- It is necessary to take into consideration that the thermometers on the group head usually indicate 2-3 degrees more than the temperature delivered by the brewing group.
As you can see in this video, only in some cases the temperature detected by the thermometer on the group aligns with the temperature of the thermofilter:
• thermometer, thermofil...
In order to make most accurate checks you need to use thermofilters.
Furthermore, please note that the thermometers on the group offer good indications on the condition of the brewing group, however cheaper thermofilters can have a higher tolerance in the detected value. (some thermometers cost 50 euro, while other 600 euro)
MaraX has an overheat phase, between 4 and 20 minutes after the coffee extraction.
During this time the water temperature in the coffee exchanger rises to heat the group, but then it has to lower to stabilize the syphonic heating at the value selected by the user.
So in case you erogate more coffees one after the other one, we recommend you to proceed with a new coffee shot within 4 minutes after the last coffee shot, in order to avoid to brew coffee during the overheat phase.
After these 20 minutes you will see that the temperature shown by the thermometer on the group in going to decrease until it stabilizes again.
If you want to dispense in the overheat phase, it is advisable to purge for 6 to 10 seconds before starting to dispense, as this introduces cold water into the heat exchanger and quickly lowers the temperature of the water dispensed.
Bisogna tenere in considerazione che I termometri sul Gruppo solitamente indicano 2-3 gradi più di quanto erogato dal Gruppo
Come si vede in questo video, solo in alcuni casi la temperature rilevata dal termometro sul Gruppo si allinea con la temperature del termofiltro.
• thermometer, thermofil...
per fare delle misurazioni più accurate bisogna utilizzare dei termofiltri.
A parte questo I termometri sul Gruppo offrono delle buone indicazioni sulla condizione del Gruppo erogatore, ma bisogna tenere conto della tolleranza di uno strumento da 50 euro contro un termofiltro da 600.
MaraX ha una fase di overheat, questa solitamente avviene tra’ il 4° e il 20° minuto dopo l’estrazione del caffè.
In questo tempo la temperatura dell’acqua nello scambiatore caffè sale di temperatura per riscaldare il Gruppo, ma poi deve riscendere per stabilizzare il riscaldamento sifonico al valore selezionato dal cliente.
Quindi nel caso in cui sia richiesto di eseguire più caffè in serie è consigliato di farli entro 4 minuti dal precedente, questo per evitare di erogare il caffè nella fase di overheat.
Trascorsi i 20 minuti si potrà vedere la temperatura visualizzata dal termometro sul Gruppo scendere fino a stabilizzarsi nuovamente.
Nel caso in cui si voglia erogare nella fase di overheat, è consigliabile di fare un purge di 6-10 secondi prima di iniziare ad erogare, così facendo si immette acqua fredda nello scambiatore e si abbassa velocemente la temperatura dell'acqua erogata.
Can you give us an update so far? It seems the SCACE is more accurate and respond faster. But the DVG TechUp has other basket size like 54mm for Della Corte as well while SCACE is for e61 only.
Hello, I'd like to ask about overheating phase. You wrote that "MaraX has an overheat phase, between 4 and 20 minutes after the coffee erogation". So what then should we do if we want to brew coffee in this time, let's say 15 min after erogation? Is just water flush like in normal HX sufficient? Also, what if you do multiple espresso during 20 min?
I‘d be interested in your answer to this question as well.
Hi, I've a question. I installed a temperature sensor like in the video with your laptop to watch temperature. If I pull the first shot after complete heating up the machine, everything is fine. But if I'm doing the second shot direktly after the first one, the temperature goes from 92 degree to 102. And that's to hot and the coffee is getting bitter. So how is it possible to get at least two shots? I want to drink coffee together and not one person and the second after 15 minutes. What I'm doing wrong, nor how could I adapt this?
Looking forward hearing from you.
Great Video.
I have the Lelit Bianca and I'm very satisfied. I have a question: The offset between the temperature input on the display and the water temperature on the brewing head is 10°C (Factory settings). Some owners of the Bianca have changed this offset to 13° because they measured themselves with a scace 2. They set 95° C at the display and measured only 92°C water temperature. What do you think about this?
Can you also use the scace 2 to measured the Lelit Bianca with an offset of 10°? That would be great.
Thanks
i have to test Bianca with the scace 2 and the termometer on the grouphead, but i think 13 is a good value especially in winter.
Hello, we’re you able to take the measurements on the Lelit Bianca with the scace? Thanks
Hello. Very good idea to compare the to Measuring devices. Where did you buy the scace 2 ? do you have a link ?

