PROGRAMMING
Line Pressure Boost Continued...
From the picture on the previous page, “ AUTO ” is the setting on line 2 for normal operation. In “ AUTO ”
mode, whenever a brew valve or water control valve is activated, the power board will also trigger a pump
relay to run a line pressure generating pump and motor package. If this is set to
“ OFF ”, the line boost motor
will not activate. The “ ON ” setting will run the boost motor constantly. This is factory set to “ OFF ” to protect
the boost pump from running without water.

Line 2 indicates the measured water temperature at the selected brew group ’ s temperature probe.
Line 3 indicates the temperature adjustment made at the Synesso ™ factory, in order to match the measured
temperature with the temperature desired inside the puck.
The Synesso ™ testing method is as follows:
Using a bottomless portafilter, dose out 16 - 18 grams of coffee into a 14 gram basket with a thermal probe
inserted 1/8th of an inch from the surface and in the middle of the puck, packing and tamping the grounds in
the basket as usual.
The thermal probe is then wired to a FLUKE thermometer to relay the actual temperature of the water flow-
ing through the puck while pouring a 25 second, 2 ounce shot. This process is repeated a minimum of 3
times per brew group in order to get the most accurate readings. The difference between the measured
puck temperature and the raw tank temperature becomes the brew offset
This offset should not be altered without thoroughly testing the puck temperature, as mentioned above.
Synesso keeps a log of the factory offsets for each machine. Contact Synesso Technical Support if you need
to obtain the original factory
- determined offset values.
For more information on factory offsets, see page 70. To cycle to the next display screen, press the down
