VERVIEW
This is an extremely advanced
controller featuring 2 controllers
which individually feature: Temperature Display with On-Screen Programming, Fahrenheit or Celsius Display,
Auto & Manual Modes, Low Voltage Trigger, Automated On & Off and Variable Speed based on Temperature,
Auto or Manually Set Fan Speeds, Alarm with Contact Closures, both NC and NO, and an audible alarm that can
also be disabled. It is fully programmable, easy to install and configure, and is extremely reliable. The unit also
features an additional four 12V DC plugs for powering other low voltage devices such as IR systems. The unit
can be installed by placing it on top of other components or in a rack requiring only 1U of free space.

: This is exclusively a low voltage
(12 V DC),
controller so for high voltage or ventilation systems, use the Advanced
Ventilation Controller. Even for low voltage ventilation applications, the TC-AVC would be more appropriate.
Standard Application:
For the most common applications, two or more low voltage fan units would be
connected to the controller. Both controllers would be set to auto and use default settings for on, high speed,
and alarm set points (On - 85°F, High - 105°, Alarm - 115°). With this in mind, the unit takes just a few minutes
to install and configure. Appropriate uses would be to control fan units that directly cool equipment and/or for
venting racks or cabinetry. For example, one controller could be used for the ventilation fans while the second
controller is used for spot coolers (fans directly cooling components).
Advanced Features:
The trigger and alarm features are the most advanced features with this unit. Rarely
would we recommend using the trigger feature to turn the fans on as temperature, thus Auto mode, is the most
effective and efficient way to turn fans on and off. The alarm contact closures provide the ability to connect the
controller to a whole house controller and provide notification of a potential problem. Depending on the control
system, commands could then be sent to volume down or power off the system and by having both NC and NO
options; it is compatible with most automation systems utilizing contact closures.

OCATING THE

NIT
The unit can be located most anywhere within a system. The sensors for reading the temperatures are
approximately 3’ and 6’ long which should reach most areas within even the largest of systems. Easy access to
the unit to read the display and adjust the programming are also considerations. Since the unit is very compact,
it can be placed on top of a receiver or amplifier, just do not block ventilation. If using on top of a receiver or
amplifier, consider using a cooling product such as the Dual Fan (CP-DF) unit to assist in keeping the component
cool.
Mounting Notes:
To install in a rack, attach the rack mount ears using the supplied screws and remove the
‘feet’ by removing the screw, removing the foot and re-inserting the screw. It’s best to work one foot at a time.
For non-rack applications, install the hole plugs in the rack ear mounting holes for a finished looked.

ONNECTING THE
U
NIT
Note: Connecting the unit is very easy and straightforward but note that some features will not be used,
thus some terminals will not be utilized and nothing further needs to be done with them.
Sensors for both units MUST be connected before powering the unit on or the alarm will sound and the
unit will not function.
Power In:
The power in jack is a 2.5mm coax jack and the unit requires 12V DC, up to 5A. Center pin positive.
Additional Power Jacks:
These are 2.1mm coax jack and outputs 12V DC. These jacks are intended for
relatively low amperage items, perhaps 100-200mA each.
