Note regarding temperatures that are too high:
In order to protect the electronics from temperatures that are too high, the
pump's power, and thus the flow of water that is too hot, is automatically
reduced. The temperature is measured directly at the electronics. When the
temperature of the electronics is between 105 °C and 115 °C, the pump power
is continuously lowered toward minimum power from the power specified on the
power selector switch. The pump automatically stops completely at 15 °C and
automatically restarts at 115 °C, when the electronics have cooled down, begin-
ning at minimum power. As cooling down proceeds further, the power continues
to be adjusted, up to the value that is set.
