. SAFETY SYSTEM OF THE DEVICE

MAKTEK OMEGA ELECTRIC BOILER ; 

has the following safety features in order to 

ensure the highest level of safety and highest technology.

7

.1 

RCD DEVICE (

SHORT CIRCUIT RELAY

)

In case of short circuit, the relay shuts off the electricity connection and prevents any 

possibility of electruction  and prevents any harm to people or the device.

7

.2 HEATING TANK 

FLOAT

 LEVEL SENSOR (H6)

This sensor prevents the boiler from running without sufficient water inside the heating tank 

therefore avoids any damage to the resistances. In case of low water level, H06 is 

displayed on the device's screen. The air trapped must be completely removed from the air 

vent valve which is placed on top of the device. If the water pressure drops after the air is 

taken, the display shows H03. In this case, water should be added from the filling valve.

7

.3 LOW WATER PRESSURE

If the pressure at the heating circuit is below 0.7 bar, the boiler will not operate and the H3 

warning code will appear on the digital display,preventing damage which causes from 

running without water.

What to Do: 

The heating system pressure is increased by adding water up to the desired 

level by the filling valve. You can view the pressure of the water filled from the manometer.

7

.4 OVERHEAT LIMIT THERMOSTAT

If the water temperature at the heating system is above 95°C, the system energy is cut off 

by the card and the H5 warning code is shown on the digital screen.

What to Do:

 When the water temperature of heating system drops down to 60°C, the 

boiler will start working again. If this failure occurs two times consequently, please call an 

authorized service.

7

.5 FROST PROTECTION

When the temperature in the heating system drops down to 5°C, there is security system 

that automatically activates the resistances When the water temperature reaches 40°C, 

activation of resistances are stopped.

In order for this system to work, the main switch to which the device is connected must be 

switched on and the heating and hot water selector switches must be set to the minimum 

setting.
