MOLTIO 04 OPERATING LOGIC

5/9

An NTC is used as a temperature sensor; in the event of overheating this reduces boiler element

power consumption.

The electronic system detects the current boiler temperature from the drop in voltage of the

sensor and adjusts it accordingly.

Heating element values and corresponding temperatures

: see table.

The gear motor is powered by a direct cur-

rent motor that engages with the smaller

double toothed wheel using a worm screw.

The unit is mounted on the axle of the large

gear wheel and when a coffee is requested, it

moves from the standby position to the dis-

pensing position, and then back to the stand-

by position again.

- Standby position: 1

- Dispensing position: 2
