Hello all,
I've just installed my Netatmo thermostat, replacing the old perry thermostat that was mount on a 503 wall box. Because my boil is too far from the wifi signal, I've installed Netatmo in the 503 wall box previously occupied by the Perry thermostat... my question is... is there a way to fix the Netatmo relè in the 503 box without diy?
thanx in advance

Hi,
We did an installation guide to help you install the Thermostat as a replacement of a thermostat made for a "scatola 503":

your guide is for install the thermostat (the part that show the temperature) in the 503 box, but i would like to install the relè in the 503. My problem is that the relè don't have a plastic plate with the recessed for the power cord (the power cord have a custom plug)

Indeed you're right, sorry for the misunderstanding!
However, the process would be almost the same if you wish to install the Relay on the scatola.
The 503 wall box has to be equiped with the adapted cover. Then, 2 holes have to be drilled to be able to mount the boiler adaptor of the Relay (or you can use the double-sided tape). Lastly, one big hole has to be drilled to allow the 4 wires to go into the wall box. The wires can be shortened, otherwise they will not fit inside the box.

i thought to do as you described, i was wonder if there was an adapter cover that will fit for this use, but if there isn't i'll try to adapt the standard 503 cover and make a square hole for the alimentation/relè contacts socket, and fixing the relè with the double-sided tape!
I really appreciate your support, thanx a lot and have a good holiday!

I had the same problem, so i've buyed an 503EC cover from Btcino, then i designed and 3D-printed an adaptor to install the netatmo base on the thermostat.

good work! but I seems you're fixing the thermostat (the part with the display) to the 503 box right? I've fixed the relè... my result is not so good because I've had cut a 503 cover... this is a couple of photos:

yeah, i've fixed the thermostat to the 503 box.
But instead of cutting the cover, why don't you make on the cover 3 hole (1 for the cables and 2 for the screw) and you dont fix the support of the relè directly on the cover?

because I don't like the space that would be created in that case... I like that the relè stay perpendicular to the cover :)

Yeah in this way is more difficult because you need to fix in some way the base of the relais, otherwise it will be not perpendicular!
Try to fix the base of the relais on the back of the 503 cover!
