Hello again
After fitting a new wireless thermostat to a vokera went well (with a little help from you lot) I thought I’d change the controller and thermostat etc (I dropped it and it’s not been the same since) on my Alpha eco2 plus boiler to a Tado.
Bit more complicated than the last one so here I am asking for a little help.
The Alpha has an inbuilt receiver and a wireless thermostat.
The Alpha has 4 wires, blue brown and 2 red.
I believe I’m over thinking it so if someone could just tell me which new wires go where please?!
The new blue and brown go where I’m removing the old ones? These are sharing the terminals with other wires and are not the ones immediately above the power in cable.
Existing has one red wire going to terminal 1 and the other is connected to a white connector on the circuit board. Do I swop these like for like for my new grey and black wires too?
Do I remove the link between 1 and 2?
Other answers seem to say just use the 1 and 2 terminals but why would the existing one go somewhere else?
This last photo is the underside of the wiring part with the 4 wires from existing Alpha coming in from the left
