33 Regulation of

33 Regulation of Domestic hot water To obtain Domestic hot water, press the button COMFORT COMFORT 28 (yellow LED comes on) To adjust the Domestic hot water temperature in winter or summer operation, use the knob 33. It is possible to determine the temperature of water stored in the tank between 40°C and 70°C. COMFORT 28 32 Interruption of heating To interrupt heating, turn the knob 32 to the sun position . The boiler will continue to operate in the summer position to provide Domestic hot water only. ON/OFF Switch-off procedure To switch the boiler off, press the button ON/OFF 26. Close the gas tap located under the boiler and move the boiler external power supply switch to the OFF position. Afficheur gauche COMFORT Afficheur droit Display: display of current operations During operation of the boiler, in other words when it is performing its normal functions, the left side of the display shows a series of characters referring to the operations, as indicated below: 0 No heating command C Heating Rc pump in post-circulation mode for heating d Domestic hot water h Pump in post-circulation mode for Domestic hot water b Tank reheating On the right, the display shows (2 characters): - in heating mode: heating installation output temperature - in Domestic hot water distribution mode: drawing-off temperature. - in tank reheating mode: tank temperature or drawing-off temperature. 4. ANTI-FROST DEVICE 5. MAINTENANCE The boiler is fitted with a device, which in the event that the water temperature falls below 8 o C the pump activates and runs until a temperature of 18 o C is attained. In the event that the water temperature falls below 3 o C, the diverter valve switches to Domestic Hot Water and the burner fires on minimum power until a temperature of 33 o C is attained.s This device is only activated when the boiler is operating perfectly and - the system pressure is sufficient; - the boiler is powered electrically; - gas is available. Schedule an annual maintenance check-up for the boiler with a CORGI registered Service Engineeer in the UK and with a competent person as described in I.S.813 for IE. Correct maintenance always results in savings in the cost of running the system. 6

6. TROUBLE SHOOTING This boiler is fitted with safety devices which are activated in certain situations and cause the boiler to stop operating. CONDITIONS FOR STOPPAGE OF THE BOILER COMFORT There are two types of stoppage: - Operating failure (A) - Safety stop (E) OPERATING STOPPAGE "A" This type of stoppage is displayed in the form of a number preceded by a letter (A) as shown in the following table. To clear this type of stoppage, press the reset button (Reset). In the table, each error code is associated with the problem causing it to appear. In the case of error A 02, before calling a qualified technician, check the pressure gauge to see if the water pressure in the appliance is 1 bar. If necessary, restore the pressure using the filling valve located under the boiler and perform an ON/OFF operation by pressing the button. If the pressure falls frequently in the appliance, have a plumber check for water leaks. N.B. Warning! The boiler is always connected to an electrical supply. AFFICHEUR A01 A03 A07 A17 A18 A33 A97 A98 A99 CAUSE Three ignition attempts The output temperature exceeds 105°C during operation Too many flame separations over a period during operation Input water circulation fault No water circulation Fan problem Electronic control problem Electronic control problem Electronic control problem IMPORTANT If this type of failure occurs too often, call an approved after sales technical service. For safety reasons, the boiler will only allow 5 reignition attempts in 15 minutes (pressing of the RESET button). After the fifth attempt, the boiler goes into safety shutdown mode E 99. This is therefore not a problem in the case of sporadic or isolated stoppages. SAFETY SHUTDOWN “E” In the event of a safety shutdown, indicated by display of the letter E followed by a number, there is no need to take action. The boiler will automatically attempt to reset and restart. If this does not occur, call a qualified technician. Switch off the boiler as described in the previous paragraph, close the gas tap and move the external electrical supply switch to the OFF position. Antilocking of pump and three-way valve To prevent locking of the components, the appliance performs a self-test every 24 hours: the pump starts up for 3 seconds and the diverting valve is operated. 7. FILLING INSTRUCTIONS A method for initially filling the system and replacing lost water during servicing and initial filling (in accordance with current Water Regulations), is provided as an integral part of the connection kit (see Fig. 3.1). To fill the system and replace lost water it is necessary to proceed as follows: - Switch off the power to the boiler; - Ensure that the flexible hose is connected to both the cold water inlet connection and the C.H. flow connection; - Open the black lever on the valve for the C.H. flow connection and slowly open the black handle on the valve for the cold water inlet until water is heard passing through the valves; - Once the pressure gauge 37 (Fig. 2.1) reads between 1 and 1.5 bar close the levers on both the cold water connection and the C.H. flow connection - Switch the power to the boiler back on. FIG. 7.1 NOTE: THE FLEXIBLE HOSE MUST BE REMOVED ONCE THE SYSTEM HAS BEEN FILLED. 7
