2.3 OPERATION MODES
2.3.1 Prime Mode:
After turning on or pressing PRIME button the machine goes into Prime Mode.
This is a stand-by mode when the water is prepared for final dispense.
The tank will fill to the middle level probe (PRIME FILL) and heat up (PRIME HEAT) to the
preset temperature (
Prime temp in calibration). Once the temperature gets above (Prime
temp - 1°C) the display will show PRIME READY message and the BOOST button will be
enabled. From this moment machine will be taking water in short bursts until it fills all the
tank (heat fill cycle) and the message PRIME READY FULL will appear.
NOTE: The user may use water even before the tank is full. The amount of water available
will be in the range between 2 and 6 litres.
Prime Mode logic is based on thermostatic principal
– the water accuracy is around ±2°C
from the set point.

To Empty the Tank.
In the Prime Mode the tank maybe emptied by Pressing and Holding the PRIME button for
>5 seconds. This will switch on the Pump
– Using the Dial on the FONT the tank may be
emptied. To exit this mode press the PRIME button.
Note: LARGE TANK setting will empty approx. 8 Litres.
2.3.2 Boost Mode:
In Boost Mode the user sets the desired temperature. This is done by pressing BOOST to
turn on the pump and then repeatedly pressing the BOOST button to increase the SET
TEMP (shown on the screen) in 0.1°C steps (holding down the button will quickly cycle it
upwards). The set-up temperature range is between
Prime temp and Max temp .
After setting up the machine, it will start to heat to the desired temperature and will maintain
it within ±0.2°C. The SET TEMP may be increased at any time by pressing the BOOST
button. Pressing PRIME button will make the machine go back to Prime Mode and reset the
SET TEMP back to
Prime temp . The machine will refill when in Prime mode and so take time
to heat back up again.
The Boost Mode is based on the Advanced Proportional Logic (APL
ogic™) control algorithm
that controls the heating rate to avoid temperature overshoots..
