It will improve the consistency of the brewing even if you didn't tamp the coffee perfectly. The extraction timer contains three segments: pre-infusion pulse (Tp), soak (Td), and brew (Tb). Each segment can be set by user with 0.1second resolution.
When the ">" key is pressed, the controller starts the brewing sequence automatically. The pump can be stopped at any time by pressing the ">" key a second time.This feature allows you to operate the brew pump manually, with the timer as a reference. User can also bypass the timer to use switch on the machine for manual controlling the brewing process. The steam temperature is controlled by the same controller that controls the brew water temperature. To the user, the operation is the same as regular machine; no extra button is needed to press for frothing. When the steam switch is turned on, the on/off temperature of the heater is controlled to 1 degree (F or C) difference as compared with original thermostat's >10C (or 20F) difference. With this tight temperature control, you do not have to surf the temperature for frothing because the heater will kick on much sooner than the original thermostat. The on/off temperature can be adjusted by the user. The installation is completely reversible if you ever want to sell the machine or send it to service.
