Hi,
I'd like to be able to remotely control parameters of existing ATR121 using phone App.
Would appreciate any advice on suitable off-the-shelf modbus units that would allow this.
many thanks, David

Good morning,
The CNV580-2AD could be just the thing for you.
You can remotely control the thermoregulator connected to the CNV580 via the Pixsys Guard APP (Apple and Android). You won’t be able to configure the ATR144 remotely, just read and write the setpoints, temperature and status of the outputs.
The CNV580-2AD has the serial RS485 for communication with up to 5 devices simultaneously.
the ATR121 does not have the serial RS485, it will be necessary to go on the model ATR144-ABC-T

We are at your disposal for further information. Best regards.

Thank you. That's great news.

Is it necessary to replace the ATR121 with ATR144 and purchase CNV580?

It seems ATR144-ABC-T is out of stock and CNV580-2AD doesn't appear in online shop. Please would you advise price and availability?

Many thanks,
