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 125 °C and automatically restarts at 115 °C,
when the electronics have cooled down, beginning at minimum power. As cooling down
proceeds further, the power continues to be adjusted, up to the value that is set.
Malfunctioning pumps can be returned to the manufacturer's address. The manufacturer
will refuse to accept packages with unpaid shipping or invoices for repair. The
manufacturer grants a two-year guarantee under the condition of correct installation and
proper use.
