Two A/C units are close to each other and turning one on turns the other on. How to fix?
I have 3 units air con of same brand in my office room. So all 3 units will turn on/off at the same time, by single one remote control. So I used a brown tape to cover the signal emitter to weaken the signal strength, and it works. But i have to place the remote control very near to the relatively air con, and i can control each air con individually.