Thank you
Es normal que suceda en mi termémetro de grupo que al activar la palanca de erogación suba 4 ó 5 grados la temperatura? me parece excesivo, esto sucede en los 3 rangos de temperatura del botón inferior.

Good comparison. One thing, the Scace uses a type T thermocouple, you have your meter set on K.
yes
Hello, the question is: why?
Im a noob in temperatur messure. I also have a Tech Up Device here and i would messure my bianca v3.
Test with T or K setting?
@@crackacc Hello, I was hoping Lelit insider would explain why he uses the K setting when using both the Scace and Tech Up devices. Both device use a T type thermocouple, so the meter should be set to T setting. When using my Scace on T setting, the temperature is 4 degrees Celsius lower than the K setting.
@Alasdair R my techup device shows 2degrees difference between t and k setting. k higher…What a machine do you use?
@@crackacc Thanks for sharing your results. I am using a Linea Mini. I ended up putting the Scace over boiling water and recorded the results. On K setting, i got 104 degrees C. On T setting, i got 100 degrees C. I should note I am at sea level.
What is your conclusion about your test?
i have to do more tests, with other struments to determinate the winner

Hi Lelit Insider, i did a Google translate of "
MaraX ha una fase di overheat, questa solitamente avviene tra’ il 4° e il 15° minuto dopo l’estrazione del caffe’
In questo tempo la temperatura dell’acqua nello scambiatore caffe’ sale di temperatura per riscaldare il Gruppo, ma poi deve riscendere per stabilizzare il riscaldamento sifonico al valore selezionato dal cliente.
Quindi nel caso in cui sia rischiesto di eseguire piu’ caffe’ in serie e’ consigliato di farli entro 4 minuti dal precedente, questo per evitare di erogare il caffe’ nella fase di overheat.
Trascorsi I 15 ninuti si potra’ vedere la temperatura visualizzata dal termometro sul Gruppo scendere fino a stabilizzarsi nuovamente."
and i get "MaraX has an overheat phase, this usually occurs between the 4th and 15th minutes after the extraction of the coffee. During this time, the temperature of the water in the coffee exchanger rises in temperature to heat the Group, but then has to go down to stabilize the siphonic heating at the value selected by the customer.
Therefore, in the event that it is required to run more coffee in series, it is recommended to make them within 4 minutes of the previous one, to avoid dispensing the coffee in the overheat phase.
After 15 minutes, you will be able to see the temperature displayed by the thermometer on the Group go down until it stabilizes again."
Does this mean after 4 minutes of each shot, the overheating will happened? i don't think so right?
Or you mean after we make many cups with MaraX and then because water is low, so new cool water from tank will flow in and then the overheat will start and it last from the 4th to 15th minute from the time the cool water came in?
in marax, the more coffee made, the more cold water enters the exchanger.
This prevents overheating,
if only one coffee is made, overheat can occur,
in this phase the heating element is switched off precisely to counteract this phenomenon
The test #1 is not correct because you throw a cold portafilter into the group head and run the test right away.
The test #2 is not correct because of the same first error plus you did not let the boiler reheat the boiler (boiler light is lit). Result = nothing proven.
Quanto costa il tech up?
noi non lo vendiamo, bisogna cercare un rivenditore
@@lelitinsider2977 grazie, come ho cercato costa circa 590€
Saluti d'atene amico
So each of those thermofilters are between $600-$700? That’s crazy! That’s half the price of my ECM Classika. There has to be a far cheaper DIY version.

unfortunately yes, it is too expensive
