Koolance CTR-CD1224-R - Manual

ATX Shutdown Relay
Connect the female ATX lead to the motherboard’s
power switch connection (usually marked “PWR”,
“PWRSW”, “PWSW”, or “PWBT”). This is the
connection that would normally receive the chassis
power button directly.

Unit
There is no polarity orientation with the ATX
lead. For computer use, connect the male
shutdown lead from the Koolance unit to your
computer’s front chassis power button.
The ATX lead is responsible for sending the shutdown signal if any sensor
reaches the preset temperature (detailed later). This can be configured as
NC (normally closed) or NO (normally open) by attaching the two-pin wire
to the corresponding pins. For computers, use “NO” (normally open).
To Motherboard
The rear of the unit accepts various connections to integrate with your cooling system. The
temperature sensors may come pre-connected. If not, connect them per the diagram below:
Power Connection
Plug the included power harness into
the location on the rear of the unit
marked “Power”. To this, connect a 12
Volt 4-pin Molex plug from your power
supply.
Fan Connection
This unit has three connections to power radiator fans. Multiple fans can be combined into
a single plug. (A fan wiring harness is optionally available from Koolance).
CAUTION: The total combined amperage of all fans connected to the unit can
not exceed 4.5A. The maximum load on a single fan header is 2.0A.
!
Flow Meter Connection
The cooling system can show values for one Koolance flow meter (sold separately). Connect
a flow meter to the appropriately labeled plug. (Note: INS-FM18 and INS-FM19 should
connect to the plug labeled “INS-FM17”.)

Pump Connection and Voltage Jumper
Plug the included pump wiring harness into the rear
“Pump” connector. Different plugs are provided to
connect a single 12 Volt or 24 Volt DC pump. (Max.
output power = 36W @12V, 50W @24V.) Do not
connect more than one pump.
CAUTION: Do not power 12V pumps at the 24V setting! This
can permanently damage the pump.
