Button off problem on Shelly plus1

Hello everyone, I'm facing a problem with Shelly plus1, I have my device set-uped as button, "Momentary" switch and connected to air conditioner brand Fujitsu RD-25FB with control unit UTY-RNNUM.. The problem is that when I start the air-conditioner I'm successful but when I try to turn the air-conditioner off nothing happens. (as i show in the video) But when I turn it on again it turns off. I would like to connect my Shelly device to thermostat and setup some weekly programming but cannot move on.

I would need a bit more help than link to some script, I'm learning programming, but am still newbie.

Thanks Karel

Dear Moderator,

Thank you for your fast response, the video has only 50sec and it says more then thousand words, but i get that you don't want to watch it :). The Air Conditioner is Fujitsu RD-25FB and control unit is UTY-RNNUM.

With old Shelly 1 you could easily work with the length of button press in setting (witch may or may not be the problem).

I hope that is all the information you needed, Im going to add it to my first post too.

Thank you again Karel.

Hello.

The wiring diagram was attached.
