2.3 OPERATION PRINCIPLE OF THE DEVICE MAKTEK Omega LCD electric combi boiler provides central heating with the use of panel radiators or underfloor heating pipes. The primary heating circuit water is heated in the main heat exchanger with the heating elements. The hot water circulates the installation with the help of the circulation pump, delivering hot water to the radiators or underfloor heating pipes.
2.4 MAIN FEATURES OF THE BOILER • MAKTEK Omega electric combi boiler uses ONLY electricity as fuel. • Electricity as fuel for heating has no emissions and %100 environment friendly. • There is no heat loss in electric heating. Unlike combustion systems with fossil fuels, there is no chimney therefore no heat loss from the chimney with hot fumes.

50-100kW Circuit Breaker Blue *In 50-100kW models, the RCD device is mounted inside the boiler. The connection between the RCD and the main circuit braker should be made with a suitable dimension cable (see table for electricty connection parameters) and according to the diagram above. The cable connections are clearly marked on the cables to be connected to the RCD device.
3.9 ROOM THERMOSTAT CONNECTION An electric terminal is left outside the control panel plastic box so that the control panel is not opened while connecting an optional room thermostat. You can see this terminal in the below picture. Remove the jumper cable and connect the room thermostat volt free cables.
4. COMMISSIONING 4.1 FILLING WATER TO THE SYSTEM a) Make sure that the automatic air vent valve on the circulation pump is loose. b) Turn on the filling valve and fill water until the pressure reaches 1.5 bars on the LCD screen.
4.2 STARTING UP First time operation of the boiler must be done by authorised service personel in order to validate the guarantee of the boiler and to ensure the boiler runs efficiently and safely for many years. Authorized service personnel will check all requirements in the startup request form, which must be filled by the installer before the service comes to validate the boiler for first time operation.
