FIELD PROGRAMMING GUIDE -MINI MAX
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
