CTR-CD1224 User Manual v 1.0

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:

Pump Voltage Jumper: Configure the pump
output for a maximum of 12-Volts or 24-Volts.
Misconfiguration could damage the pump!

Shutdown Relay: Configure the safety
shutdown relay (labeled “ATX”) as Normally­Open (NO) or Normally-Closed (NC).

ATX Shutdown Relay

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).

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.

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.

!

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.

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.

The pump voltage jumper
should be set for the maximum
voltage capability of the pump,
either 12V or 24V.

CAUTION: Do not power 12V pumps at the 24V setting! This

can permanently damage the pump.

!

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”.)

NOTE: The shutdown temperature must be at least 1ºC (1-2ºF) higher than the alarm

temperature first. The minimum and maximum temperature range allowable is 0-99ºC (32­210ºF).

FAN SET

This unit has three fan channels which can be independently adjusted. Alternatively, use the
master fan channel (“ALL FANS”) to adjust all fan channels simultaneously.

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. Setting
alarm/shutdown modes at too high of temperature can eliminate this feature’s
effectiveness. The default Koolance settings are designed to help compensate
for temperature differences of a typical computer CPU/GPU water block.
