Danfoss ERC 213 Electronic Refrigeration Control

Installation Guide

1. Technical Highlights

Ease of use: Four buttons, easy menu structure, pre-installed application solutions ensure superior usability.
Simple installation: High performance 16 A relay enables direct connection of heavy loads, such as 2 hp compressors, without use of intermediate relays. A wide range of compatible types of sensors and screw connection terminals ensure high flexibility in installation.
Unit protection: Special software features like compressor protection from fluctuation in power supply or from high condensing temperature ensure the safety operation of the unit.
Energy efficiency: Defrost on demand, day/night mode and smart evaporator fan management ensure energy efficiency.

4. Electrical connections

[Diagram showing electrical connections for power supply, sensors, and digital inputs/outputs.]

Note: 2L and 3L must be connected to the same phase.

Power connectors: wire size = 0.5 - 1.5 mm², max. tightening torque = 0.4 Nm

Low voltage signal connectors: wire size = 0.15 – 1.5 mm², max. tightening torque = 0.2 Nm

5. Quick configuration at power up

STEP 1: power on
STEP 2: select the quick configuration menu: Within 30 seconds of power on, press "<" BACK for 3 seconds. The main switch "r12" is automatically set to OFF.
STEP 3: select pre-installed application: The display automatically shows the application selection parameter "061". Press SET to select the pre-installed application. The display shows the default value (e.g., "APO" flashing). Choose the application type by pressing UP/DOWN and press SET to confirm. The controller presets parameter values according to the selected application and does not hide relevant parameters.
STEP 4: select sensor type: The display automatically shows sensor selection parameter "006". Press SET to select the sensor type. The display shows the default value (e.g., "n10" flashing). Choose sensor type by pressing UP/DOWN (n5=NTC 5 K, n10=NTC 10 K, Ptc=PTC, Pt1=Pt1000) and press SET to confirm. Note: All sensors must be the same type.
STEP 5: configure DO2 output: The display automatically shows the "o71" parameter to configure "DO2" output. Select required configuration (DEF or Lig or ALA) as per the application and press SET to confirm. The display returns to normal display mode and the control is started.

6. Quick Configuration via "cFg" Menu

Press "SET" button for 3 seconds to access the parameter menu (display will show "cFg").
Enter "CFg" menu by pressing "SET" button (display will show first parameter "r12" main switch).
Select "r12" by pressing "SET" button again and set the main switch to "OFF" (r12=0).
Press back button ("<") to come back to 'CFg" menu.
Press DOWN button to scroll through the "cFg" menu parameter list.
Open the "061 application mode" and select needed application mode (Press SET).
Open the "007 Cooling/Heating" and select needed function and press "SET" (applicable only for APO and AP5).
Open the "006 Sensor type" and select the temperature sensor type used (n5=NTC 5 K, n10=NTC 10 K, Ptc=PTC, Pt1=Pt1000)- (Press "SET").
Open the "071 DO2 configuration" and select the function associated to DO2 output and press "SET".
Open the "002 DI1 Configuration" and select the function associated to digital input 1 (Press "SET").
Open the "037 DI2 Configuration" and select the function associated to digital input 2 (Press "SET").
Navigate back to parameter "r12 Main switch" and set it in "ON" position to start control.
Go through other parameters default settings and change wherever needed.
