CAUTION!! In the United Kingdom installation, start-up, adjustments and maintenance must be performed by a CORGI registered installer in accordance with the installation standards currently in effect, as well as with any and all local health and safety standards i.e. CORGI. 3. OPERATING INSTRUCTIONS O In the Republic of Ireland the installation, and initial start-up of the appliance must be carried out by a Competent Person in accordance with the current edition of I.S.
Adjusting the heating It is possible to set the temperature of the Central Heating system by adjusting the knob “C”. By positioning the indicator somewhere between 1 and 6, a temperature may be obtained which varies from approximately 38˚C to about 82˚C. The water temperature in the primary circuit is shown on the display. M Start-up Procedure Before starting the boiler, check the following: - The water pressure on the pressure gauge “F” is between 1 and 1.
Note: If the “COMFORT” function is on during the pump overrun period, it will be temporarily deactivated. The yellow L.E.D. “G” will remain on to indicate that the boiler will resume the “COMFORT” mode once the pump overrun period is complete. Periodic operation of the appliance will occur regardless of demand on the boiler. This function is normal operation. The COMFORT mode will automatically de-activate in low water usage periods i.e. overnight. Turning on a tap will re-activate the function.
Shutdown Due to Ignition Failure This anomaly is indicated by “A01” on the display. To reset the boiler, press and then release the reset button . At this point, the electronic ignition system will attempt to light the burner again. Should the boiler fail to ignite a second time, check that the external gas cock is open. If the problem persists, contact an Authorised Service Centre. 4. USEFUL INFORMATION Shutdown Due to Overheating This anomaly is indicated by “A 03” on the display.
5. TIME CLOCK NOTE: the time clock is for central heating control only. The time clock is provided with 96 switches, called riders, each of which covers a time interval of 15 minutes (four per hour). When a rider is switched from the inside (off setting) to the outside of the clock border (on setting), the circuit is closed (switch on) for a period of 15 minutes and then the boiler starts if the room thermostat (if installed) or the heating thermostat require heat (heating function on).
Changing the programmed switching times Press the “Prog” key repeatedly until the switching time you want to change is displayed. You can now enter the new data. See point “Entering the switching times”. Notes on storing switching times: If you end your entry of the switching times by pressing the “Prog” key, then the switching time you have entered will be stored and the next memory location displayed.
