5.3 Sensor Connection
Connect the two temperature sensors to the designated terminals as shown in the wiring diagram. One sensor is typically for room temperature (storage), and the other for defrosting temperature (evaporator). Ensure sensors are placed correctly for accurate readings.
5.4 Power Connection
Connect the 110VAC power supply to terminals 1 and 2. Ensure the power source is stable and matches the specified voltage. Connect the cooling and defrosting loads to their respective output terminals as indicated in the wiring diagram.
6. Operating Instructions
6.1 Power On/Off
Once wired correctly, apply power to the unit. The display will illuminate, showing the current room temperature and the set temperature. To power off, disconnect the main power supply.
6.2 Setting Temperature
To adjust the set temperature, press the 'Set' button. The set temperature will flash. Use the 'Up' and 'Down' arrow buttons to change the value. Press 'Set' again to confirm and exit.
6.3 Parameter Settings
The MTC-5060 features a multifunctional button panel for easy access to common settings without navigating complex menus. For advanced parameters such as compressor delay, defrost cycle, or temperature calibration, refer to the detailed parameter list in the full user manual (not included here). Typically, these settings are accessed by holding down specific buttons for a few seconds.

6.4 Manual Defrost
To initiate a forced defrost cycle, locate the 'Forced Def.' button on the panel and press it. The defrost indicator will illuminate, and the unit will enter a defrost cycle. The duration of the defrost cycle is determined by the configured parameters.
Note: This unit displays temperature in Celsius. Ensure your application is compatible or convert readings as needed.
7. Maintenance
- Cleaning: Regularly wipe the display panel and casing with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Connection Checks: Periodically inspect all electrical connections to ensure they are tight and free from corrosion.
- Sensor Integrity: Ensure the temperature sensors are clean and properly positioned. Avoid bending or damaging the sensor cables.
- Ventilation: Ensure the area around the thermostat is well-ventilated to prevent overheating.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display shows 'HH' or 'LL' | Sensor error (open circuit or short circuit) | Check sensor connections. Replace faulty sensor if necessary. |
| Temperature not stable or inaccurate | Improper sensor placement; incorrect parameter settings | Reposition sensor away from heat sources or drafts. Verify parameter settings (e.g., hysteresis). |
| Unit not cooling/defrosting | No power to loads; incorrect set point; faulty wiring | Check power supply to the unit and loads. Verify set temperature and other parameters. Inspect wiring for loose connections. |
| Display is blank | No power supply | Check power connections and ensure 110V supply. |
