Re: Attaching relay to motorised valves

It won't be a problem, I run mine attached to an actuator as well ;)

Re: Attaching relay to motorised valves

The Brown and Blue wires power the Netatmo Relais. It then only closes the circuit between Black and Grey. In your case Blue will be "neutral" and either Black or Brown will be the "live" wire, you'll need to figure that out by using a voltmeter. Connecting the live wire with the remaining one will ...

Re: INSTALL on Worcester Bosch Greenstar 8000 Life Combi

Brown and Blue are correct. Black and Grey don't go to the same terminal. If no other thermostat was installed before, then there must have been a bridge (wire or piece of metal) between the LR terminal and another one. You need to replace that bridge with the Black an Grey wires, meaning one goes t...

Re: INSTALL on Worcester Bosch Greenstar 8000 Life Combi

Brown wire goes to „L“ and blue wire to „N“ of the „230V Out“ terminal.
Then you remove the bridge of the „radiator symbol“ LR Terminal and replace it with the black and grey wires of the Netatmo Relais.

Re: Saunier Duval Semia Condens

If this matches your boiler, you need to add the Netatmo Relais‘ brown and blue wires to the „M5“ terminals, brown to L, blue to N.
Also connect the grey and black wires to the „M10“ terminals, labeled „39“ and „40“, which way is not important.

Re: NIBE VVM 320

Well, as far as I can tell from that manual you're able to set what function each AUX channel accomplishes. You can't really do anything wrong there with the Netatmo Thermostat, meaning you can't "break" anything. It only opens/closes the circuit between the grey and the black wire and therefore doe...

Re: NIBE VVM 320

Hm, 3-4 seems to be used for an actual temperature sensor that reports the temperature back to the boiler for it to display. The Aux-inputs are for simple ON/OFF switches (open/closed circuit) which is exactly what the Netatmo Thermostat actually does. So I'd go with the Aux-inputs. That is quiet a ...
