Airzone reversible Klimaanlage in Modbus

[Jamsta33]

Hallo Gemeinde,

Bitte entschuldigen Sie mich im Voraus für mein Deutsch, Google Translate ist immer noch praktisch für die Kommunikation.

Ich komme hier für meine erste Nachricht, weil ich eine reversible Klimaanlage mit Airzone in Modbus integrieren möchte, die Dokumentation finden Sie im Anhang.

Bisher kann ich fast alle Daten zum System sowie zu den Zonen auslesen (beigefügter Screenshot).

Ich verstehe jedoch nicht, wie man Bestellungen schreibt und an die Maschine sendet.

Ich suche ein wenig Hilfe, um mich in die richtige Richtung zu weisen oder wenn jemand die Lösung kennt.

Hello,

I am working on the same connection method.
I have a DAIKIN heater/cooler with the AIRZONE multizone unit on top of it.
So, i have connected the Airzone Unit via modbus to Loxone.
Therefore i have used the same Airzone documentation as you have posted here in this post
Now i can read out most of the registers an put value's in some of the registers (the simple ones ).
Some examples :

• to read out the humidity of zone 1, you need to use '4 - read input register' as the command and use address 287 as the IO-address
• to set the temp for zone 1, you need to use '6-Preset single register' as the command and use addres 259 as the IO-address

so far so good, but i struggle now with the more complex part where they use bits to read or set things.
Especially in the 'system'-part where you can swith the unit between cooling or heating and other central configurations.

I see that you are already be able to read out these values, but i don't understand how you are doing that.
Which input in Loxone config are you using for "REGISTRE 00H" 'Mode de fonctio...' as described in your second screenshot ?
Is that coming from your Loxone modbus interface ? If yes what are the parameters ?

My second question is which formula you are using in the 'formula blocks' ?

Thank you already for your prompt reply. Maybe we can help eachother out ?
I see that your screenshots are in french, so for me no problem to communicate in french if this is more suitable for you
