To prevent erroneous settings, the described switch-on and switch-off values are interlocked,
this means they can be set only at a specific value to one other.
Since with this diagram, speed controls are only useful when the objective is "absolute
temperature", this control objective has been saved both in the settings "Absolute temp." and
also "Differential temp.". The control devices are therefore dependent on this setting.
