S1 Vivaldi II Owner’s ManualPage 17Consequently you must use the instructions provided in section 4.10.1 to set themaster temperature to 91ºC or 97ºC BEFORE using the instructions below. If this is notdone, the instructions below for entering the Extreme Temperature Set mode will workas described, but once in that mode attempting to a raise or lower the temperature hasno effect.Instructions for programming this mode AFTER setting the master temperature to 91ºC or97ºC are:• Start with the machine in Standby mode (ON/STBY light flashing).• Press and hold the Two Cup button for ~3 seconds until lights 94ºC (17) and 95ºC(18)come on indicating that the Extreme Temperature Function setting mode is active.• If you start with the master temperature set to 97ºC, each time that the Hot Waterbutton is pressed, lights 96ºC (19), 97ºC (20), and Econ (21) will switch on insuccession. Each light indicates a 1ºC increase. All three lights on = 100ºC.• If you start with the master temperature set to 91ºC, each time that the One Cupbutton is pressed, lights 93ºC (16), 92ºC (15), and 91ºC (14) will switch on insuccession. Each light indicates a 1ºC decrease. All three lights on = 88ºC.• Press the Two Cup button again to exit Extreme Temperature set mode and returnback to Standby modeNotes:When you change the temperature of the 91ºC and/or 97ºC buttons according tothe above instructions, the change only remains in effect until the temperature ischanged. For example, if you change the 91ºC selection by 3ºC to yield 88 ºC,then later change the temperature to 93C, the next time you select 91ºC, youwill get 91ºC, not 88 ºC. If you wish to obtain 88ºC again you will need to followthe above instructions to reprogram in the 3 ºC decrease.4.12 Programmable PreinfusionNote: only machines purchased or upgraded after 7/1/08 have this feature.With the machine on (ON/STBY (22) lit and not blinking), press and hold the ON/OFFbutton(27) for three seconds until the ON/STBY (22) and the current preset temperaturelamps are both blinking. Then press the BOILER button (13) for 3 seconds. The temperatureplus ECON lamps now display the current time delay between when the group water solenoidopens and when the pump is activation. This is the preinfusion time. If none of the lamps 14-21 are lit, the preinfusion time is 0 seconds which means no preinfusion. Each press of theBOILER button (13) increases preinfusion time by 1 second and lights one more lamp up to amaximum of 8 seconds when all of the temperature and ECON lamps (14-21) are lit. Whenpreinfusion is set to 8 seconds, another press of the BOILER button (13) resets thepreinfusion back to 0 seconds.
