The chilled liquid is glycol. The Cooling Setpoint can be
programmed from 10°F to 70°F (-12.2°C to 21.1°C).

When programmed for LOCAL, an ISN or RCC control
can be used to monitor only. The micropanel will oper-
ate on locally programmed values and ignore all com-
mands from the remote devices. The chiller will com-
municate and send data to the remote monitoring de-
vices.

This mode should be selected when an ISN or RCC con-
trol is to be used to control the chiller. This mode will
allow the ISN to control the following items: Remote Start/
Stop, Cooling Setpoint, Load Limit, and History Buffer
Request. If the unit receives no valid ISN transmission
for 5 minutes, it will revert back to the locally programmed
values.
Option 7 – Unit Control Mode

Unit control is based on return chilled liquid temp. It can
only be selected on units that have 4 or 6 compressors
(dual system units).
