previously. Key in the value and press ENTER key. The
new value will be entered into memory and the display will
advance to the next programmable value.
"DEFAULT" VALUE PROGRAMMING IN THE
PROGRAM MODE
Programmable values may be individually programmed
at start-up or anytime thereafter. For ease of
programming, once the type of refrigerant is programmed
in under the PROGRAM key, a password may be
programmed in to automatically program default values
into the micro. This will preset all programmable values
under the PROGRAM key to values that will allow
operation of the chiller under most operating conditions.
This allows quick start-up programming for typical chilled
water applications.
To program the default values into the micro after the
refrigerant type has been programmed, press the
PROGRAM key, key in the numbers "6140", and press
ENTER. As the numbers are keyed in, Qs will appear:
When the ENTER key is pressed, the following message
will appear:

Key in a "1" for YES, if default setpoints in Table 4 are
desired. Key in a "0" for NO, if individually programmed
values are desired. After the desired option is
programmed, press ENTER to store the selection into
memory.
NOTE: Keep in mind that it is often easier to select
Default Setpoints and then reprogram a few that
require changing, versus programming each
individual program option.
If a "0" is selected, the display will return to the STATUS
display. If a "1" is selected, the display will momentarily
display the message shown below before returning to the
STATUS display.
