Intergas HRE 24/28 & Nest 3

[BSF75]

Hi

I have an Intergas HRE 24/28 & was looking to purchase a Nest 3 & I was looking for some advice please

From the reading I have done - I need to ensure there is power to L & N in the Heat Link & wire OT1 & OT2 in the Heat Link to X4 11 & 12 in the boiler - removing any other connections in X4 in the boiler.

I then set the nest to open therm in the settings

This seems fairly simple & I feel like I am missing something

Can anyone advise

Thanks for any help you can give

Many Thanks

Brett

It depends how old the boiler is. You don't always remove all other connections on X4 - if it's an ERP model you could disconnect the power to the pump!!

Is the pump round or oblong?

Hi

thanks for the quick replies

the pump is round

In the X4 I have a link between 4 & 5 & connections to 6 & 7 for the old thermostat

thanks again

Perfect!!

Leave the link between 4/5 on X4 and remove the old stat wires then proceed as you said in your first post
