Try the manual for my device, maybe it’s the same registers: https://www.airview.nl/resources/uploads/2023/02/Installatie-en-Onderhoud-Manual-WiSAN-YME-1S-2.1-14.1.pdf
Thankyou tomvoo!
I’ll try to connect next week…now i’m waiting the waveshare module.
In the meantime, do You know if It possibile to set/schedule via modbus the disinfect mode?
-M
Hi Marco! Awesome! The disinfect mode is triggerable through the modbus interface but I forgot which register it is. You also have to change the physical jumpers on the unit itself if I remember correctly to disable the automatic disinfection cycle.
Hi dear, the waveshare module it’s been delivered… And i’m ready to connect to Swan. Last doubt: is it necessary a specific connector to intercept modbus on motherboard? (Connector vs screw clamp)
Hi Giuliano, I’ve a question: the connector on motherboard is it a screwdriver connector or a specific connector?
Hey Marco, it’s just a two pin jumper connector which you should then connect to another wire to go into the waveshare
Hi all,
Sorry to come back to the thread after so long. I had numerous issues with my heat pump installation which are just about resolved. I’m wondering what kind of things you’ve been able to control with this device and what it’s allowed you to do with the heat pump in terms of automations?
Essentially, I’m looking to be able to control the flow temperature based on my local weather readings and the Met Office three-hour forecast, weather compensation was never properly set up (one of the many issues that I have encountered) and doesn’t work. As a result, I’d like to create my own set of commands to overcome this. I’d also like to be able to see the efficiency/COP of the heat pump so I can see how well (or not) it is running - it does look like people get this data.
I’ve also opened up my control panel to check the connections, can anyone confirm if this will work?
If I can’t connect directly to the panel, I’m thinking of using a waygo connector and splitting the wire to the Waveshare PoE adapter.
Thanks,
Tom
you need the H1 and H2 terminals to connect modbus. I keep repeating myself here but I highly suggest buying sven’s controller: shop | svenar
just to clarify since this thread is now mixed up between devices. Marco up here is talking about the SWAN unit, which is a hot water unit only. The unit from Sven is intended for the Clivet/Midea general heatpump.
Hi,
I appreciate that, I’m looking to buy it - but before I do I’m asking what it will allow me to do and if it is compatible with the pictured panel.
If it doesn’t do what I’m seeking there’s not a lot of point buying it. On that front, I’m finding detail a bit sparse. So, examples of what elements I can control, how well it works etc. would be appreciated.
Thanks,
Tom
Hi! honestly, I’m on the verge to give up. I have a lilygo (esp32+rs485) with a yaml connected to my ferroli omnia st 3.2, but no matter what no respond received. Where do I connect it? I have a port with letters PQEABE in the front and ABE are supposed to be modbus, but it doesn’t work. Any idea?
