GENERATION NITROGEN GENERATOR SYSTEM MANUAL
CLIMATE CONTROL (continued)
The temperature alarm settings have been preset to protect the generator system before known failure
values. Changing these values is generally not recommended; however, if the above factory values have
been inadvertently changed, the following programming information is provided for reference.
To change the factory default settings, enter the programming code sequence:
"1 Adjust-up" arrow
"2 Adjust-down" arrow
"3 Select"
"4 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 "4 Exit" button at any time while in the programming mode returns the
controller to the normal operating mode.
Press the "3 Select" button to continue programming. The set temperature "HI" LED illuminates with the
display indicating the 'cooling on' set point. The coolant 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 "1 Adjust-up" or "2 Adjust-down" arrow until the desired set
point is displayed. The range for this adjustment is 70°F to 126°F, (21°C to 52°C). When the adjustment is
complete, press the "3 Select" button to continue.
The set temperature "LO" LED is on with the display indicating the '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 "1 Adjust-up" or "2
Adjust-down" arrow 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 "3 Select" button to continue. The set alarm "HI" LED is on with the display indicating the high
temperature alarm set point. The alarm will activate at this temperature and will automatically reset at two
degrees Fahrenheit (one degree Celsius) below this temperature. Press the "1 Adjust-up" or "2 Adjust-
down" arrow to change the alarm set point to a point greater than 8ºF (or 4ºC) above the set temperature
"HI" set point, to 135°F (or 57°C).
Press the "3 Select" button to continue. The set alarm "LO" LED is on with the display indicating the low
temperature alarm set point. The alarm will activate at this temperature and will automatically reset at two
degrees Fahrenheit (or one degree Celsius) above this temperature. Press the "1 Adjust-up" or "2 Adjust-
down" arrow to change the alarm set point to a point no less than 8º F (4ºC) below the set temperature
"LO" set point to –20°F (or –29°C).
