OPERATING THE SYSTEM

 

Once the Ice Qube system has been installed onto the 
enclosure and the power cord has been attached to a 
properly grounded electrical outlet with adequate voltage 
and current supply, the unit is ready for operation.  As 
soon as electrical power is supplied to the Ice Qube 
system, the cool air stream blower will start to operate.  
The blower will run continuously so that the controller 
can monitor the enclosure’s internal temperature.  The 
enclosure temperature will be displayed on the face of 
the controller. 
 
If the enclosure temperature is greater than the factory 
cooling setpoint of 80°F, the “Cool” status LED will flash.  
This indicates that the compressor’s automatic off cycle 
timer is working.  (The off cycle timer is factory set at 3½ 
minutes).  At the end of 3½ minutes, the compressor and 
the condenser air blower will begin to operate.  This 
signifies that the cooling system has begun operation to 
remove heat and humidity from the enclosure.  This 
procedure may take 20 to 30 minutes before it reaches 
full capacity. 
 
If the heat load within the enclosure is less than the 
cooling

 

capacity of the Ice Qube system, the 

temperature on the digital display will begin to decrease.  
When the temperature inside the enclosure decreases 7 
degrees Fahrenheit below the ‘cooling on’ setpoint, the 
compressor and the condenser blower will cycle off.  The 
cool air blower will continue to operate, circulating air 
within the enclosure.  The controller has a factory 
programmed temperature differential of 7 degrees 
Fahrenheit.    Example:  “Cooling on” @ 80°F; “Cooling 
off” @ 73°F. 
 

NOTE:  There is a dead band programmed 

into the controller that prevents 
heating and cooling from operating 
simultaneously.  

 
 
 
 

PROGRAMMING THE CONTROLLER

 

The digital controller has many features that may or may not 
be required for your application.  However, the controller has 
been programmed at the factory with typical default settings for 
immediate system operation.  Please review the following 
default settings: 
 
1.  Cooling system on temperature      

     80° F 

2.  Heating system on temperature     

     50° F 

(optional)

 

3.  High enclosure temperature alarm                100°F 

  

4.  Low enclosure temperature alarm 

     40° F 

5.  Audible and Visual alarm  

 

     “ON” 

6.  Digital display in degrees                           Fahrenheit 

 

7.  Filter maintenance alarm 

       0 days – Disabled 

8.  High condenser temperature alarm 

      170° F 

To change the factory default settings, enter the programming 
code sequence: 

 

“+” (plus sign) 

“-”  (minus sign) 

“Select” 

“Exit” 

 

After pressing the above sequence the program LED should 
illuminate along with three alternating flashing boxes on the 
display face, indicating the code was accepted.  If no selection 
is made within one minute, the system returns to the normal 
operating mode. 

 

Note: 

Pressing the “Exit” button at any time 
while in the programming mode returns 
the controller to the normal operating 
mode.

 

 

Press the “

Select” 

button to continue programming.  The set 

temperature “HI” LED illuminates with the display indicating the 
‘cooling on’ setpoint.  The compressor will begin operation at 
this temperature and will remain operating until the enclosure 
temperature decreases approximately seven degrees 
Fahrenheit (four degrees Celsius). 
 
Press the 

“+”

or 

“-“

 buttons until the desired set point is 

displayed.  The range for this adjustment is 70° to 126°F, (21° 
to 52°C).   When the adjustment is complete, press the 

Select”

 button to continue. 

 
The set temperature “LO” LED is 

on

 with the display indicating 

the (optional) ‘heating on’ set point.  The heating system will 
begin operation at this temperature and remain operating until 
the enclosure temperature increases approximately seven 
degrees Fahrenheit (four degrees Celsius).  Press the 

“+”

or 

“-

 buttons until the desired set point is displayed within a range 

of 0°F to 63°F (-17.8°C to +17°C). 

 

NOTE:  Review alarm settings if the ‘cool on’ or 

‘heat on’ set points have been changed, 

 
Press the 

“Select

” button to continue.  The set alarm “HI” LED 

is 

on

 with the display indicating the high temperature alarm 

setpoint.  The alarm will activate at this temperature and will 
automatically reset at two degrees Fahrenheit (one degree
