PID-Temperature control
The PID-temperature control regulates the temperature of all boilers, meaning that the boiler temperatures can be
adjusted and controlled separately. You have the option to extract the coffee at different temperatures. PID stands
for ‘proportional-integral-derivative’. Temperature plays a key role when brewing coffee.
