8.3 PROGRAMMING “DEFAULT” VALUES
Programmable values may be individually programmed
at start-up or any time thereafter. For ease of program-
ming, once the type of refrigerant is programmed in
under the Program key, a “defaults password” may be
programmed to automatically program default values
into memory. This will preset all programmable values
under the Program key to values that will allow opera-
tion of the chiller under most operating conditions. This
allows quick start-up programming for typical chilled
water applications.
To program the default values into memory, first press
the PROGRAM key followed by the ENTER key, to
program the “refrigerant type”. Press the Program key
again, key in the numbers “6140”, then press Enter. As
the code is being keyed in, the digits are not displayed
but are shown as “ * ” as shown:
When the Enter key is pressed, the following message
will appear:
P R O G R A M M O D E
* * * *
D E F A U L T S E T P O I N T S ?
1 = Y E S , 0 = N O, 1
P R O G R A M O P T I O N S S E T
T O D E F A U L T V A L U E S
Key in a “1” for if default setpoints are required, or a
“0” for individually programmed values, then press En-
ter to store the selection into memory.
If individual programming is selected, the display will
now return to the Status display. If a default setpoints
have been selected, the display will momentarily display
the message shown below before returning to the Sta-
tus display:
It is often easier to select Default
Setpoints and then reprogram a few
that require changing rather than pro-
gramming each individual value from
scratch.
A list of the default values entered into memory, if this
program option is selected, is shown below. Also in-
cluded are minimum and maximum allowable pro-
grammed values.
