We need to remember that the brain is the unit hanging in the garage. It remembers what is was told. If it is misbehaving it is because it remembers something bad that it was taught right or wrong. Fortunately it can be untaught with in a pin in the wall control unit. But normally the bad actor is the hand held control. All to often , they are coded the same in neighborhoods with a similar code. Give the handhelds a unique cod and all should be well when you clear the brain and give the new units access.
