* Hot water mode
In hot water mode, the heater automatically selects electric
mode with the preset electric power of 900 W or 1800 W. If
the 230 V power supply is disconnected or fails, the heat-
er automatically switches over to diesel mode.
Heating mode:
Electric mode has priority in heating mode. If the electrical
heating output is insufficient, diesel mode is enabled.
Switching on the electric heating elements as well
does not increase the maximum heating power.
