DIGISTAT OPTIMISEROPERATING CONTROLSDigistat Optimising ProgrammerThe Digistat Optimising Programmer has factory set programs for ON/OFF periods for central heatingwhich are described on the following pages.These factory installed settings can be used without any further programming.Clock SettingThe Digistat Optimising Programmer is fitted with a real-time clock, which is pre-set at the factory.You will not have to set the time.A special feature of this real-time clock is to automatically update the time during the summer/winter timechange removing the need to manually alter the clock.DaysTemperaturesee note+ or - buttons forsetting adjustmentDay indicatorFlame showswhen callingfor heatTimemodeindicatorHoliday, Manual,Auto, Day modeLeft hand button < movespointer to the left for selectionRight hand button > moves thepointer to the right, selects andaccepts changesClock modeNOTE: The temperature displayed is actual room temperature unless adjusting the + or - buttonwhen the set temperature is displayed. Once adjustment is complete and after a 5 seconddelay the display will return to the actual room temperature.General OperationWith the unit in Auto mode (the small arrow to bottom of screen will point to Auto) the temperature can bechanged for a short time by using the + or - buttons. Changing the temperature in this way will keep theProgrammer set to your new temperature until the next pre-programmed event (at which time it will revertto programmed temperature). The temperature you are setting will flash on the screen. Once temperatureis set, the unit will revert to showing the current temperature. The indicator will show on the screen if theheating is turned on.4OPER AT I NG & INSTA L L AT IONINST RUCT IONSDT10RF OPTIMISING PROGRAMMERINSTRUCTION MANUAL8 716 114 492a (08.07)
