4.11.2 Offset Temperature Adjustment
What Does Temperature Offset Do? / How Do I Use it?
The Vivaldi group design exhibits a temperature drop between where the group boiler
temperature probe is located and where the hot water exits the group. Consequently, the
temperature setting shown by the temperature lamps on the front panel may differ from the
water temperature at the group. Ideally, most users would prefer that the temperature
indicated 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 many
machine to machine electrical and mechanical variances for this to be completely effective.
That’s where the temperature offset comes in. The programmable temperature offset allows
a user with accurate group temperature measuring equipment to enter an offset in the range
of ±8˚C (for extended offset option or 0 to -8˚C for standard offset option) in order to allow
their machines temperature lamps to exactly match the water temperature exiting the group.
Those purchasing new machines from Chris Coffee Service have had the temperature offset
professionally programmed used a Scace device. However, for those obtaining the
expanded offset capability via an upgrade, it is recommended that you note the current offset
prior to upgrading and then duplicate that offset using the instructions below. If you do not
know how to tell what your current offset is, you can find out by entering the temperature
offset 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 the
original offset adjustment. The section that follows is for machines with the extended
temperature offset adjustment. In general if you purchased a new VII from Chris Coffee after
7/1/2008 or if you know that you upgraded your older machine after that date, then the
extended offset instructions should apply.
If you are unsure, try both methods outlined below. Only one will work and then you’ll know
which version you have.
4.11.2.1
Standard Temperature Offset Adjustment
With the machine in Standby (only ON/STBY green lamp blinking), press the
BOILER
button
until 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 , each
press of the
BOILER
button, changes the offset by -1ºC and lights an additional lamp starting
with 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). When
entering the Offset mode the next time, the last stored value is displayed.
