Wherein the other set point should be slightly smaller than the set point. Similarly, the temperature in the cold storage pool corresponding to the constant temperature cooler can be stabilized within a certain range. The control button may be provided separately or together with the display 105, preferably together, to facilitate the setting of parameters by the operator.
