Wiring Drayton Wiser thermostat

[flipflopper]

Hi there. I'm due to install a Drayton Wiser smart thermostat, replacing my current Tado

This is my current wiring for the Tado

This is the faceplate for the Wiser

The difference is the Tado uses batteries whereas the Wiser requires power to be put on to Terminal 1 by linking from Terminal L.

Could anyone kindly advise as to which colour wires go where on the Wiser?

You haven’t provided enough information to be able to answer the question, but it’s more than likely you will need to have the current control wiring altered to suit the new controls if replacing a thermostat with a combined thermostat/programmer type smart control.

Thank you for replying. Which other information would you require?
The boiler it's connecting to is a Valiant ecoTEC Pro 28, if that's any help?

I would advise you to get someone in to do it for you if you are unsure.
The Boiler you have has both 24V and 240V options.
If you get it wrong you'll be sorry!
