Should I set up HR91 before installing

[nick323f]

Hi guys.

I have already got an Evo system set up and running but with only the controller and a thermostat.
I have bought 9 HR91s ready to cover every rad in the house. These were not part of the origin set so they are not binded to the system.
This week the plumber will fit them all for me, while he moves a couple of rads. At this stage I have no idea if he has seen this system before.

Question is: should I unbox the HR91s and set them up on the kitchen table, label them for each room then trust the plumber to fit each one in the right area?
Or is it ok to get him to fit them all. Then I’ll set it all up later?

Thanks for your help

Set them all up first then fit them. If he can't fit them in the right rooms, maybe hire another heating engineer?

Ok. I’ll start working on setting them up now then. Thanks.
