4) Position of Central Heating Circuit:
In order to activate winter position, in other words the central heating circuit on the boiler, you can
set the temperature of exiting water in between 30-80°C through the adjustment knob. The set value
is seen on the LCD display, the ignition operation automatically steps in order to ignite the boiler, and
the device starts to heat up the water in the central heating circuit until a requirement for domestic
hot water. In case of failure of ignition, the device repeats the automatic ignition operation for 3
times. In case of failure of these three ignition attempts, the device stops itself by giving the warning
of “No Flame Signal”. Er 13 error code is displayed as flashing on the LCD display, and informs locking
of the device. In order to resolve this, press on the Reset button. If the locked status of the device
is persisting despite pressing on the Reset button, see the Determination and Resolution of Error/
Malfunction section on page 38.
5) ECO Mode:
The boiler central heating circuit operates under two different modes as being Standard Mode / Eco
Mode. In Eco mode, the device operated with modulation as in the Standard mode, but the heat
requirements are being assessed by special parameters formed for Eco mode, and the boiler adjusts
its operation.
When the boiler operates in Eco mode, the radiator symbol and ECO symbol under it becomes active
on the display. And in standard mode only the radiator symbol is active.
And the Eco mode is only for the central heating circuit. It has no effect on the domestic hot water.
Fuel saving will be ensured when the device operates in Eco mode.
