from existing to Drayton Wiser:

L to L
N to N
NO1 to CH1 on
NO2 to CH2 on

The common isn’t required at the Wiser, but may need to go to one of the L’s, just depends if it’s a link wire or not.

 

[Simon88]

Yeah the common is a link wire, Ill give this a go shortly - thanks

 

[Simon88]

I've tried that and it won't call the boiler to heat, if I turn the other danfuss unit on it calls the boiler then the wiser will work, any ideas?

 

[Deleted member 267285]

What other Danfoss unit? A thermostat? If so, this must be set to maximum or wires linked together.

 

[Simon88]

I have a second danfuss in the bedroom whats the best way to sort set it to link the wires?

Just some connector blocks, wago’s or if you are worried about decoration, put the 2 wires in the same terminal at the stat.

 

[Simon88]

So take the front plate off and then move all the live wires to L, sorry if this seems like dumb questions.

 

[Simon88]

Or can I just put a link wire between the channel and live?

 

[Deleted member 267285]

Yes, or to switch, or do what you’ve said and place a link. Once this is done, the Wiser will take over the temperature.

 

[Simon88]

Perfect ill try that tomorrow and report back thanks for all your help
