The water recedes back from the infusion element towards the third outlet because of the
pressure it was submitted to by the pump in the infusion process.
I1. 3rd outlet open
I2. Infusion element joined to atmospheric pressure
I3. Boiler water closed

Temperature control of the water in the boiler is done with a PTC100. Default Temperature
from factory is programmed to 85ºC, it can be programmed up to 96ºC.
It must be taken into account that, depending on the altitude at which the
machine is installed, the water can boil at a temperature below 100ºC.
