RCC Hardware and Setup

COMMUNICATIONS

Communications between the chiller and the remote
chiller will be limited to once every 16 seconds. This
results in a time lag in displays as well as time lags in
commands to the chiller from the Remote Control Cen-
ter. Keep this in mind when using the remote panel. In
addition, when power is first applied to the remote
panel, a time lag of 30 sec. to 2 min. may be required
before initial communications is established.

KEYPAD OPERATION

ARROW KEYS

During programming, these keys will increase or de-
crease the numerical value appearing on the display.

During normal viewing of data, the arrow keys are used
to scroll up or down through the data fields.

ENTER/

ADV

Enter key is used to store new values into memory.
Other keys on the unit are self explanatory.

PROGRAMMING SETUP AT THE CHILLER

Press the PROGRAM key and scroll by repeatedly
touching the ENTER key. At the display titled
“COMMUNICATIONS MODE” select LOCAL or
REMOTE using the arrow keys.

AT THE RCC

No programming setup is required.

EPROM VERSION DISPLAY

At the RCC, touch the HISTORY key followed by the
down arrow. Press arrow key 2x to see chiller eprom
version.

At the chiller, touch the OPER DATA and the * key to
display the eprom version.

The RCC should have the number 12 in the version
format CXXX. 12.XX A two compressor chiller should
have the number 09; and a chiller that has three or four
compressors should have the number 10 in the version
format.

Note that the last two digits will vary as changes are
made to the software.

POWER LOSS

In the event of a power loss to the Remote Control Cen-
ter, the microprocessor in the chiller control panel will
continue to adhere to the setpoints and commands dic-
tated from the Remote Control Center prior to the power
loss for five minutes. At the end of the five-minute pe-
riod, the chiller will revert to local control if communica-
tion is not re-established. When communications are
re-established after power is returned, the chiller will
honor all commands programmed into the Remote Con-
trol Center.

In the case of a remote shutdown before the power loss
occurred, the chiller may start on local control, if de-
