Outdoor Unit Low Noise

[ptruman]

It's winter, so having all my Indoor Units on heat makes the Outdoor Unit "noisy" :)
Tried setting "Low Noise" (from one device) and the UI showed it set, then unset about 5 seconds later.

Using the remote works. Not looked too hard yet, but logging for now.

Ok - tried a manual command and ou_low_noise does exist as a query parameter, but when I've set it on a remote, and queried via POST, the value remains 0

How many indoor units do you have? I believe low noise mode is only available if you have a single indoor unit. I have 2 indoor units and see the same behaviour as you.

[ptruman]

4 internal, 1 external - and I can't see anything about it not being able to used with multiple IU? Have you got a manual page showing that?

Its better to manually set the AC to low noise using the DIP SWITCH on the pcb

Just change it back when the winter is over

[ptruman]

Just to update - according to my manual, the OU Low Noise is only selectable when there is 1 (single) IU. Multiple IU = "cannot be set". I doubt the integration will know that more than one IU is linked to the same single OU - but if it could, it could be "hidden"

Actually I got a single indoor unit, and got the same behavior : switch going off automatically after 5 sec.

I'll check the switch settings on the outdoor unit

I unfortunately have 5 heads so I'm unable to test. One thing I'm noticing is the ou_low_noise key does not return a value (it may be my model does not support at all). I wonder if the ou_low_noise parameter is only gettable in single-head setups?

[ouafnico]

Can I test anything ?

If you're comfortable running curl commands, can you check the output of

curl --no-progress-meter -X POST --data '{"device_id":"<DEVICE_ID_ALL_CAPS>","device_sub_id":0,"req_id":"","modified_by":"","set_level":"03","list":["ou_low_noise"]}' 'http://<DEVICE_IP_ADDRESS>/GetParam'

Be sure to replace DEVICE_ID_ALL_CAPS and DEVICE_IP_ADDRESS

[ouafnico]

Sure, but what is DEVICE_ID_ALL_CAPS ?

[ptruman]

Unit MAC address

[ouafnico]

Thanks/
I got this :

$ curl --no-progress-meter -X POST --data '{"device_id":"10:68:XX:XX:XX:XX","device_sub_id":0,"req_id":"","modified_by":"","set_level":"03","list":["ou_low_noise"]}' 'http://A.B.C.D/GetParam'
{"result":"NG","error":"0002"}

[ptruman]

Remove the colons from the MAC address

[ouafnico]

Better:

{"value":{"ou_low_noise":"0"},"read_res":"ack","device_id":"XXXXXXXXXX","device_sub_id":0,"req_id":"","modified_by":"","set_level":"03","cause":"","result":"OK","error":""}
