S1 Vivaldi II Owner’s ManualPage 134.11.2 Offset Temperature AdjustmentWhat Does Temperature Offset Do? / How Do I Use it?The Vivaldi group design exhibits a temperature drop between where the group boilertemperature probe is located and where the hot water exits the group. Consequently, thetemperature setting shown by the temperature lamps on the front panel may differ from thewater temperature at the group. Ideally, most users would prefer that the temperatureindicated by the temperate lamps exactly matches the water temperature exiting the group.LaSpaziale has partially accounted for this in its basic design. However, there are too manymachine to machine electrical and mechanical variances for this to be completely effective.That’s where the temperature offset comes in. The programmable temperature offset allowsa user with accurate group temperature measuring equipment to enter an offset in the rangeof ±8˚C (for extended offset option or 0 to -8˚C for standard offset option) in order to allowtheir machines temperature lamps to exactly match the water temperature exiting the group.Those purchasing new machines from Chris Coffee Service have had the temperature offsetprofessionally programmed used a Scace device. However, for those obtaining theexpanded offset capability via an upgrade, it is recommended that you note the current offsetprior to upgrading and then duplicate that offset using the instructions below. If you do notknow how to tell what your current offset is, you can find out by entering the temperatureoffset mode and then following instructions in paragraph 4.11.2.To Which Machines Do These Instructions Apply?Instructions are given in the two sections below both. This first is for machines with theoriginal offset adjustment. The section that follows is for machines with the extendedtemperature offset adjustment. In general if you purchased a new VII from Chris Coffee after7/1/2008 or if you know that you upgraded your older machine after that date, then theextended offset instructions should apply.If you are unsure, try both methods outlined below. Only one will work and then you’ll knowwhich version you have.4.11.2.1 Standard Temperature Offset AdjustmentWith the machine in Standby (only ON/STBY green lamp blinking), press the BOILER buttonuntil the green ON/STBY lamp and the red BOILER lamp are blinking (about 10 seconds).If the Offset = 0ºC, then no other lamps are lit. Assuming a start with Offset = 0ºC , eachpress of the BOILER button, changes the offset by -1ºC and lights an additional lamp startingwith the 91ºC lamp and going up through the ECON lamp. Once all eight offset lamps are lit,an additional press of the BOILER button cycles back to 0ºC offset.To exit the Offset mode, press ON/OFF (machine in Standby – ON/STBY blinking). Whenentering the Offset mode the next time, the last stored value is displayed.See table below:
