Koolance EX2-755-R - Manual (Page 6)

4 5 User Manual System Features
To change this setting for an individual sensor, choose the desired channel with
SET, and press and hold
▼ + ▲ together for 3 seconds. The alarm temperature
will begin flashing. You may change this value from 0ºC (32ºF) up to 99ºC (210ºF).
The normal temperature reading will resume if you do not press any buttons for
4 seconds.
To reset all temperature alarms to their default (55ºC / 131ºF) setting, press and
hold the ºC/F button until “dEF” flashes in the display. NOTE: This will also reset
the fan speed mode to “auto”, and pump power to 100%.
If any sensor reaches 3ºC (5ºF) above the alarm temperature, the system will
activate the “ATX pass-through” wire relay. For a computer, this is equivalent to
holding in the power button for several seconds to force it to shut down. With default
alarm settings, this means the shutdown signal is sent if any sensor reaches 58ºC
(136ºF). See “Relay Jumper” for configuring the shutdown signal.
CAUTION: Generally, sensors report liquid temperature at the water
block, which is typically 5-10°C (9-18°F) lower than the actual heat
source. This difference must be considered if adjusting alarm/shut-
down temperatures. Activating alarm/shutdown modes at too high of
temperature may be unsafe. Please see a Koolance CPU water block
user manual for an example of attaching this sensor.

Alarm & Shutdown Settings
By default, the Koolance audio alarm will sound if any sensor reaches 55ºC (131ºF).
When the system alarm sounds, the appropriate LED temperature will flash in the
display and the radiator fans and pump will increase to 100% power.
