Start-up
Heating mode is possible with or without water
content depending on the operating mode.
Hot water mode
This operating mode can only be used if the boiler has
been filled.
Devices with electrical heating elements
Select diesel or electrical mode using the power selector
switch. Illumination of the yellow LED (o) at the power se-
lector switch indicates that the unit is operating with 230 V.
Mixed mode (gas or diesel and electrical mode) is not
possible in hot water mode. With this setting the unit
automatically selects electrical mode with a preselected
power setting of 900 W or 1800 W.
Move the rotary switch on the control panel to position
(c - hot water mode) 40 °C or 60 °C. The green (b) and
yellow (g) LEDs light up.
After reaching the set water temperature (40 °C or 60 °C), the
heating system will switch off and the yellow LED (g) will be
extinguished.
Heating and hot water mode
Devices with electrical heating elements
Select gas, diesel, electrical or mixed mode using the power
selector switch. Illumination of the yellow LED (o) at the
power selector switch indicates that the unit is operating
with 230 V.
– Heating
with
water temperature monitoring
Move rotary switch on control panel to “On” position (e).
Set the rotary switch (a) to the desired thermostat setting
(1 – 5). The green LED (b) for operation is lit and simultaneous-
ly indicates the position of the selected room temperature. The
yellow LED (g) indicates the water‘s heat-up phase.
The unit automatically selects the required operating level
according to the temperature difference between the set-
ting on the control panel and the current room temperature.
When the room temperature selected on the control panel is
reached, the heating system switches back to the smallest
setting and heats the water to 60 °C. Once the water tem-
perature is reached, the heating system switches off and the
yellow LED (g) goes out.
– Heating
without
water temperature monitoring
Move rotary switch on control panel to “On” position (d).
Set the rotary switch (a) to the desired thermostat setting
(1 – 5). The green LED (b) for operation is lit and simultaneous-
ly indicates the position of the selected room temperature. The
yellow LED (g - water heat-up phase) will be lit only when the
water temperature is below 5 °C!
