1 Introduction and Features
Intelligent Controller IC was designed by American Panel Corporation to control various walk-in door devices and to
monitor the temperature of the walk-in cabinet.
IC features:
• Temperature monitoring
• High and low temperature alarm with on-board buzzer and alarm time delay
• Door frame heater and window heater control
• Electronically controlled light switch with light On indicator
• Automatic light off
• External switch connection for CAL-OSHA back-to-back light control (Optional)
• Adaptive setting
1.1 Temperature Monitoring
IC monitors the walk-in cabinet temperature via a probe mounted in the warmest part of the cabinet which is near the
door. The alarm delay will ensure that the alarm does not go off during normal door openings.
For an accurate air temperature reading do not restrict the airow over the temperature probe. To monitor the air
temperature at a different location an extended temperature probe is available for purchase.
1.2 Temperature Alarms
If the temperature inside the walk-in cabinet goes above the high alarm threshold or below the low alarm threshold,
the temperature reading on the display will blink indicating that the alarm time delay has been triggered. If the
temperature does not return to normal limits within the delay time, the buzzer will go off and the display will show the
alarm message “AH” alternating with the temperature reading. The buzzer can be silenced by pressing the alarm
mute button.
The alarm’s set points and delay times are fully programmable to user’s needs.
Default set points:
High Alarm Trigger Point
(AH)
Low Alarm Trigger Point
(AL)

(AD)

1.3 Door Frame Heater and Window Heater Control
IC controller switches on the door frame heater and the window heater (if so equipped) when the air temperature
drops below the preset threshold of 45oF and then cycle them on and off based on a time cycle. On coolers, by
default, the heaters stay on for 35% of a 6-minute cycle and then will stay off for 65%, the cycle will repeat. On
freezers, by default, controller keeps the heaters on until the temperature of the cabinet goes above 45˚F. The alarm’s
set points and delay times are fully programmable to user’s needs.
Default set points:
Heaters On (Pr) Heaters Off Heaters Switched On Below Temp:
(tP)
Cooler 30% of 6-minute cycle 65% of 6-minute cycle
45˚FFreezer 100% of 6-minute cycle 0% of 6-minute cycle
Beer Cooler 65% of a 6-minute cycle 35% of a 6-minute cycle
1.4 Electronically Controlled Light Switch and Automatic Light Off
The cabinet light can be switched on and off from the IC controller. The integrated light button is equipped with an
LED light to display the ON/OFF status of the light.
The Automatic Light Off feature of IC enables the user to save energy. The amount of time the light will stay on can
be set from 1 minute to 60 minutes or can be set for manual shut off only. As default, the automatic light off feature is
disabled.
Back-to-back light control is provided as an optional feature.

IC Controller Operations Manual
3 Parameter Programming
On powering up, IC will run through a procedure to adjust its settings based on the type of room it is installed within,
user input is not required. The procedure may take up to 12 hours of continuous operation, during this time the
controller will not display any temperature alarm. The user may change any of the default settings.
Note: During the programming steps, any delay longer than one minute before pushing the next
button will cause the controller to revert to the normal operation state. To avoid this, the following
instructions should be carefully reviewed, and the desired settings should be determined before
proceeding.
The instructions below contain screens with the exact messages displayed by the controller during the programming
procedure. Follow the notes located to the left of these screens.
Press the MENU button.
The display will show:
Enter access code 055
Use the UP or DOWN button to change the blinking character to the correct number and press ENTER to conrm.
High Air Alarm Setting
The display will alternate between and the value
This setting indicates the high temperature threshold, if the cabinet temperature goes above this setting,
the alarm will go off.
Use UP or DOWN buttons to set the desired value and press ENTER to conrm.

Low Air Alarm Setting
The display will alternate between and the value
This setting indicates the low temperature threshold, if the cabinet temperature goes below this setting,
the alarm will go off.
Use UP or DOWN buttons to set the desired value and press ENTER to conrm.
Alarm Delay
The display will alternate between and the value
This setting indicates the amount of time in minutes the controller will delay the temperature alarm.
Use UP or DOWN buttons to set the desired value and press ENTER to conrm.

Door Frame Heater and Window Heater Settings
The display will alternate between and the value
This setting will enable or disable the door frame and window heaters.
1– heaters enabled
0– heaters disabled
Note: If you set the ashing value to “0”, the heaters will be disabled and the controller will skip the
heater settings. If the ashing value is set to “1”, the heaters will be enabled and the controller will
guide you through the heater settings.
Use UP or DOWN buttons to set the desired value and press ENTER to conrm.
The display will alternate between and the value
This setting indicates the walk-in temperature at which the controller will engage the door and window heaters.
Use UP or DOWN buttons to set the desired value and press ENTER to conrm.
The display will alternate between and the value
This value indicates the percentage the heater will stay on out of a 6-minute cycle.
Note: If condensation occurs on the door frame or on the window increase the percentage
the heater is on.
IMPORTANT!
ON COOLERS THIS SETTING MUST NOT EXCEED 80%.
Use UP or DOWN buttons to set the desired value and press ENTER to conrm.

Automatic Light Off Setting
The display will alternate between and the value
This value indicates the amount of time in minutes that the light will stay on before it will automatically turn off.
Note: “no” setting indicates that the light will stay on until it is turned off manually.
Use UP or DOWN buttons to set the desired value and press ENTER to conrm, the controller will return to normal
operation mode.
4 Air Temperature Probe Offset
As standard, the air temperature probe is located on the door frame, inside the walk-in. The IC will display the air
temperature at that location ONLY. However, IC can be adjusted to estimate the temperature of a remote location
inside the walk-in.
4.1 Calculating the Probe Temperature Offset
• Establish the location inside the walk-in where you want to monitor the air temperature.
Ex: Return Air Temperature (measured behind the evaporator)
• Using a calibrated thermometer, measure the air temperature at that location.
• Read the air temperature on the display of IC.
• The temperature difference between the two temperatures is the temperature offset. (TOFFSET)
Ex: Return Air Temperature (37˚F) - IC Displayed Temperature (40˚F) = Temperature offset (-3˚F)
(37˚F) - (40˚F) = - 3˚F

4.2 Adjust the Probe Temperature Offset
Press and hold ALARM MUTE button for ten seconds.
The display will alternate between and the value
Use UP or DOWN buttons to set this value to the temperature offset calculated in the previous step (TOFFSET) then
press ENTER to conrm, the controller will return to normal operation mode.
The display will reect the air temperature at the desired location.
Note: The air probe temperature offset is not to be used to make up for undersized or defective
refrigeration systems. If a different temperature is desired inside the walk-in, contact a refrigeration
technician to adjust your refrigeration system. Special care should be taken when adjusting the air
probe temperature offset. You should never adjust the air probe temperature offset for more than
5˚F. American Panel Corporation is not responsible for any losses such as food spoilage resulted
from misusing the air probe temperature offset.
5 Load Standard Settings
Press and hold UP and DOWN buttons, simultaneously, for ten seconds.
The display will alternate between and the value
Use UP button to set this value to “1” then press ENTER to conrm.
The display will show:
Enter the access code 055, use UP or DOWN button to change the blinking character then press ENTER to conrm.
