Memory backup function after power failure
If there is a sudden power failure, the heater's current operating time settings are retained
at the time of power failure. When the power is restored, the heater automatically turns on
and returns to the previous operating mode, except for the time, which must be set again.
In order for the memory backup function to work, any changes to the heater settings must
be made. By default (when nothing has been set and the heater has only been connected to
the power supply), the memory backup function is not enabled.
After pressing and holding the on/off button for 10 seconds, the heater settings will be
restored to the factory settings, i.e. (temperature in comfort mode - 19°C, temperature in
economy mode - 15.5°C, time - 12:00, day of the week - 1 (Monday), P1 - P7 - initial settings,
temperature measurement calibration - -2°C, open window detection function - 0, anti-
scalding function - oF).
The next item is the F3 function, which does not affect the operation of the heater. Skip
setting it by clicking the
V button.
Open window detection function (F1)
If the room temperature drops by 5°C within five minutes, the heater will operate at a
temperature setting of 10°C for a period of time. This time is selected by the user. It can be
60 or 90 minutes. After the set time has elapsed, the heater will return to the operating
mode that was active before the open window detection function started. In the settings
menu, press
V until (F1) appears on the display. Use the + and - buttons to select the time (0,
60 and 90 minutes) after which the heater should return to the active operating mode
before the open window detection function is activated. Setting the value to 0 deactivates
the function. The default value is 0. Press the
V button to save the settings and go to the
next menu item.
Anti-Scald function (F2)
If the surface of the heater reaches the temperature assigned to the anti-scald function,
heating will be stopped until the temperature of the surface of the heater drops. Press the
+
button to increase or – to decrease the temperature assigned to the anti-scald function. You
can choose from the following temperature settings: 40, 45, 50, 55 and 60°C. Setting the oF
value disables the function. oF is the default value. Press the
V button to save the settings
and move to the next menu item.
When the open window detection function and the anti-scald function are turned on at the
same time, only the open window detection icon will appear on the display. However, the
anti-scald function will be enabled.
