Could someone please send it to me (although also from another Fairland model) ?

Thanks.
Hi, I also have IPHCR26 with this connector. Are you sure with wirings? Do you know name/type of this connector to get male side?

I've ordered these no name ones, they seem to fit, but the connector on the heat pump is somewhat deformed so the screw cap doesn't thread on that well. electrically it seems to connect fine though.

And like everyone, I too, would like to receive the registers

I'd also be interested in the modbus documentation. Much appreciated, Thanks in advance.

UPDATE: Can't send private messages yet. That was quick, thank you!

Very interesting post.

I have a different brand of heat pump, but since I read a lot of heat pumps are a rebranding of Fairland, I hope I can also get it to work.

Can you please share the modbus registers with me as well?

Thanks in advance!

Update: thanks a lot

Hi @enboer many thanks for providing the inspiration and sharing your discovery of the modbus port and the modbus docs.

I have shared my build over in the homeassistant forums. The forum software won't let me post the link though.

Hello, I have two heat pumps and I would like to change the address of the device, can you advise me how to do it.
Thank you

Hi, would someone be willing to provide me with a table of modbus codes for the fairland heat pump?

Thank you in advance !!!

Hey,

Like a lot of you before me: can someone please send me the Modbus register.

Thank you

Modbus registers file is now part of the Github repository

Hello,

I have all the information about the modbus registers, but how can I modify the slave address? I cannot find any info about this...
In my network, the slave ID 1 (the default address) is already used by another device, so I have to change the address of my heat pump.

Posted: **Tuesday 26 March 2024 10:18**

I think you need to add the parameter slave=2 (the slave number) to the register call.

Could anyone share the register file?
