Re: Vaillant boiler won't turn on

Hm, wiring seems correct and all. Just to clarify: You say both new Netatmo Thermostats work correctly when you connect them on the newest boiler. The other two older boilers also turn on when you put a bridge between 3/4 and they turn off if you remove that bridge. Correct? If so this is very weird...

Re: How many Smart Radiator Valves?

If you want to control each and every room individually, you will need to install valves on all radiators. If you leave 1 and 2 without, they will always heat, even when only radiator 6 would request heat. If you put valves on all radiators, assign valves and thermostat to the correct rooms and run ...

Re: Netatmo sur chaudière edilkamin Ottawa

First of all, maybe somebody in the French section of the forum has the same setup. https://forum.netatmo.com/viewforum.php?f=14 I googled your boiler and read the instructions manual, but I couldn't find any reference about connecting a 3rd party thermostat directly. Also the circuit board (assumin...

Re: How to connect Netatmo S+arck ?

Make the following test: Switch on your boiler and then turn off the power. Remote the bridge-cable from the "opentherm" terminals and switch the power back on. If your boiler won't start again, connect the Netatmo Relais grey and black wires to those terminals (+ brown and blue to a power supply) a...

Re: Vaillant boiler won't turn on

Well, if it works with the bridge-cable then it has to work with the Netatmo Thermostat as well. So a defective Thermostat seems likely.

Re: Vaillant boiler won't turn on

We always have to consider that the Netatmo Thermostat can be defective. To do a simple test, switch off the power and put the original bridge-cable back between 3-4. If your boiler also doesn't turn on after you switch the power back on, you have to change the settings on the boiler. Meaning you ha...

Re: Control boiler by valve temperatures

You‘ll have to try that and see how reliable it works.

Re: Saunier Duval ISOFAST F 35 E

Splitting the power supply wires with terminals would be an option.
You say there are no screws but at least the main supply cable has to be detachable somehow.
Or if it was a preinstalled cable, it's connected to a wall outlet.

Re: Control boiler by valve temperatures

You'll will need to create 2 different "homes" in your Netatmo account, one with only the thermostat for floor heating and one with the thermostat for the valves and the valves themselves. There will be a dropdown menu on the top in the app to switch between them. Heating zone 1 (floor heating) will...

Re: Control boiler by valve temperatures

@AndyML I think that the relay of the valves and the one of the thermostat is exactly the same, and you may need just another relay. Not it‘s not. The Relais that comes with the Thermostat can control a boiler, the one that comes with the Valve-starter-pack cannot. That‘s why no boiler cable is inc...
