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 onboard 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 airflow 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:

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 45oF. The
alarm’s set points and delay times are fully programmable to user’s needs.

1.3 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.

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:
The access code is 055, use UP or DOWN button to change the blinking character and press ENTER to confirm.
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 confirm.
Low Air Alarm Setting
The display will alternate between and the value
This setting indicates the low temperature threshold, if the cabinet temperature goes this this setting, the alarm
will go off.
Use UP or DOWN buttons to set the desired value and press ENTER to confirm.
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 confirm.

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 flashing value to “0”, the heaters will be disabled and the controller will skip the heater
settings. If the flashing 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 confirm.
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 confirm.
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 confirm.
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.

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 (behind the evaporator)
Using a calibrated thermometer, measure the air temperature at that location. TMEASURED
Read the air temperature on the display of IC. TIC
The temperature difference between the two temperatures is the temperature offset. TOFFSET
Ex: Return Air Temperature (measured behind the evaporator) 370F
IC Displayed Temperature 400F
The Temperature Offset will be: (370F) - (400F) = -30F
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 confirm, the controller will return to normal operation mode.
The display will reflect 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 50F.
American Panel Corporation is not responsible for any losses such as food spoilage resulted from
misusing the air probe temperature offset.

This value sets the cabinet type, use UP or DOWN buttons to choose “co” – cooler, “Fr” – freezer, “br” – beer
cooler, or “Aut” – automatic selection.
If the cabinet type is set to cooler, freezer, or beer cooler the unit will return to normal operation mode and all
the alarm and door heater parameters will be set to default, see chapter 1.
If the room type is set to automatic selection, user will have to set the detection time in hours.
The display will alternate between and the value
Set a low value (1hr) if the cabinet is already at the desired temperature, set a higher value (12hrs) if the cabinet
is pulling down such as during the initial start-up.
