REFILL - Range: 0 to 155

This function allows the operator to adjust the

sensitivity of the reﬁ ll circuit. This is mainly a trouble-

tions can have different conductivities. By adjusting

the sensitivity of the reﬁ ll circuit, this will allow the

brewer to operate under various water conditions.

SET READY - Range: 185˚F (85˚C) to 203˚F (95˚C)

This function allows the operator to set the mini-

mum temperature allowable to start a brew cycle. The

range can be from 185˚F (85˚C) to within 2˚F (-1.7°C)

of the SET TEMP. The water must be at the SET READY

temperature or higher for the display to indicate READY

TO BREW. If brew lockout is enabled, the brewing pro-

cess will not start below this READY temperature.

NOTE: The upper limit for SET READY temperature

is 2˚F (-1.7°C) less than the water temperature (SET

TEMP) setting.

the internal controller how fast the water is ﬂ owing.

The unit of measure is ounces per minute (Oz/M).
