Incompatible fan speeds

[gustonator]

Hi, thanks for the integration. I have 1 issue with the fan speed. I’m usint the Atrea RA5 unit, and I don’t have 15%, 20%…100% speeds there, but this:

for circulation: Off, Min-Circ, Norm-Circ, max-Circ

for ventilation: Off, Min-vent,Norm-vent, Max-vent

If I use the percentages, i get ‘undefined’ error.

Here are all possible combinations for my unit:

Unit: R-5 RA5 sw RD5 ver.: 2.03.25

If possible we should find a way that is automatic so that the integration detects and chooses the right method automatically. It is hard for me to do it without the access to the unit. If someone provides me the access via port forwarding I can probably get it work.

Hi, I have the same unit and use the same constant flow setting. A workaround is to set fan speeds as: 30,31,32,33,34,35,36,37,38 The values have the following meaning: . This works but it is far from ideal. Many changes would be needed in the code to allow values < 12 and also in the library.

Hi can you add or replace to const.py DEFAULT_FAN_MODE_LIST = "10,11,12,20,21,22,30,31,32,33,34,35,36,37,38"

To utils.py if not fan_mode.isnumeric() or int(fan_mode) < 1 or int(fan_mode) > 100:

and climate.py async def async_set_fan_mode(self, fan_mode): fan_percent = int(re.sub("[^0-9]", "", fan_mode)) if fan_percent < 10: fan_percent = 10 if fan_percent > 100: fan_percent = 100 if fan_percent >= 10 and fan_percent <= 100:

Hi, i have the same unit (Duplex RA5) with the same speed issue. I got it to work, sort of, but i would love to get it to show correct names for the speeds etc. I have a meeting with the installer company, so i will ask about how to determine which speed it should be using at what parameters. I can get you access to the unit when i learn more about the issue.

Ok i know more. The reason i need the norm/norm etc is for equal preasure ventilation setup. Same amount of air in as out. Then you have to control it via these name presets and not with power percentage. I am from CZ, so we can switch to local language :) . I can give you access to the unit if you have time for it. I can write you an email so we dont spam this thread.

Edit: The parameter H10510 has to be 4. If it is 4 then it is controled via modes and not power of fans.

Hello!

Any updates on this topic? I would also love to have the correct labels for the values!
