Explanation of this in the least scientific jargon free way possible?
Many appreciations

Okay....

Assume we are trying to cool.

Set point = 20C

Temperature rises to 21C, cooler switched on.

Temperature drops to 19C, cooler switches off.

21 - 19 = 2K

Therefore deadband is 2K; the temperature needs to change by 2K before anything happens.

Air conditioning controllers have an effective dead band, in between heat cycle differential and the cooling cycle differential. So when in dead band neither heating or cooling is activated, dead band could be around 2> 3 degrees C

I can see OP questioning Degrees K Brian.
So 21 degrees C - 19 degrees C = 2 degrees C deadband. ( or 2 degrees on the Kelvin scale.)

True, thanks Mike
