How to fit smart thermostats to underfloor heating

[Paul G1]

there is a test button that scrolls through various elements
The pump - you hear it kick in
Relay - the boiler starts up and ignites
Then each actuator and although the ld illuminates to show which one there is nothing else - the boiler doesn’t start up
You then scroll back to the start.

Really sorry to mither.
If the boiler connection
LS - Com (Black)
LR- NO (Brown)
I presume they are the relay?
Does it also need power?
I ask as everything is working up to the point of igniting the boiler ?
I set system to on - on my phone
Control box for that zone lights up - actuator activated and pump engages but boiler doesn’t turn on (ignite)
Thanks
Paul

Best post a photo of new wiring, might be able to see where we have gone wrong.

Yipeee !
We haven’t done anything wrong you were spot on ! There’s an actual Relay activation in the App ! When you select an area to activate you have to select relay for each area ? Not sure why but all works perfect . You’re a gent ! Apologies I don’t know your name but best wishes for the New year and thank you for your help and more importantly patience…

It’s Chris, no worries, glad you got sorted/figured it out. Best wishes to you too! (I’ve added a screenshot for future reference, that’s my “signature” and others have one too.
