The first line is written on the warranty card, and each device has a label with all the technical data on the inside edge.

The boiler has stopped due to an error. It is possible to find out the cause of the error by the flashing frequency. Restarting is done by pressing the danger triangle, must be pressed for at least 3 seconds. After that, a new boot will take place. The boiler usually stays on. If the error persists, call 5272262

The boiler has stopped due to an error. The code on the number plate indicates the boiler error. Restarting is done by pressing the danger triangle, must be pressed for at least 3 seconds.

Hot water is made according to the program entered by the factory from 5.00 to 22.00. After 22:00, a boiler full of hot water can be used, new hot water production starts at 5.00. The corresponding program can be changed from the right channel of the clock.

Electrical fault, boiler electrical input: L – phase, N – zero. If the opposite is the case, place correctly if zero is not required to install a isolating transformer. Call 5272262

Electrical fault, boiler electrical input: L – phase, N – zero. There are areas in the Old Town where there is zero electricity. This error can be eliminated by installing a isolating transformer. Call 5272262

Scale has formed on the surfaces of the domestic water heat exchanger, it does not transfer heat to the domestic water. The heat exchanger needs to be washed with acid solution. Consult a technician who has the appropriate washing machine. Call 5272262

The pre-pressure has disappeared from the expansion tank. It can be measured when the boiler pressure is 0 bar. As the water heats up, it expands and if there is no pre-pressure in the expansion tank, the water pressure increases, when the water cools, the water pressure drops. It is necessary to pump the pre-pressure in the expansion tank. Call 5272262.

The gas release button must be held down for a short time (approx. 30 sec) and the spark button pressed several times. If it still does not light up and more than a year has passed since the last maintenance, call 5272262.

The flame has started to soot, the combustion air openings are full of dust, the heat exchanger is sooty. Call 5272262.

You can, but you need to check the requirements in the device manual.

If the boiler is equipped with automatic heating with room temperature sensor or automatic room temperature control, this is done automatically, otherwise the heating thermostat knob must be turned to the left position (sunshade).
