5.2 Wiring Diagram
Refer to the wiring diagram below for correct electrical connections. Ensure all connections are secure and comply with local electrical codes. The controller operates on 110VAC.
Figure 5.3: Wiring diagram for the MTC-5060 controller. Terminals 1-2 for power, 3-5 for sensors, 6-9 for output loads (cooling and defrosting).
- Power Supply: Connect 110VAC to terminals 1 and 2.
- Sensor Connections: Connect the NTC sensor(s) to the designated terminals (e.g., 3, 4, 5). The MTC-5060 supports two sensors for storage temperature and defrosting temperature.
- Output Loads: Connect cooling and defrosting loads to the respective relay output terminals (e.g., 7-8 for cooling, 8-9 for defrosting). The relay output contact capacity is 3A/110VAC.
6. Operating Instructions
The MTC-5060 features a user-friendly interface with dedicated buttons for common functions and parameter settings.
6.1 Display and Indicators
The controller has two digital displays:
- Upper Display: Shows the current room temperature.
- Lower Display: Shows the set temperature.
Indicator lights provide visual feedback on the operating mode (e.g., cooling, defrosting).
6.2 Setting Temperature
- Press the Set button to view the current set temperature.
- While the set temperature is displayed, use the Up and Down arrow buttons to adjust the desired temperature value.
- Press the Set button again to confirm and save the new setting.
6.3 Defrosting Control
The MTC-5060 supports automatic and manual defrosting.
- Automatic Defrost: Configured through parameters (defrost cycle, defrost time). Refer to the detailed parameter settings section (if available in full manual) for adjustment.
- Manual Defrost: Press the Forced Def. button to initiate a manual defrost cycle.

9. Troubleshooting
This section provides solutions to common issues you might encounter with your MTC-5060 controller.
| Problem | Possible Cause | Solution |
|---|---|---|
| Controller does not power on. | No power supply or incorrect wiring. | Check power connections (terminals 1 & 2) and ensure 110VAC supply. Verify wiring against diagram. |
| Temperature display is inaccurate or shows "EE". | Sensor error or faulty sensor. | Check sensor connections. Ensure the sensor is not damaged. Replace sensor if necessary. Perform temperature calibration if readings are consistently off. |
| Cooling/Defrosting not activating. | Incorrect set temperature, parameter settings, or faulty output relay. | Verify set temperature and differential. Check relevant parameters (e.g., compressor delay, defrost cycle). Inspect wiring to the cooling/defrosting load. |
| High/Low temperature alarm triggers frequently. | Alarm limits set too close to operating temperature or actual temperature fluctuation. | Adjust high/low temperature alarm limits. Investigate the cause of temperature fluctuations in the controlled environment. |
If the problem persists after attempting these solutions, please contact Elitech customer support for further assistance.
