5. 1 Commissioning 1. Filling the system with water 5. Slowly turn the filling valve to open position until pressure reaches a value around 0. 8 bar for system heights up to 6 meters. For longer system heights, use the table on the previous slide to determine filling pressure. Filling operation should be done slowly. When pressure exceeds 0. 8 bar, error code will disappear and the status indicator light will turn to blue. Close the filling valve. The system pressure value can be monitored from the user interface. 6. Make sure the automatic air vent valves located on the pump and heat exchanger are opened. Vent the air from the installation with the manual air vent screws on the radiators. Make sure screws are tightened after venting. 7. If after the venting the pressure decreases below 0. 8 bar, refill with water until the pressure reaches 0. 8 bar again. 8. Check for leakages. 5 Configuration & Commissioning - Internal use only

5. 3 General Settings 3. 1 P-level Service parameters DHW Solar Function Parameters The boiler checks 2 things to operate for DHW when solar tank is connected; 1.

5. 3 General Settings 3. 1 P-level Service parameters DHW Solar Function Parameters The boiler checks 2 things to operate for DHW when solar tank is connected; 2. Boiler estimates temperature value according to solar tank temperature, water flowrate and boiler minimum allowable capacity. The boiler operates if “DHW set value + 5 Kelvin > Ts DHW. Reason for this requirement is to prevent discomfort due to difference in temperatures between desired DHW temperature (DHW set value) and real DHW temperature. Ts DHW: estimated DHW outlet temperature after burner operation at minimum boiler capacity.

5. 3 General Settings 3. 2 C-level Service parameters C-level gives access to the SCOT-parameters (Safety combustion technology system). The SCOT-system is a part of the PCB which provides continuous control of combustion efficiency and combustion performance. It is sometimes also called Lambda-Gx system. Due to the SCOT system, the gas valve operation is independent of the fan, so there is no need for gas valve adjustment to optimize gas/air ratio. It opens/closes the gas valve based on the flame quality. 60 Configuration & Commissioning - Internal use only
5. 3 General Settings 3. 2 C-level Service parameters SCOT parameters are read-only. In order to make changes in menus C 0 to C 5 an additional password has to be input. Scroll to parameter C by using the left dial 61 Scroll to parameter CE by using the right dial Give in the password: 115 by using the right dial, confirm every digit with the Enter key Configuration & Commissioning - Internal use only Push Now C 0 to C 5 is adjustable.
5. 3 General Settings 3. 2 C-level Service parameters C 00 Gas type This setting is used to switch between fuel types. Default is Natural Gas. C 01 Adjustment of gas start offset This setting adjusts gas amount before ignition. Adjustment can be made in range of -9% to 20%. Only used if there is serious ignition problems. When this setting is increased, the starting gas mixture will be enriched, which will help delayed ignition problems. C 02 62 Adjustment of startup capacity This setting adjusts ignition capacity (both gas and air flowrate) to ensure that ignition takes place. Adjustment will be done as trial and error in the field. 2% increment is recommended at each trial. To much increasing may cause loud ignition. Configuration & Commissioning - Internal use only
5. 3 General Settings 3. 2 C-level Service parameters C 03 C 04 C 05 63 Flue duct adjustment This setting is used to adjust appliance to long flue pipe lengths. This parameter can only be adjusted to ‘ 3’ in case of C 13 x and C 33 x types of flue systems. Adjustment minimum capacity This setting adjusts the minimum capacity of the boiler. Default minimum capacity is 3 k. W. This setting is only used if there are flame loss faults in heavy windy locations. Gas control offset Adjusted by the PCB automatically after calibration and adaption. If there is a combustion problem after ignition and stabilisation, this parameter must be adjusted to factory setting (29, 3). This value will be changed by PCB automatically afterwards. This parameter is not related with service. Configuration & Commissioning - Internal use only

5. 3 General Settings 3. 2 C-level Service parameters C 12 Reducing ion base value If CO 2 percentage is below standard limits, this parameter value must be increased to obtain a CO 2 value inside the limits. C 13 Reducing ion at minimum capacity If CO 2 percentage is below standard limits, at minimum capacity, this parameter value must be increased to obtain a CO 2 value inside the limits. 65 Configuration & Commissioning - Internal use only
