Modes
The CTR-CD10 offers seven display options. All are reached by continually
pressing the SET button:
1. Temperature sensor #1 is displayed
2. Temperature sensor #2 is displayed
3. Temperature sensor #3 is displayed
4. All temperature sensors are cycled automatically
5. Fan setting is displayed (“F” is shown as the mode)
6. Pump setting is displayed (“P” is shown as the mode)
7. All temperatures, fan, and pump settings are cycled automatically
Temperature Sensors
The CTR-CD10 can monitor up to 3 temperature sensors (included). The
fi rst LED digit indicates which sensor channel is currently displayed in the
temperature reading. To cycle through sensors, press SET.
Fan Speed
This option adjusts connected fan speeds. Higher speeds can improve
performance, but will produce more noise. There is 1 automatic and 10
2
manual fan settings (1-10). From the fan (“F”) or any cycle mode, press the
▼
or ▲ buttons to adjust fan settings, or hold down an arrow to skip to the lowest
or highest mode directly.
Automatic mode will adjust the fans for you based on temperature values from
sensor #1. This mode is reached by lowering the fan setting to “0” (Aut / A will
be displayed).
Pump Speed
There are 10 manual pump settings (1-10). From the pump (“P”) mode, press
the ▼ or ▲ buttons to adjust the pump settings, or hold down an arrow to skip
to the lowest or highest mode directly. There is no automatic mode available
for the pump setting.

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 fl ash in the
display and the fans and pump will increase to 100% power.

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 fl ashing. 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” fl ashes in the display. NOTE: This will also reset
the fan speed mode to “auto”, and pump power to 100%.
If any temperature sensor reaches 3ºC (5ºF) above the alarm temperature, the
system will shutdown power to the computer via the Koolance “ATX pass-through”
wire. With default alarm settings, this means the system will shutdown if any sensor reaches 58ºC (136ºF).
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/shutdown
temperatures. Activating alarm/shutdown modes at too high of temperature can cause hardware damage. Please see a Koolance CPU water
block user manual for information on attaching this sensor.

Connect a 12 Volt 4-pin Molex plug from the power supply to the power connection on the rear of the CTR-CD10. Without this important connection, the unit will
NOT operate.
ATX Power Switch
The ATX “pass through” lead is responsible for shutting off your computer if sensor channel #1 reaches
3ºC (5ºF) above the preset alarm temperature. Connect the male ATX power lead from the CTR-CD10
to the chassis main power switch.
Connect the female ATX power lead from the
CTR-CD10 to the motherboard’s power switch
connection (often marked “PWRSW”, “PWSW”,
or “PWBT”).
This is the connection that would normally receive
the chassis power switch lead directly.
CAUTION: The auto shutdown safety features of your PC4-1000
will not function properly without connecting the ATX power switch
!
lead.
NOTES: If the LED Display Panel shows 5 - 0 or 5 - 5...
5 - 0 (“S - O”): Sensor open. This indicates a temperature sensor can not be
detected for a given channel. If there is no sensor connected to a channel, this
is its normal status.
5 - 5 (“S - S”): Sensor short. This indicates that the sensor may be faulty or electrically bypassed. If the sensor is listed with an “S-S” status, the cooling system
alarm will sound. The sensor will need to be replaced.
