Sets dead time (measured in seconds from the
beginning of every heating cycle in BOOST mode)
when software waits for the tank sensor to record
temperature change. Value depends on element
time constant and placement of the thermistor.
Setting the value too high will make temperature
swing too much in BOOST mode; setting too low
will make machine overshoot too much.
00:12
(for
both 2L
&6L,)
Sets BOOST mode time-out. Timer starts at the
beginning of the BOOST mode. Machine goes back
to PRIME mode after that time to avoid unit being
left in Boost Mode for too long.
06:00
This sets the tank volume (switching between 2
probes). LARGE is a ~6L drawoff and SMALL is a
~2L drawoff. In SMALL/2L mode the temperature
increases faster (e.g. to boost from 90 to 96C will
be quicker ). There is no difference in recovery
rates, i.e. if you take off 1Litre of water in either
mode it takes ~2min for it to heat back to 90C.
A 2L setting is typically used when you require
lower brew volumes and more varied temperatures
between brews.

To recalibrate the scale:
- empty the weighing platform,
-

- place 1kg calibration weight,
-
press BOOST button (set new value for 1kg)
WEIGHT shows live readout of the weight.
Press TIME button to accept all the settings
