General Description
The MTTC-1410 Thermoelectric Temperature Controller is a precision
instrument that utilizes Pulse Width Modulation (PWM) control technology
to provide accurate temperature control of thermoelectric devices. The
MTTC-1410 is a bi-directional controller with selectable voltage output
and a full “H” bridge capable of load currents of up to ten amperes. The
unit’s LED front control panel can be used to adjust the setpoint
temperature, to view the current temperature, or to fine-tune the control
parameters for higher accuracy or faster response.
Specifications and Features
Input Power: 110(2A)/220VAC(1A), 50~60Hz
Range of selectable DC output voltages: 3, 7, 12, and 14 VDC
(PWM)
Maximum Output Current: 10A
Control temperature range: -100°C to 200°C
Control stability: 0.1°C/24h
Temperature sensor: 2-wire Pt1000 RTD (included)
Control output: Proportional control with automatic reset and
rate (PID), 500 Hz Pulse Width Modulation (PWM)
Dimensions: 15cm (5.9”) × 12.5cm (4.9”) × 26cm (10.2”)
3.5 digit LED display, 4-button user interface
Extra terminals for constant 12VDC fan operation (up to 1
Ampere)

Product Handling
Do not operate this unit before reading this manual.
The MTTC-1410 was designed, built, and packaged to withstand the shock
and vibration normally associated with shipment by common carriers.
Occasionally, improper handling during shipment, such as excessive
vibration, crushing, etc., will cause damage to the product. Therefore, a
thorough inspection should be provided upon receipt of all shipments.
Any packaging tears, dents, scratches, or loose objects are signs of
damage and should be noted on the Freight Bill. Packages should be
opened promptly and units inspected for concealed damage. If damage is
found, an immediate claim must be filed with the freight carrier and an
inspection requested. Retain all packing materials. Melcor cannot be
responsible for the Consignee’s failure to file a timely freight claim.
WARNING
Electrical Shock Hazard
A. ENSURE THAT THERE IS A CIRCUIT BREAKER ON THE LINE AND THAT IT
COMPLIES WITH UNIT’S ELECTRICAL REQUIREMENTS.
B. PLUG UNIT INTO GROUNDED ELECTRICAL OUTLET ONLY.
C. IF THE ELECTRICAL SUPPLY CORD IS DAMAGED, IT MUST BE REPLACED
BY A CORD WITH AN EQUAL OR HIGHER RATING.
D. UNPLUG THE POWER CORD BEFORE TURNING THE REAR PANEL VOLTAGE
ADJUSTMENT KNOB OR CHANGING THE FUSE.
Failure to follow the above precautions could result in electrical shock, fire, personal
injury, or damage to the unit, and will void the warranty.

Getting Started
Figure 1 - Rear Panel
1. Connect a Pt1000 RTD temperature sensor (provided) to the screw
terminals in upper right corner of rear panel (see Fig.1).
2. Plug the AC power cord into the input receptacle at the left of the
rear panel.
3. Turn power switch to “ON”.

Figure 2 - Front Panel
4. At the user interface in the front (Figures 2 & 3), adjust the setpoint
and, if desired, the tuning parameters or calibration offset (see the
Controller Adjustment section on the next pages for specific
instructions).
5. Back at the rear panel, turn the AC power switch to “OFF”, and
disconnect the power cord plug from the receptacle
6. Connect your Thermoelectric Cooler (TEC) to the screw terminals
located in the lower left corner. Polarity is critical here; if you are
not certain of the TEC’s polarity, please contact Melcor.
7. If you have a 12VDC fan, connect it to the screw terminals for the
fan.
8. Using the voltage adjustment knob, select the peak pulse voltage.
In almost all cases, this voltage should be less than or equal to the
“Vmax” rating of the TEC. There are other technical considerations
based on heat-sinking and temperature that may affect your choice
of voltage. If you are not certain of what voltage to choose, please
contact Melcor.
9. Re-connect the power cord, and turn the AC switch to “ON”.

In Figure 4, red represents solidly lit digits, while blue represents a
blinking digit. The value of a blinking digit can be changed by pressing
the “Up” or “Down” keys. Pressing the cycle key (“ ”) changes the
position of the blinking digit one step to the left.

Selecting the setpoint temperature.
Press and hold the “Set” button for 3 seconds. The setpoint
temperature will be displayed. Use the “ ” key to select a
digit, and then push either the “Up” or the “Down” key to
change the value of the blinking digit. After choosing the set
point, press “Set” once more to enter the setpoint
temperature. (The “Set” button must be pressed to store the
new setpoint; otherwise, the controller will revert to the
previous setpoint.)
Changing PID terms and the calibration offset value.
Press and hold both the “Up” and “Down” buttons for 3
seconds. The Proportional band adjustment will be displayed.
Use the “Up” or “Down” keys to scroll through the selection
list to select which item is to be adjusted (Proportional band,
Integral Time, Derivative Action, Calibration Offset). Press
“ ” to select the digit to be changed, and then push “Up” or
“Down” key to change the value of blinking digit. Press “Set”
once more to enter the new values. (The “Set” button must
be pressed to store the new values; otherwise, the controller
will revert to the previous values.)
Serviceability
No special maintenance is required when using the MTTC-1410. Do not
attempt to open the unit. There are no user-serviceable internal parts.
Opening the unit will void the warranty and could result in injury.
All returns must be assigned a Return Materials Authorization number
(RMA#) in advance. Returns received without an RMA# may be refused.
In the event that a return is required, the Customer should call Melcor’s
Customer Service Department at (609) 393-4178. The Customer will be
asked to fill out an RMA form so that an RMA# can be issued. All returns
must be securely packed to prevent shipping damage and must be clearly
marked with the RMA# on the box. Consignor shall pay freight charges
on all returns.
