Tado V3+ AC issue with Mitsubishi AC

I have an issue with Tado V3+ to control a Mitsubishi AC, model MSZ-GB50VA with KM05E remote controller: some of the temperatures setup with Tado app are not sent to the AC, heat mode or cooling mode.

I can, for example, setup 21ºC heat mode, but I can’t setup 22 or 23ºC. I can see that Tado is doing the change on its screen, but no confirmation bip on the AC. Same issue with cooling mode.


Any idea ?
