- Cut a rectangular opening in the panel according to the controller's dimensions (refer to specifications for exact cutout size).
- Insert the controller into the opening from the front.
- Secure the controller using the integrated mounting clips on the sides.
4.2. Wiring
All wiring must comply with local and national electrical codes. Refer to the wiring diagram provided with the product for specific connection points. Ensure proper grounding.
- Connect the main power supply (230V AC) to the designated terminals.
- Connect temperature sensors (NTC 5K and 10K, Pt1000, PTC) to the sensor inputs.
- Connect the compressor, fan, and defrost heater loads to the respective relay outputs. The controller features 16A relays for robust connections.
- Utilize the multi-purpose digital inputs for functions such as defrost start, day/night control, or door open alarms.
5. Setup
5.1. Initial Power-Up
Upon initial power-up, the controller will perform a self-test. The display will show the current temperature reading from the primary sensor.
5.2. Basic Configuration
To access and modify parameters:
- Press and hold the SET button for a few seconds to enter the parameter menu.
- Use the Up and Down arrows to navigate through the parameters.
- Press SET to select a parameter and view its current value.
- Use the Up and Down arrows to change the value.
- Press SET again to confirm the new value.
- To exit the menu, press and hold the SET button, or wait for the timeout.
Key parameters to configure include:
- Set Point (SP): The desired temperature for your application.
- Differential (DIF): The temperature difference between cut-in and cut-out.
- Temperature Unit (C/F): Select Celsius or Fahrenheit.
- Defrost Parameters: Interval, duration, and termination methods.
6. Operating the Controller
The ERC213 is designed for intuitive operation, providing precise control over refrigeration cycles.
Figure 6.1: Overview of ERC21X series features, highlighting energy efficiency, unit protection, and simple installation.
6.1. Temperature Control
The controller maintains the set temperature by activating and deactivating the compressor based on sensor readings and configured parameters. It supports various thermostat modes including On/Off, day/night, continuous cycle, and emergency mode.
6.2. Defrost Function
The ERC213 supports natural, electrical, and hot gas defrost methods. It features "defrost on demand" functionality, which optimizes energy consumption by initiating defrost cycles only when necessary. Defrost can be started via a front button, digital input, or time interval.
6.3. Evaporator Fan Management
The controller includes smart evaporator fan management for energy saving, including a fan delay function and fan stop at high evaporator temperature.
6.4. Alarms
The ERC213 provides comprehensive alarm functions to alert users to potential issues:
- High and low temperature alarm
- Sensor failure alarm
- High and low voltage alarm
- Condenser cleaning alarm
- Door open alarm
- External alarm input
7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your ERC213 controller.
- Cleaning: Gently wipe the display and casing with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Connections: Periodically check all electrical connections to ensure they are secure and free from corrosion.
- Ventilation: Ensure that the ventilation openings on the controller are not obstructed to prevent overheating.
8. Troubleshooting
This section provides solutions to common issues you might encounter with your ERC213 controller.
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank | No power supply; faulty wiring. | Check power connections and circuit breaker. Ensure correct voltage. |
| Temperature reading is inaccurate | Faulty sensor; sensor not properly connected or placed. | Check sensor wiring. Verify sensor type and placement. Replace sensor if necessary. |
| Compressor not running | Set point not met; alarm active; compressor protection delay. | Adjust set point. Check for active alarms. Wait for protection delay to clear. |
| Defrost not initiating | Defrost parameters incorrect; sensor issue. | Verify defrost settings. Check defrost sensor. |
