Rate Of ChangeTo calculate rate of change for a particular condition, take the difference between the Start Temp and End Temp and divide by the Transition Time.Cool Down Example (empty): From +85°C to -40°C = 125°C / 28 min = 4.5 °C/min.Cool Down Example (with 80 lb. load): From +85°C to -40°C = 125°C / 48 min = 2.6°C/min.Heat Up Example (empty): From -40°C to +85°C = 125°C / 17 min = 7.35°C/min.Heat Up Example (with 80 lb. load): From -40°C to +85°C = 125°C / 29 min = 4.3°C/min.
