6. SAFETY SYSTEM OF THE DEVICE
MAKTEK Omega Electric Combi Boiler
has the following safety features in order to
ensure the highest level of safety and highest technology.
6.1 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.
6.2 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.
6.3 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.
6.4 OVERHEAT LIMIT THERMOSTAT
If the water temperature at the heating system is above 93°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.
6.5 SHORT CIRCUIT THERMOSTAT
This is a secondary safety measure to prevent overheat in the boiler. If the overheat
thermostat does not function and the boiler temperature reaches 96°C, short circuit
thermostat conducts neutral to the boiler chasis and the RCD device shuts off the electricty
supply.
