15.3 CONTROLS AND SETTINGS
All controls of the heater are carried out using the front panel with the capacitive touch buttons described
above.
15.3.1 TURNING THE HEATER ON
On initial start-up, the heater is off by default. This can be recognized by the Switch 1 icon slightly backlit
to make it easier to find in dark places.
The heater can be turned on by pressing the switch icon (1). At this moment, the individual segments of the
thermometer (3) light up gradually. Then they all go out and if no error is detected, the current water
temperature is displayed.
The turned-on heater can also be recognized by the backlit power icon and the current temperature on the
thermometer (3) is backlit too.
15.3.2 TURNING OFF THE HEATER
The turn-off procedure is similar to turning on, but here the switch button (1) must be held down longer.
When the button is pressed, all segments of the thermometer (3) light up, and then they gradually fade away.
After the last segment goes out, the heater is turned off completely. However, if the switch button (1)
is released earlier, the heater remains unchanged. This functionality is used to prevent accidental shut-down.
The minimum time of the power button being pressed is approximately 1.5 seconds.
When the heater is off, all icons are out, except for the power, which is slightly backlit.
15.3.3 TEMPERATURE SETTINGS
The thermostat temperature is set using the control button (4). It can be operated in two ways. Either briefly
press the + and - buttons or swipe the line between the buttons.
The temperature can be set in increments by 5 °C, when the thermometer (3) shows the currently set value
by flashing segments. When the setting is finished, the currently set temperature continues to flash for 3
seconds and then it is stored in the thermostat.
15.3.4 SETTING THE OPTIMAL TEMPERATURE
The Optimum icon and button (2) are used to quickly set the optimum temperature. If this button is pressed
the thermostat is set to the optimum temperature of 55 °C, when the heater achieves the highest efficiency.
The optimum temperature setting is indicated by a green icon.
