General Safety Warnings
This manual must be read and followed carefully before installation and operation. All warnings in this
Instruction Manual apply to both the TC-720 and TC-720 OEM versions of the controller. Where “TC-720” is
referenced, it is used generically and interchangeably for both the TC-720 and the TC-720 OEM versions of the
controller, except where otherwise specifically noted.
THE LATEST REVISION OF THIS MANUAL IS AVAILABLE AT www.tetech.com. Verify that you are using the
latest revision available.
Do not use in an explosive or potentially explosive environment.
The TC-720 is designed specifically for its intended purpose of providing temperature control of TE
Technology’s thermoelectric devices only. The temperature controller is intended for light industrial,
laboratory, or similar use; it is not intended for household or medical use.
Do not use the TC-720 to control capacitive or inductive loads as this could damage and/or overheat the
controller. Examples of capacitive or inductive loads include but are not limited to motors and solenoids.
Do not use if the controller has been damaged.
Only qualified technicians should install this controller.
Do not allow the electrical connections or components on the printed circuit board, including those on the
reverse side of the JP3, JP5, JP6 and JP7 connectors, to touch any electrically conductive surfaces.
Do not operate in an environment where the controller could come in contact with condensation, water,
metal shavings, dirt or other contaminants, or electrically conductive materials.
Use ESD (Electro Static Discharge) protection when installing or handling the controller.
Do not touch any of the electrical connections or components of the TC-720 while the controller is
energized. Doing so can disrupt the function of the controller.
The printed circuit board underneath JP7 and exposed components on the printed circuit board could
exceed 70 °C under normal operation. Use caution! Protect against accidental contact with hot surfaces.
Improper tuning of this temperature controller can lead to overheating of the load (e.g. cooling assembly,
heater, etc.) and other related equipment.
Use protection devices to prevent hazardous conditions and/or damage to equipment.
Each power input that is used must be fused separately. Alternately, a power supply with integral over
current protection can be used if it is appropriately sized for protecting the controller/TE device.
Thermoelectric devices are capable of developing potentially hazardous temperatures and/or other
potentially hazardous conditions. Read and follow the instructions in TE Technology’s Thermoelectric
Cooling Assembly (TCA) Instruction manual before using this controller. If using a thermoelectric device
from another manufacturer, read and follow all instructions pertaining to that manufacturer’s device
before operating the controller. The (TCA) Instruction manual is available for download from TE
Technology's website a
