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

Re: Thermostat deadband
Okay....
Assume we are trying to cool.
Set point = 20°C
Temperature rises to 21°C, cooler switched on.
Temperature drops to 19°C, cooler switches off.
21° - 19° = 2°K
Therefore deadband is 2°K; the temperature needs to change by 2°K before anything happens.Brian - Newton Abbot, Devon, UK

Re: Thermostat deadband
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

Re: Thermostat deadband
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.)Last edited by mikeref; 02-11-2016 at 07:54 AM. Reason: Added some
