DESCRIPTION
The Automatic Computer Drying Control is used to manage the drying and cooling
cycles of one clothes dryer. The operator has the flexibility to select either automatic or
timed drying and either automatic or timed cooling. When automatic is selected, the
drying cycle will be terminated when the clothes are dry. A dryness sensor "feels" the
clothes and signals the control when they are dry. In the timed mode, the operator sets
the time and temperature for the load.
FEATURES:
• Automatic/Timed drying selection.
• Automatic/Timed cooling selection.
• Fabric selection (in automatic mode only).
• LED display of cycle time.
• Drying temperature range of 100° F - 195° F (Timed mode only).
• Drying time range of 0-60 minutes (Timed mode only).
• Cooling time range of 0-60 minutes (Timed mode only).
• Repeat Last Cycle feature.
• Safety tumble cycle.
• Reversing/Non-reversing selection (option).
• Power off after 30 minutes of non-use.

#7 SFTY-EN. The switch enables the “safety tumble” feature. To disable,
position this switch in the OFF position.
#6 6-ADD. Used in conjunction with the HEAVY fabric selection. When
switched to the “+ 6” position, an additional 6 minutes of drying time will
be added to the cycle when HEAVY has been selected. This is to
compensate for “hard to dry” loads or mixed loads.
#5 REPEAT S/E. This switch works in conjunction with the REPEAT LAST
CYCLE button. The parameters (mode, time, temperature) of the cycle will
be stored either at the START or the END of the cycle based on this switch
setting. The parameters that are stored will be used by the control when
the REPEAT LAST CYCLE button is pressed prior to starting a drying
cycle.
#4 2 DEG. Adds 2 Degrees to the differential temperature.
#3 5 DEG. Adds 5 Degrees to the differential temperature.
#2 10 DEG. Adds 10 Degrees to the differential temperature.
#1 10 DEG. Adds 10 Degrees to the differential temperature.
NOTE: The differential temperature is part of the heating logic. The heat turns off
when the temperature in the dryer reaches the temperature set for the
drying cycle. The temperature has to drop a set number of degrees below
the drying temperature before the heat will turn on. The difference
between the cycle temperature and the temperature to turn the heat on is
called the differential temperature. This control allows the differential to
be set between 5 and 25 degrees. The control “sums” the values set on the
switches but will not go lower than 5 nor greater than 25. If the sum is less
than 5 the control will default to 5. If the sum is greater than 25, the
control will default to 25.

Thermistor Calibration
To verify the calibration of the thermistor circuit, proceed as follows:
1. Disconnect the thermistor leads going to the circuit board.
2. Short the terminals at JP5 (thermistor calibration pins).
3. Press the “up arrow” and the “down arrow” keys to display the temperature.
4. The temperature should read 158 ° F.
5. If not 158 ° F, adjust the thermistor calibration potentiometer until the display reads
158 ° F.
6. Remove the jumper from the thermistor calibration pins.
7. Connect the thermistor leads to the circuit board.
Reversing Dwell Time
This potentiometer is used to set the dwell time when the dryer has the reversing option. The
dwell is the time from when the motor turns off to when it turns on again in the opposite
direction. Turning the knob counter-clockwise increases the dwell time and turning it clockwise
decreases the dwell time.
Computer Reset
Push this button if the control “locks up”. Pushing this button will reset the control.
120/230 Switch
This switch must be switched to the correct input voltage for the control to work. Applying 230
V when switched to the 120 V position will blow fuses on the circuit board.
Alarm Relay
A socket has been included to add a relay for an alarm to signal the end of the cycle. The
ALARM 1 and ALARM 2 terminals connect to the contacts of the relay. The relay energizes at
the end of the cycle and stays energized until either the door is opened or the dryer is turned
off.

DRYING TEMPERATURE. In AUTO drying mode, pressing and holding this
button will show in the display the temperature (in Deg F) associated with the
fabric selection. In TIMED mode, pressing and holding this button will show in
the display the current temperature for the drying cycle. In the TIMED mode
only, the temperature can be changed by pressing and holding the DRYING
TEMPERATURE button and using the “up arrow” or “down arrow” buttons.
DRYING TIME. In AUTO drying mode, pressing and holding this button will
show in the display “-A-”. This indicates that the automatic drying cycle has
been selected. In TIMED mode, pressing and holding this button will show in
the display the current time (in minutes) set for the drying cycle. In the TIMED
mode only, the drying time can be changed by pressing and holding the DRYING
TIME button and using the “up arrow” or “down arrow” buttons.
COOLING TIME. In AUTO cooling mode, pressing and holding this button
will show in the display “-A-”. This indicates that the automatic cooling cycle
has been selected. In TIMED mode, pressing and holding this button will show
in the display the current time (in minutes) set for the cooling cycle. In the
TIMED mode only, the cooling time can be changed by pressing and holding the
COOLING TIME button and using the “up arrow” or “down arrow” buttons.
“UP” AND “DOWN”. These two buttons are used in conjunction with the
DRYING TEMPERATURE, DRYING TIME, and COOLING TIME buttons to
change the value of those parameters. Pressing and releasing the button will
step the value one unit at a time (slowly for the first 5 seconds and then
rapidly). Pressing and holding both buttons will show the actual temperature in
the dryer.
REPEAT LAST CYCLE. Pressing this button before starting the drying cycle
will reset all of the parameters (mode, time and temperature) from the last cycle
run. To start a new cycle, press the REPEAT LAST CYCLE button and then
START.
NON-REVERSING/REVERSING (option). Pressing this button “toggles”
between NON-REVERSING and REVERSING.
Safety Tumble
At the end of the cycle the control goes into the “Safety Tumble” mode. “-S-” will
flash in the display. If the door of the dryer is not opened in 2 minutes or the
control is not turned off, the dryer will start running in cooling for 30 minutes to
prevent wrinkles from being set in the goods.

DETAILS OF OPERATION (cont’d)
Power Failure
If there is a power failure that lasts longer than 5 seconds, the control will
temporarily halt the cycle and flash “_PF” in the display. To restart the cycle,
push ON and the START. To terminate the cycle, push OFF/STOP. For power
failures less than 24 hours, the cycle parameter will be remembered. When the
power failure is longer than 24 hours, all cycle parameters will be lost and must
be re-entered.
Thermistor Failure
If the thermistor (temperature sensor) should fail, the control will halt the cycle
and flash “FFF” in the display. The dryer should not be restarted until the
thermistor is replaced.
Automatic Power Down
If a cycle is not run for 30 minutes, the control will automatically turn itself off.
Push ON to power up the control.
Dryness Sensor
When in the AUTO drying mode, the length of the cycle is controlled by a
dryness sensor. The sensor works on a “capacitor charge time” principle. The
electronic circuit looks at the charge on the capacitor in the dryness circuit.
When the capacitor is connected to the dryness probe that is located in the
center of the basket. Wet goods hitting the probe will “discharge” the capacitor
or prevent it from reaching full charge. As the goods dry, they have less effect on
discharging the capacitor until finally it is fully charged ending the drying cycle.
The time to charge the capacitor with no load in the dryer is listed below:
Charge Time (in minutes)
HEAVY 11.5
COTTON 5.5
PERMANENT PRESS 5.5
DELICATE 5.5
Automatic Cooling
When in the AUTO cooling mode, the cycle will end when the temperature goes
below 135° F.
