tric storage heater, for example).
2 Control contact drops out when switching the instantaneous
water heater on.

15.3 DHW output

The DHW output is subject to the mains voltage, the appliance's
connected load and the cold water inlet temperature. The rated
voltage and rated output can be found on the type plate (see
chapter "Operation / Troubleshooting").
Connected load in 38 °C DHW output in l/min.
