Are you using the latest code with HA autodiscovery? Everything works ok for me and no such warnings. Are you using some other climate devices over MQTT? Below is the full config for CA350 climate and the options that are mentioned in your warning messages are not there:
How have you configured it in HA? Are you relying on the HA auto discovery or you have your code in configuration.yaml? If the latter you have to check it and adapt to the MQTT Climate integration standards but I would highly recommend to get the latest code from github and rely on the auto discovery which works very well.
Probably yes, but this solution does not use this config parameter. Neither it uses the away mode which has been deprecated as well. Unless it is done somehow implicitly that I’m not aware off. Anyway the up to date code which is using the HA auto discovery does not generate those warning messages.
Update: I’ve realized that I’ve had log level set to error. Switched that to warning and I can see those errors as well now. I’ll investigate it but I have a feeling that they’ve put this warning for anyone using MQTT Climate devices regardless if the use those options or not.
What is the state of binary_sensor.ca350_filter_status sensor? Based on my experience it only resets if it is already in ON state. And also according to the manual it resets if you press the button and power off - power back on the ventilation unit. I guess it somehow reflects the situation that you perform the maintenance / replace filters with the unit powered off.
I would suggest that you connect to RPi with SSH only, change the debug parameter to True in config.ini and run the script again. It will be quite talkative so you should see if there is any specific place where it gets stuck.
I would also check if the serial port name has not changed, although it would simply throw an error message rather than freezing entire RPi.
Hi adorobis&Tim! Great work and summary, thank you!
I have a problem. I did everything as described, but mqtt (rasbian) doesn’t want to connect to my HA broker. My other devices connect to my HA brokerage without any problems.

Define port without quotation marks. E.g. MQTTPort=1883 as it should be a number not string. Similarly MQTTKeepAlive. Btw, are you using the latest version of the script? The config should be in a separate file config.ini
