What Is Temperature Hysteresis?
As you watch your Temperature History Graph on your app, you may see that the air temperature in your cooler
behaves like a “wave” that goes up and down around your set point. This is completely normal for any refrigeration
system. Hysteresis is the difference in the On and Off temperatures of your cooler as it cycles.
On a perfect scenario, as soon as the refrigeration system reaches the set point (e.g. 38°F) it would turn off
immediately, warm up a bit (e.g. 38.01°F), and then turn on again, and at 38°F it would turn off again. The end result
would be something that is continually turning on and off. This constant starting and stopping would wear the
refrigeration system out and it would fail in a short period of time.
Hysteresis is not only normal but necessary to avoid this frequent On and Off cycling. Hysteresis is dependent of
many factors including calibration of equipment, response time of temperature probes, CoolBot settings, etc.
The hysteresis value on a CoolBot cooler that has been designed following our recommendations and with a
controller set to factory settings is normally around +/- 2°F from the set point.
Hysteresis in your cooler may be of a higher value and that is not a bad thing. Just adjust your set temperature so that
the high and low values stay within acceptable ranges for your product. Remember that the sensors of the CoolBot
are very sensitive to air changes, and the fact that the air temperature changes rapidly at a given point, doesn’t
mean that your product is changing temperature at the same rate.
Your product has significantly more mass than the CoolBot sensors and it will take a much longer time to gain
temperature when exposed to higher air temperatures.
If you were to measure your product temperature you would see that it remains essentially constant while the air
temperature in your cooler fluctuates up and down.
