Hello,

I bought a new thermostat to replace my old one which has already passed away 2 times.

I have 4 cables
: 1 Black (phase), 1 yellow/green (earth), 1 red and 1 yellow.

I have 3 connections c/on/off. c is supposed to be connected to the phase, and on/off switch on the neutral.

I tested c red, one stage off yellow. heating was working, but the shot is blown as soon as I lowered the temperature.

jsuis zero peak electricity. Thank you for your help

hello

dixit you

" I tested c red, one stage off yellow. heating was working, but the shot is blown as soon as I lowered the temperature. "

off yellow !!!!!

three lines above you say that the earth is yellow green, so it is obvious that if you connect it to the off, AC breaker trips.

the son green/yellow must be connected to the earth terminal if there is one, otherwise do not connect

Bonjour

pour frmu : dmartin a écrit qu'il avait 4 fils dont un vert/jaune et un jaune. Donc il n'a, à priori, pas branché la terre sur une borne.

Cela dit, la demande n'est pas très claire :

Si vous avez un câble à 4 conducteurs, le rouge doit être la phase, le vert/jaune doit être la terre.

Sur votre thermostat, il y a-t-il d'autres indications au niveau des branchements ? Certains thermostats permettent de commander un chauffage (déclenchement si température inférieure à ...) ou une clim (déclenchement si température supérieure à ...) d'où une entrée et 2 sorties.

A+

Hello,

I have not actually connected to the earth on a terminal.. jsuis zero, but not at this point lol

I have another cable all yellow.

I say dark phase, because my tester lights up when I test the cable.

You can see the diagram on http://www.dmartin. ch/images/schema.tiff

The thermostat is just my opinion electric heating.

thank you again for your help and your time
