Vaillant ecotec pro 28 and sensohome vrt 380f

[i860]

Hi
I just paired a sensohome_vrt_380f with my Ecotec pro 28 boiler all seems ok but now I can't adjust the temperature for the radiator flow.
If I press the radiator symbol i get only the pressure in the system and I can't adjust the temperature. If i switch off the boiler and on i can adjust the temp but the thermostat is overriding the temperature, as I set it to 60deg but when is firing it goes all the way to 75deg.
Is any way to set it to 60 and stay at 60deg?

Also, is worth buying an external temperature sensor? I am living in a flat, 2nd floor and the only place to install it will be under the window. Any savings by having one?

Thank you!

I wouldn’t think it would be beneficial. No idea why the radiator temp can’t be adjusted, unless the button is stuck?

The button is ok, it only displays the pressure in the system when the vrt380f is connected if i disconnect it i can adjust the temp for the radiators.
But once is connected i cant and the target is 75deg, i wanted a bit lower 60-65deg...

Ecotec plus 832 with SensoHome/SensoNet

Hello all, I have a Vaillant Ecotec Plus 832 connected to a Nest thermostat. I am really bored of manually adjusting the flow temperature as the Nest is not able to do this with Valiant boilers (at least not in the UK due to lack of VR33 module). Do you know if 832 is compatible with...

It would seem that from that thread that the VRT380f takes control of the boiler temperature and is changeable in the settings.

It can not be changed in the 380f settings
you can see the temp but you cant adjust it.
I think you need the external temp sensor in order to be able to adjust it.

I think it can be changed in the installer menu, have a look at page 11. Maybe @ScottishGasMan can confirm?

There is no option now in my sensohome, i think the external sensor will enable it.

The sensor arrived, i install it and all is ok now, i can set the radiator temp.
I started with 1.4 and 65 deg now is 1.2 and 60 need to see if is ok or too cold.

I have the same problem, can you tell me more about sensor? It's wired or not, and what model did you bought?

Is a wireless ot

Glow-worm Wireless Outdoor Sensor

The Glow-worm wireless outdoor sensor intelligently communicates the outside temperature to the rest of the system to provide weather compensated flow temperatures for maximum efficiency. The sensor is small and discreet, and no wiring is required between the unit and the rest of the system.

Ok, can you describe connection, because my vaillant support told me that i can use vrc 693 only (vired model) now I'm confused
