First thing is to remove the SD-Card from ThermIQ. It’s no longer used.

Second thing is to make sure you have the latest Thermiq-firmware. Check the current FW-version under “Settings/Main”. Current version is ThermIQ2 v4.35 0096. Upgrade if necessary

Third thing to try is to login to your Raspberry and type
sudo picocom /dev/ttyUSB0

This will start a terminal towards the ThermIQ card where you can test it with direct communication.

To get firmware verion and confirm that USB-com is working
Type

To confirm communication with the heatpump. If the later fails please check your connections with the heatpump, make sure that the ThermIQ card is in between the main-controller and any extension boards.
Also do a restart of the heatpump.
