DIGITAL DISPLAY
The Digital ThermoFresh
a circuit board designed to sense liquid levels & hold times. During the monitoring process, the probe sends information to the
display. The display then allows the user to monitor the liquid level and freshness (hold time) of the beverage held in the server.
HORIZONTAL BAR
Using the Digital Sight Gauge display, the liquid level in the server can be monitored by watching the horizontal bars. The
1.0 gallon display is equipped with 4 bars and the 1.5 gallon with 6 bars to represent
the level inside the dispenser. (each bar represents a quart, or one quarter of a gallon)
All four/six bars will be displayed when the server is full. When the level of the
liquid drops to a certain level, the highest bar on the display will no longer be illuminated. These bars will continue to disappear as the level inside the dispenser drops.
(See Fig. 1)
COUNT UP TIMER
The Digital display is set to count up to 4:00 hours. The display counts up in one
minute increments, flashing at 2:00 hours and continuing to flash once it reaches 4:00
hours. (See Fig. 1)
COUNTDOWN TIMER
The Digital display is set to countdown 2:00 hours. The display counts down in one minute increments, flashing at 15 minutes
and continuing to flash once it reaches 0. (See Fig. 1)
®
Server is equipped with a digital probe and display called a Digital Sight Gauge. The probe contains
FIG. 1
TIMER RESET
The display will reset to 0 when any of the following occurs:
• The liquid level in the server is increased by 1 bar for a sustained period of time. (brewing into, or adding additional liquid to
existing beverage)
• A fresh new beverage is brewed into the server.
• When the contact pins of the sensor assembly are disengaged from the display for more than 20 seconds.
DISPLAY OFF
When the sensor assembly on the server is removed or loosened for more than 20 seconds, the display on the Digital
Sight Gauge breaks contact with the pins on the surface of the server. When this happens, the outline that surrounds the
Horizontal Level Bars will flash on and off and the time disappears. This indicates that the display has been disengaged from
the probe and cannot receive data.
When the display is in place and engaged, but the server is empty, the outline surrounding the Horizontal Level Bars will
be on but not flashing and the Freshness Time will not be displayed. All other portions of the
display will not be visible. This indicates the display is engaged and ready to receive data from
the probe, but the server is empty.
The only time the display will be completely blank, is when the batteries have been removed
or have expired. (See the “Battery Replacement” section for additional information.)
FRESHNESS TIME (Countup)
This unit is factory set to count up to 2:00 hours, and begin flashing. If a reset condition
has not occurred, it will continue to flash and count up to a maximum of 4:00 hours. Flashing
notification is adjustable and can be set between 15 minutes and 3 hours 45 minutes in 15
minute increments. Setting changed by opening battery compartment and positioning rotary
switch using a small screwdriver. Settings are defined in the Flashing Notification Table.
FRESHNESS TIME (Countdown)
This unit is factory set to count down to 15 minutes, and begin flashing. If a reset condition
has not occurred, it will continue to flash and count down to 0.

LOW BATTERY INDICATOR
When the batteries in the display unit are running low, the display is also equipped with
a battery icon. The upper most bar used in monitoring liquid levels, will begin to flash in the
shape of a battery to indicate that it is time to replace the batteries. (See FIG. 1)
BATTERY REPLACEMENT
The Digital Sight Gauge display comes equipped with 4 AAA batteries. The batteries have
a use life of approximately 1 1/2 years under normal operating conditions.
NOTE: Batteries are not covered under product warranty.
To replace the batteries:
1. Remove the sensor assembly from the server.
2. Remove the two thumb screws and slide display assembly from the server.
3. Remove the two screws and cover on bottom of the display, Fig 2.
4. Replace used batteries with 4 AAA alkaline batteries.
5. Replace cover and two screws.
6. Replace display assembly and secure with two thumb screws.
SENSOR ASSEMBLY INSTALLATION
FIG. 2
Proper installation of the sensor assembly is achieved by aligning the contacts of the sensor assembly (B) with the
contacts on the back of the sight gauge (A) when the sever handle is in the fully open position. Once the sensor assembly
is engaged into the server, it is locked in place by flipping the handle over approximately 180° as shown in Fig 3.
