Control Company 4148 JUMBO REFRIGERATOR/FREEZER THERMOMETER - Manual

SPECIFICATIONS
Range:
-58.0 to 158.0 °F / -50.0 to 70.0 °C
Resolution: 0.1°
Update Rate: 10 seconds
Battery: AAA (1.5V)
Probe Supplied:
Model 4148-- Supplied with a standard probe sensor with cable. Both sensor and
cable may be immersed in liquid. Probe sensor may be mounted using the supplied
sensor holder and mounting screw.
Model 4548 & 4648-- Supplied with a bottle sensor and cable. Bottle sensor is filled
with a patented nontoxic glycol solution that is GRAS (Generally Recognized As Safe)
by the FDA (Food and Drug Administration) eliminating concerns about incidental
contact with food or drinking water. The solution filled bottle simulates the temperature
of other stored liquids. Velcro
® and a magnetic strip are provided to mount the bottle
to the inside of a refrigerator/freezer and to mount the display on the outside. The
micro-thin probe cable permits refrigerator/freezer doors to close on it.
TEMPERATURE DISPLAY MODES
Ambient Temperature Display Mode (IN): Indicated by “IN” appearing on the
display, displays the current ambient temperature and either the ambient temperature
memory (MIN/MAX) or the ambient temperature alarm limits (LO/HI).
Probe Temperature Display Mode (OUT):
Indicated by “OUT” appearing on the display, displays the current probe temperature
and either the probe temperature memory (MIN/MAX) or the probe temperature alarm
limits (LO/HI).
To change between ambient (IN) and probe (OUT) temperature display modes, press
the IN/OUT button located on the back of the unit.
To change between displaying the memory (MIN/MAX) and the alarm limits (HI/LO),
press the MODE button.
DISPLAYING °F OR °C
To display the temperature readings in Fahrenheit or Celsius, press the °C/°F button
located on the back of the unit.
MINIMUM AND MAXIMUM MEMORY
There are four points that are automatically recorded into memory:
Minimum (MIN) Ambient Temperature Achieved
Maximum (MAX) Ambient Temperature Achieved
Minimum (MIN) Probe Temperature Achieved
Maximum (MAX) Probe Temperature Achieved
All four memories are independent of each other. Minimum and maximum
temperature memories are NOT programmable. The minimum temperature recorded
into memory is the minimum temperature achieved since the last time the memory was
cleared. The maximum temperature recorded into memory is the maximum
temperature achieved since the last time the memory was cleared. The minimum and
maximum temperature memories are maintained over the period since the memory
was cleared.
Minimum and maximum memories are recorded for both ambient and probe
temperatures regardless of the display mode.
CLEARING THE PROBE (OUT) TEMPERATURE MEMORY
1. Select the Probe Temperature Display Mode by pressing the IN/OUT button located
on the back of the unit until “OUT” appears on the display.
2. Press the MODE button until “MIN” and “MAX” appears on the display.
3. Press the MIN-RESET button to clear the minimum temperature memory. The
display will show “88.8” under MIN and will then display the new minimum
temperature memory.
4. Press the MAX-RESET button to clear the maximum temperature memory. The
display will show “88.8” under MAX and will then display the new maximum
temperature memory.
CLEARING THE AMBIENT (IN) TEMPERATURE MEMORY
1. Select the Ambient Temperature Display Mode by pressing the IN/OUT button
located on the back of the unit until “IN” appears on the display.
2. Press the MODE button until “MIN” and “MAX” appears on the display.
3. Press the MIN-RESET button to clear the minimum temperature memory. The
display will show “88.8” under MIN and will then display the new minimum
temperature memory.
4. Press the MAX-RESET button to clear the maximum temperature memory. The
display will show “88.8” under MAX and will then display the new maximum
temperature memory.
ALARMS
Both ambient (IN) and probe (OUT) temperature alarm limits may be set in 1°
increments.
With the alarm enabled (֠), the unit will sound an alarm when the temperature being
displayed is outside the alarm limits that have been set for that display mode (equal to
or lower than the low alarm set point, or equal to or greater than the high alarm set
point). Example: If the unit is displaying the ambient temperature (IN) and the probe
temperature (OUT) is outside the probe temperature alarm limits, no alarm will sound.
SETTING PROBE (OUT) TEMPERATURE ALARM LIMITS
1. Select the Probe Temperature Display Mode by pressing the IN/OUT button
located on the back of the unit until “OUT” appears on the display.
2. Press MODE button until “LO” and “HI” appears.
3. To set the low temperature alarm limit (LO), press the LO ALM SET button to
advance the display until the desired low temperature is displayed. Press and hold
the LO ALM SET button to rapidly advance the display.
4. To set the high temperature alarm limit (HI), press the HI ALM SET button to
advance the display until the desired high temperature is displayed. Press and hold
the HI ALM SET button to rapidly advance the display.
SETTING AMBIENT (IN) TEMPERATURE ALARM LIMITS
1. Select the Ambient Temperature Display Mode by pressing the IN/OUT button
located on the back of the unit until “IN” appears on the display.
2. Press MODE button until “LO” and “HI” appears.
3. To set the low temperature alarm limit (LO), press the LO ALM SET button to
advance the display until the desired low temperature is displayed. Press and hold
the LO ALM SET button to rapidly advance the display.
4. To set the high temperature alarm limit (HI), press the HI ALM SET button to
advance the display until the desired high temperature is displayed. Press and
hold the HI ALM SET button to rapidly advance the display.
ENABLE/DISABLE ALARMS
To enable the alarm to sound when the temperature being displayed is outside the
alarm limits, press the ֠ button located on the back of the unit until “֠” appears on
the display. Each successive press of the ֠ button will enable (֠) or disable the
alarm.
ALARM SOUNDING
With the alarm enabled (֠), the unit will sound an alarm when the temperature being
displayed is outside the alarm limits that have been set for that display mode (equal to
or lower than the low alarm set point, or equal to or greater than the high alarm set
point). If the alarm is sounding based on the low alarm limit, “LO” will flash on the
display. If the alarm is sounding based on the high alarm limit, “HI” will flash on the
display.
The unit will continue to alarm and flash the corresponding “LO” or “HI” until the
temperature being displayed is within the alarm limits. Once the temperature being
displayed is within the alarm limits, the alarm will stop sounding and the
corresponding “LO” or “HI” will no longer flash.
To silence an alarm manually, press any button. When manually silenced, the
corresponding “LO” or “HI” will continue to flash on the display until the temperature is
within the alarm limits.
When enabled (֠), the alarm will only sound if the temperature being displayed is
outside the alarm limits that have been set for that display mode (IN or OUT).
Example: If the unit is displaying ambient temperature (IN) and the probe temperature
(OUT) is outside the probe temperature alarm limits, no alarm will sound.
RESET BUTTON
The RESET button located on the back of the unit may be used to simultaneously
reset the memory and alarm limits for both the ambient (IN) and probe (OUT) sensor.
To reset the unit, press the RESET button.
When the reset button in pressed, the following will occur:
● The display will show all segments for approximately 5 seconds.
● The ambient (IN) and probe (OUT) minimum/maximum memory will be cleared.
● The ambient (IN) and probe (OUT) alarm limits will be returned to the factory
default value of 10°C (LO) and 30°C (HI).
● The unit will display the ambient (IN) temperature in °C.
