1. In case of wrong faulty expansion tank the system pressure may exceeds the safe value at high temperature which leads to the activation of safety valve If this occurs in the cold boiler the pressure may falls below the minimum level thus an electronic failure indicated on the display In case of faulty expansion tank it has to be changed ELECTRICAL WIRES AND CONNECTIONS CONTROL Have to be checked the status of internal electrical wires and their proper distance from any of hot spare parts Have to be checked the electrical connections at sensors pump and the engine for three ways valve HEAT EXCHANGER CONTROL In a well adjusted appliance the heat exchanger does not need any special maintenance Have to be checked the fume ways and if there are soot or subsidence it is neccessary to clean the whole heat exchanger The subsidences make more difficult for the fume to going out through the chimney furthermore worsen the heat unload ability thus the efficiency of the heat exchanger reduces In case of smaller contamination it is enough to remove the burner and clean the fume ways of the heat exchanger through the burner slot In this case make sure that the water can leak by the condensing syphon to the right place In case of huge contamination of the heat exchanger it could be taken out from the appliance It is necessary to remove the condensing plate before the extensive cleaning of the whole heat exchanger Have to be checked2. boier USER S MANUAL DIGITAL DISPLAY OVERVIEW A Domestic hot water operating mode B Burner output indicator C Service reguest call your service partner D Pressure indicator E Solar operation mode F Temperature indicator G Heating operation mode H Reset press the Reset button Number Code display The digital display has a blue backlight The backlight turns on by pressing a button and turns off automatically after 15 seconds if you do not press any of the button OPERATING MODES HANDLING Status OFF Ignoring heat requests except for domestic hot water and frost protection of heating To activate the mode press the E marked button Status STAND BY In OFF status press the E marked button to change to Stand by and chose from the following modes Winter Domestic hot water and heating operation are allowed Summer Only the domestic hot water is allowed SLG Falcon wall hang condensing gas boiler USER S MANUAL Room thermostat or OpenTherm controller unit are suitable to indicate the heating reguest for the boiler controller The sensors closing in room thermostat indicates the heat reguest for the controller pesa In winter operation mode the display shows a possible status of a valid heat request If a higher priority request is received the process is discontinued and the controller changes to serve the higher priority request
