PROGRAMMING
Menu Level 2: Brew Group 1 Offset
Line 1 indicates that you are now in the Brew Group 1 Offset screen.
Line 2 indicates the actual water temperature at the selected brew group's temperature probe as it is
maintaining your Set Temperature.
Line 3 represents the actual temperature reading of water flow through the puck.
Line 4 indicates the temperature adjustment made at the Synesso™ factory, in order to create the
exact temperature desired at the puck.
Puck Temperature on line 3 is determined at the factory, according to the standard Synesso™ testing
method. Adjustment to this setting is not recommended without thorough testing.
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
flowing through the puck while pouring a 2 ounce shot. This process is repeated a minimum of 3
times per brew group in order to get the most accurate reading.
This reading is then applied to line 3 by pressing the corresponding button.
Use the '▲' '▼' buttons to select the desired setting and then confirm the selection.
Inserting the temperature on line 3 will automatically set the line 4 offset.
The Offset on line 4 can be altered to achieve the same effect as inputting a temperature on the Puck
temperature line. Changing the offset will correspondingly alter the puck temperature. This offset point
should not be altered without thoroughly testing the puck temperature, as mentioned above.
To cycle to the next display screen press the button next to line 1.
