Program unit

Description

The program unit is electronic and comprises a

circuit board containing microprocessor, pro-

gram memory, current regulating circuits, tem-

perature and level control, etc.

The program unit receives its power from a se-

parate voltage unit.

The program unit receives information from the

temperature sensor, door lock and level swit-

ches. There is also a serial interface to the motor

control.

The program unit controls the water and drain

valves and the heating via the I/O board, door

closing/opening via a drum module and the mo-

tor via the motor control.
