I don’t know why my split system does this but I can’t change it from heating to cooling.

To get around it I have to go into my bed room and set that one to either heating or cooling with a remote then walk back into my living room and using that remote turn on the system and it’ll be set to whatever setting I used in the bed room.

If I try and directly move from heating and cooling the split system will double beep at me and won’t switch or turn on.

Frustrating to say the least.
