INSTALLATION INSTRUCTIONS
The Thermoelectric Temperature Controller can be mounted in any convenient dry location
near the Thermoelectric Cooler (TEC). The location should take into consideration the
desired position of the thermistor sensing bead and the length of the supplied thermistor
harness, roughly 28 inches (700 mm) long. It is recommended, but not required, that the
thermistor sensing bead be located at the inlet of the enclosure-side fan.
Mount the controller using the four supplied 10-24 self-tapping screws. Drill .172 inch
(4.4mm) diameter pilot holes in the mounting plate using the .25 inches (6.4 mm) diameter
holes near the corners in the back plate as a template. The cover must be removed to gain
access to the mounting holes.
Power Supply
Class 2 power supply is required.
Wiring
With the exception of the thermistor, all wiring between the TEC and the controller, and
between the controller and input power supply, is to be supplied by the user. Use copper
supply wires.
Recommended wire gauges for wiring:
Power and earth ground inputs .................................14 AWG
TEC Module and earth ground outputs ...................14 AWG
Fan outputs ........................................................................20 AWG
Alarm outputs ...................................................................20 AWG
Description Source Destination AWG
Input Power to Controller External Power Source TEC Controller 14
Input Earth Ground to Controller External Earth Ground TEC Controller 14
TEC Module Power TEC Controller TEC Terminal Block 14
TEC Module Earth Ground TEC Controller TEC Terminal Block 14
TEC Fan Power TEC Controller TEC Terminal Block 20
Alarm Outputs TEC Controller External Alarm Input 20
Connect the TEC as shown in the wiring diagrams, see Wiring Diagram on page 3. Ensure
that higher potential conductor is connected to the (+) terminal and lower potential is
connected to the (–) terminal. If heating is called for (as determined by the thermistor
reading relative to the cooling and heating setpoints), the controller will automatically
reverse the DC voltage to the TEC modules (peltier chips).

Setup
Cooling and heating temperature setpoints are factory set to 95 F/35 C for cooling and 59
F/15 C for heating.
These setpoints can be changed by adjusting the two dip switches on the printed circuit
board assembly labeled “Cool” and “Heat”.
Note: The heating function includes a disabled position.

Operation
The controller will command the TEC to cool if the temperature read by the thermistor is
above the cooling setpoint, and heat if the temperature is below the heating setpoint. If
the temperature read by the thermistor is between the cooling and heating setpoints, the
controller will be in a standby mode with no power applied to the TEC modules.
When going from cooling to heating or heating to cooling, the control logic provides
for a minimum ten minute delay when applying power to the peltier chips. The delay is
an added feature to minimize the stress on the TEC modules and controller by assuring
that the peltier chip internal temperatures are able to equalize before reversing the DC
current through the chips. The delay will only aect the controller response in the unlikely
circumstance that the system experiences a rapid temperature swing from above the
cooling setpoint to below the heating setpoint, or visa versa.
The normally open (NO) alarm output contact will close when an alarm occurs. The
normally closed (NC) contact will open when an alarm occurs.
