Zone Valve (demand ventilation) #3

Open jaros-martin opened 1 month ago

jaros-martin commented 1 month ago

Hi Peter,

by any chance, do you have any advise how to proceed in case of demand ventilation (Brink Flair 325 + Zone Valve + Air Control)? I replaced Air Control with eBUS Adapter Shield v5 and I want to read CO2 values (wires goes to Zone Valve, main unit does not recognise it, only Air Control) and control the position of Zone Valve.

Thx in advance,

Martin

That would likely be possible, but it would require you to keep the air control connected and then with ebusd record the messages sent to the zone valve and the co2 meter (I am assuming you have a ebus co2 meter), and then create a csv file for the zone valve and/or the co2 meter, so that ebusd can communicate with those.

There is a valve csv file, which might work for your valve, but you would need to set up the slave address correctly in the csv file.

Hi Peter,

Thanks for the reply. Do you have any advice for me where to connect ebus adapter, there is six port on air control but from documentation only I know is that wires from valve should be connected into ports number one and two.

The ebus adapter is connected in parallel to all other devices in the bus, so you can basically have the air control connected to the vlave, and connect the ebus adapter as well and sniff the messages from the bus. I suggest to reference the information on the official ebus adapter shield v5 for how to connect it to teh bus correctly with other devices - I think I saw the information there, though I do not recall exactly
