Line Pressure Boost Connued...
From the picture on the previous page, “AUTO” is the seng on line 2 for normal operaon. In “AUTO”
mode, whenever a brew valve or water control valve is acvated, the power board will also trigger a pump
relay to run a line pressure generang pump and motor package. If this is set to “OFF”, the line boost motor
will not acvate. The “ON” seng 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™ tesng method is as follows:
Using a boomless portalter, dose out 16-18 grams of coee 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 ow-
ing through the puck while pouring a 25 second, 2 ounce shot. This process is repeated a minimum of 3
mes per brew group in order to get the most accurate readings. The dierence between the measured
puck temperature and the raw tank temperature becomes the brew oset
This oset should not be altered without thoroughly tesng the puck temperature, as menoned above.
Synesso keeps a log of the factory osets for each machine. Contact Synesso Technical Support if you need
to obtain the original factory-determined oset values.
