LCC Basic user functions
Actual brew and steam temperature
The Lelit Elizabeth canactually be set to show the target brew temperature rather than the actual brew
temperature. Itwould be unusual to set the machine like this in the advanced settings, howeverif it is
set that way, Lelit give you the option of viewing actual brew temperature. If the machine is already set
to show actual brew temperature the firstpress of the +button will appearto have no effect. The
second press of the + button shows the steam boiler temperature
After a few seconds of no button press, the display returns toit's "home Screen" where the actual or
preset brew temperature will be displayed along with the status of the steam boiler.
Home Screen
The display with either display brew temperature, orbrew temperature with an eco symbol if the steam
boiler is off.
Other functions
These are selected by pressingthe minus (-) button.

This button can scroll to various parameters, when you see a parameteryou want to change, press the
plus button to select it, then the - and + buttons will change the value.
If no button is pressed for a few seconds the machine will return tothe home screen.

Programming automatic shot times
The Lelit Elizabeth canhave shot times programmedto each button. These allow forthe espresso shot
to end when the program time has been reached. e.g. if you program 30 seconds, the shot will stop 30
seconds afterthe button is pressed. Any preinfusion times are included in this time. e.g. a 10 second

preinfusionwith ashot time programmed of 30s will still take 30s in total 10 seconds of which will be
preinfusion.
For button 2 the procedure is similar.

Setting Preinfusion times button 1
Preinfusion times can be set here. This is the total time for preinfusion. It comprises a pump on time (set
in the advanced menu) which becomes part of the preinfusion time. e.g. if the advanced menu for
preinfusion has apump on time of 3s and you set a total preinfusion time of 10 seconds. The pump will
run for the first 3s and stopfor the next 7s. Then the pump restarts to complete the shot.
Preinfusion time forms a part of any total shot time programmed.

Preinfusion for button 2
Steam On or Off
Steam can be set on and off in the menu system in the same way as any otherfunctions.

Functions accessed via buttons
Turn standby function on/off
This powers down the machine after a preset period (about 30minutes). A feature of all modern
espresso machines, partof EU Law. I don’t personally find it useful, even though the Elizabeth has a
very fast warm up of about 15 –17 minutes. The standby function is toggled on/offby; switching the
machine on while holdingin coffee button 2.
The water button LED will be flashing if standby is on, and off, if standby is disabled.

Purge water through the group
To automatically flush a set amount of water through the group for cleaning, press the coffee1and
coffee2buttons at the same time.
Automatic Backflush routine
This performs a series of automaticbackflushes when using cleanerin a portafilter with a blind basket. I
use this to finish off a couple of manual backflushes as part of my recommended hybrid backflush
routine. Toaccess this function press the coffee1and hot water buttons at the same time.

Lelit Elizabeth Advanced LCC Settings
To access the advanced menu
Below are my recommended advanced settings for the Lelit Elizabeth LCC
Pressingthe –button scrolls through the list. Pressing the +button puts the selected value into change
mode where + & - incrementand decrementthe value. If you change a value, wait forthe value to stop
flashing and be accepted before pressing –to move to the next value.
You will probably only need to enterthe advanced menu a few times to check your settings and set up
your preferred pump on times for Steam and Bloom preinfusion. Once you have decided what you like
it's unlikely you willneed to enter the advanced settings again.
If everyou have a software update you will loseany customised settings, this may also happen if you
send the machine off to be serviced. I recommend you make a note of your preferred settings and keep
it in a safe place.
KPc = 0.2 (PIDProportionalvalue coffee boiler)
KIc = 0.07 (PID Integralvalue coffeeboiler)

KDc = 10
Bc = 30 (temperature range over which PID acts - this really doesn't matter with such a small boiler)
KPs = 2.0 (PID Proportionalvalue steam boiler I left at 2 for a stronger response in case a higher value
firmwaredefault is programmed even if 0 is used). I also want to prevent any large overshoot at max
temp settings.
KIs = 0.00 (PID Integralvalue steam boiler –not required, no benefit to changing this value)
KDs = 0.0 (PIDderivative value steam boiler –not required, no benefit to changing this value you don't
really want derivative on this boiler)
Bs = 1 (temperature range overwhich PIDacts I would have set 0 if I could to act as a full powerON/OFF
controller)
EC = 10 (this is the offsetforthe brew boiler, it allows for cooling of the brew water by the time it hits the
coffeeand displays the tested brew temperature at the coffee)
ES = 0 (I don't want an offset for steam, this way I can convert temperature to an accurate pressure)
F01 = 1 (illumination on = 1 or off = 0)
TR1 = 1 (this allows the LCC to display the actual temperaturea value of 0 means the LCC only shows the
set temperature)
TOT= not used
The Values below you can change to suit your situation and needs
Preinfusion Type - Steam, Bloom or auto
Lelit Elizabeth can perform steam pressure preinfusion and bloom preinfusion automatically selecting
the type used dependingon eitherthe on/off state of the steam boiler, orit's temperature (if it is too
low). The value of EVS controls this. If the electrovalve is enabled (on), then both types of preinfusion
are available.
Turning this electrovalveoff using asetting of 0 disables steam preinfusion and regardless of the on/off
state or temperature of the steamboiler. The machine will only perform bloompreinfusion.
