Bosch Gas 3000W

Post by MZoltan2021 »

I have a Bosch Gas 3000W boiler.
I have no idea how to install the wireless thermostat.
Blue and Brown --> NS and LS??
Where are black and gray connected?

Try the following:

Switch off the power.

Grey to RT
Black and Brown to Ls
Blue to Ns


If the Relais‘ LED doesn‘t flash after switching the power back on, disconnect Brown and Blue again and connect them to another 230V power source.

I suppose you are talking about this model: GAZ 3000W ZW24-2 DHAE23?

Please can you help me with wiring of this boiler? What option is suitable, dry contacts directly to thermostat or relay to boiler? I attached current wired thermostat setup.

Thank you in advance!

It solely depends on how you want to position the new Netatmo Thermostat.
If your current thermostat is installed in a place where it can properly read the room‘s temperature then you can just replace it.
In your case you have to connect the brown and yellow/green wires to the terminals of the Netatmo Thermostat. Also put a terminal on the blue wire since it won‘t be used anymore.

If you want to place the Netatmo Thermostat elsewhere, go with the Relais-wiring-method as described above 😉

Position of current thermostat is perfect. My only concern is voltage. Form existing thermostat wiring looks like 220V will be directly on Netatmo. That's ok? Sorry for asking one more time and thanks a lot!
