6. Description of appliance
The instantaneous water heater CEX -U is a microprocessor-controlled, pressure-resistant water heater for a decentralised
water supply to one or more tap connections.
Its electronic control regulates the 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 keeping it constant in case
of pressure fluctuations. The required outlet temperature can be entered between 20 °C and 60 °C and is indicated on the
digital display.
This appliance may be able to be used with a Thermostatic Mixing valve or where serving a fixture that does not require
temperature limitation such as a commercial Kitchen sink or Cleaners sink. Refer to AS/NZS 3500.4.
7. Operation
The appliance switches on automatically when the hot water tap is opened and switches off
automatically when the hot water tap is closed.
Temperature setting
The required outlet temperature can be
adjusted gradually to a higher or lower value with the up arrow and down arrow keys.
Pressing a key once briefl y changes the
temperature by 0.5°C between 35°C and 42°C and by 1°C outside that range.
Pressing a key for a longer time changes the temperature continuously.
The required outlet temperature can be adjusted between 20°C and 60°C.
Note: reducing the temperature below 20°C displays “- -” and the heating function will not oper-
ate.
Program buttons
The two program keys allow a preset
temperature to be selected quickly.
The factory setting is 35°C for program 1 and 48°C for program 2.
The preset temperature can be changed to the current temperature setting by prolonged
pressing of the program key.
The display changes from “P1” or “P2” to the new temperature value which becomes
available each time the corresponding program key is pressed.
