The instantaneous water heater CEX-U / CEX7-U / CFX-U / CEX / CEX7 / CFX
is a electronically controlled, pressure-resistant water heater for a decentral-
ised hot water supply to one or more outlets.
Its electronic control regulates the heating power consumption depending
on the selected outlet temperature, the respective inlet temperature and the
flow rate, thus reaching the set temperature exactly to the degree and keep-
ing it constant in case of pressure fluctuations. The required outlet tempera-
ture can be entered via key press within a range between 20 °C and 60 °C and
can be read off the digital display.

It is possible to use the instantaneous water heater in combination with an
external load shedding relay for electronically controlled instantaneous water
heaters or a prepared load shedding box to operate the appliance along with
an electromechanic cooker (refer to installing instructions).
