Digital Brew Timing - Brew time is accurate to within .1 seconds over the entire adjustment range of 30 to 360
seconds.
AutoCal Function - Allows the brew volume to be set with one brew cycle. To use feature it is best to remove the
brew basket due to the delay in cessation of the sprayhead delivery and the final drainage from the brewbasket. If
doing so place a wide mouth pitcher of suitable volume and with desired volume level indicated on pitcher below
sprayhead to capture brewed water. Brew time adjustment knob may be turned all the way up and then a brew cycle
started. During the brew cycle, as the volume approaches the correct level in the decanter, slowly rotate the dial
down until brewing stops. The timer is now set for the delivered amount of water. (As an alternate to this temporarily
replace the standard brewbasket with a basket which has had the outlet enlarged to allow the water to flow out as
fast as it comes in. Do not use this basket for brewing coffee.)
Auto Arm - Ensures that the brewer is up to temperature prior to brewing to ensure proper extraction is obtained. If
the water temperature in the tank is below the value set by the "Solid State Thermostat" on the control board when
the brew cycle is initiated the fill portion of the brew cycle is delayed. The heating light will begin to flash indicating
that the unit is in the brew mode but is not up to temperature (brewing light will also be on). The tank heater will
begin heating and when the tank reaches the preset temperature the fill portion of the brew cycle will begin. This
feature may be disabled if desired by connecting the 1 pole connector with blue wire to the mating connector with
red wire. Connectors are positioned above the fill valve. Refer to wiring diagram on page 6. The autoarm feature
may be bypassed for individual brew cycles by holding in the brew start switch for about 3 seconds. Release switch
when brew cycle starts.
Visa-Brew - Continues to flash the brewing light after the fill portion of the brew cycle has stopped alerting the user
that the brewed hot coffee has not finished draining from the brew basket. This popular feature has been enhanced
with an autocal feature similiar to the brewing autocal described above. Simply turn the adjustment dial all the way
up, start a normal brew cycle as described under the "OPERATION INSTRUCTIONS", and after the brewed coffee
has quit dripping from the basket turn the dial down just until the brewing light turns off. Visa Brew is now custom set
for your machine, filters, and coffee.
Power Save Mode - Allows you to automatically save energy when the brewer is not in use for a specified length of
time. In this mode the tank heater will be set back to 170
°
F after being idle for the selected time. To select the
timeframe before power save mode is engaged, rotate the dial on the board labeled "Run Time Before System
Shutdown" to the desired setting. If the dial is put in the off position the brewer fill be in a normal mode mode the
tank temperature will be maintained at the temperature set on the control board at all times. Starting a brew cycle
will reinitialize the timer and the set time frame starts over. If the autoarm has not been disabled the tank will be
brought up to temperature before brewing when the brew start switch is depressed.
Solid State Thermostat - Maintains temperature within 3 degrees throughout the adjustment range of 170-208
degrees. Full off position is at the extreme left of the adjustment dial. The only wear item, a remotely mounted relay,
may be replaced without disturbing the tank or re calibrating the temperature. This also allows the incorporation of
several other convenience and safety features as explained below.
Initial Tank Fill Circuit - Prevents the tank element from coming on before water level in tank has covered the
element in the tank when setting the brewer up. This acts as a backup to the unique mechanical heater control
incorporated into the brewers tank system to ensure that the tank element or its components are not damaged by
premature heatup. The fill solenoid will run until water contacts the probe in the upper expansion chamber or for up
to 6 minutes, whichever comes first. See "Tank Fill" under the "INITIAL SETUP INSTRUCTIONS" for operation.
