S204 Temp/Hum Events
—Enables or disables all temperature and humidity events. When
disabled, the setpoints to the right of S205-S211 will be hidden.
S205 Initial Time Delay
—Sets the delay after the fans have engaged before the S206-S211 can
become active. This delay is intended to prevent nuisance alarm trips when the unit starts. After the
unit fan has started and the delay has elapsed, the delays set on line S262-S267 take priority.
S206 High Supply Temperature
—Sets the high temperature threshold that will triggeran alarm
on the Liebert iCOM
®
and any monitoring system that may be connected. This threshold triggers an
alarm based on supply air temperature. It is ignored if the compressor (DX models) is not in
operation, the chilled water valve opening is less than 20% (chilled water models), within the first
5 minutes of a cooling call or if the electric heaters are energized.
S207 Low Supply Temperature
—Sets the low temperature threshold that will trigger an alarm on
the Liebert iCOM and any monitoring system that may be connected. This threshold triggers an
alarm based on supply air temperature. The temperature must stay two degrees above the threshold
for one minute and the event must be acknowledged before it will reset.
S208 High Return Temperature
—Sets the threshold temperature for a return high temperature
alarm to occur. The temperature must stay one degree below the threshold for one minute and the
event must be acknowledged before it will reset.
S209 High Return Humidity
—Sets the threshold humidity for a return high humidity alarm to
occur. The humidity level must be 2% below the threshold for one minute (nonadjustable) and the
event must be acknowledged before it will reset.
