3.3. TROUBLE SHOOTING

3.3.1. Error Code Table

3.4. RECOMMENDATIONS FOR ECONOMICAL USE 

OF THE BOILER

Your boiler is set in ECO mode for economical use, it is not 

recommended to change this setting.

Selection of Right Capacity

Heat loss of the ambient where the boiler is to be used shall be 

properly calculated, and boiler capacity shall be set accordingly. 

Appliances not having sufficient capacity will respond to demand more 

slowly, and appliances with higher capacities will lead to discomfort and 

more fuel consumption as they will be activated and deactivated more 

frequently. Therefore, suitable boiler capacity for the ambient to be 

heated. 

Insulation

Insulation of your building is the most important factor preventing 

heat loss and reducing gas consumption. In addition, the insulation of 

your boiler is the thickest insulation within its class, thus heat loss is 

minimized.

Radiators

Adjust the radiator valves to balance pressure distribution of the system 

in your house. Placing furniture in front of radiators causes discomfort 

and higher fuel consumption. Reducing radiator valves or turning into 

the lowest position (thermostatic radiator valves) for the rooms which 

are not used for a long term, provides energy-saving. 

Hot Domestic Water

If you are using the boiler with a hot domestic water boiler, it is 

recommended to set the Hot Domestic Water temperature as (38~42 

°C). Setting the water heater to a low value provides a large amount of 

energy saving.

Thermostatic Radiator Valves 

Use of Thermostatic Radiator Valves ensures balancing thermal 

distribution within your house, thus provides energy saving and comfort.

Room thermostats 

Room thermostats allow setting ambient temperature for comfort and 

economic times, thus your boiler will operate more economically. Thus 

you can set your room temperature as you want, and make energy 

saving by 6% with each degree reduction.

Ventilation

Do not leave the windows half-open to ventilate room(s). In this case, 

while there will be no significant improvement in the room air quality, a 

continuous heat loss will take place. Opening windows fully for a short 

term gives more effective results.

Turn the thermostatic Radiator Valves to the lowest position when 

ventilating rooms.
