Panasonic A75C3208 Remote #185

Open barchasse38 opened 3 weeks ago

barchasse38 commented 3 weeks ago

Hello,

Thank you for the project and the work accomplished.

I'm trying to control a Panasonic Inverter, the remote part provided in the manual is CWA75C3208.

I tried all the Panasonic protocol provided in the project and none of them was entirely satisfactory.

DKE / LKE / JKE / NKE works for the mode selection (OFF / HEATCOOL / HEAT / COOL / DRY) but the temperature selection doe not ; -Selecting the minimum temp send the max temp to the inverter -Selecting the maximum temp send the min temp to the inverter -Selecting other temp does nothing.

Could the problem be with the hardware? Or it just means that the remote use another protocol ?

If so I want to try to decode this new protocol and share it on the project.

Thank you for your help

Hi, it's probably a protocol issue. It seems that on every model Panasonic does some minor tweaking to the protocol. I friend of mine has a couple of years old Panasonic on this summer cottage, and I just could get any sense out of the protocol. We finally ended up sending recorded signals, instead of trying to understand what they do.

Hi Toni,

Thank you for your quick response.

I will try to understand how the protocol works by testing this week-end, I will let you know how I progress and I will try to implement it in the project.

Regards
