Trying to fit a wiser kit 1 to a baxi duotec

[V60lee]

Evening everyone , I’m in need of some help.

My baxi duotec 28 combi has one of those mechanical timer / programmer things with all the little switches around the outside and I’m wanting to fit a wiser thermostat kit 1.

Can anyone tell me how to wire it ?
The old timer has 4 wires coming out of it ……

Many thanks

I assume one of these the diagram is likely somewhere on the programmer.

This was on mine, so four wires 2, L, N and earth. I still have the old timer so I could ring out the contracts if required, but

looking at wiser N to N, and L to L with a like L to 1, and 2 to 2. But this does not take account of any existing thermostat.

The main thing is to ensure right version pictures are good, there are three Wiser hubs

and loads of other timers with fingers, so best it post pictures.

Is this an internal clock or external like @ericmark suggests?

I’m fitting a WT714R one channel.
I have a honeywell DT 90 screwed to the wall that I want off.
The timer is like the baxi optional programmer , round thing that has loads of little switches on the outside and has a little ‘ off , timer , on switch

Ok, I would leave the time clock in unless you want it out and just leave it set to permanently on. The wires for the DT90 should come from the boilers PCB. The Wiser can be piggybacked from the boiler LNE and then just the 2 switch wires to common (1) and NO (3) - no need to provide a link as the boiler sends mains out with the wiser sending a switch live return. Make sure you remove the 2 Honeywell wires and then place them in a terminal block and the same at the other end or just leave the thermostat connected as it won't do anything.

Hope this makes sense?

Any chance of a drawing diagram haha

The time clock as progressed through the years

and each one is slightly different, and wires carry electric regardless of colour, so one starts with looking at how connected to what you have. These

or a variation of them were used for years, some even adjusted for the season, some did days of the week, and the whole clock plugged into the case, it simply pulls out.

As google for DT90 got this

which is not what you are describing. It seems some were battery powered, so there may be no mains to power the Wiser hub, my wiser hub is in the flat under the main house, close to the boiler, did look like this and it was hard enough to re-wire being in the house with all my meters, however, the old thermostat was also wireless I never did find the thermostat, but with wireless easy enough to wire close to the boiler. And place the sensing bit, quite remote from it, which is the whole reason why I added Wiser, the Nest thermostat went where the wires went, in my case the hall, where the Wiser sensing bit went in the living room.

I hope you can see from my post how pictures help, and can do the same.

Sorry, not from me. No good at that.
