Dimensions (mm) and Mounting
Electrical Connections
The ERC 213 is a smart, multipurpose refrigeration controller with temperature and defrost management, available with 3 relays.
The controller has been designed to fulfil today’s requirements for commercial refrigeration applications.
Technical Highlights
- Ease of use: Four buttons, easy menu structure, pre-installed application solutions ensure superior usability.
- Simple installation:
High Effect 16 A relay enable direct connection of heavy loads without use of intermediate relay: up to 2 hp compressors depending on its power factor and motor efficiency (greater than 0.65 for 230 V and greater than 0.85 for 115 V).
A wide range of compatible types of sensors and screw connection terminals ensure highly flexible installation. - Unit protection: Special software features like compressor protection from fluctuation in the power supply or from high condensing temperature ensure the safe operation of the unit.
- Energy efficiency: Defrost on demand, day/night mode and smart evaporator fan management ensure energy efficiency.

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 “o61”
The display automatically shows the application selection parameter “o61”. Press SET to select the pre-installed application. The display shows the default value (eg. “AP0” 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. Tip: you can easily move from AP0 to AP6, and thus select the simplified list of parameters, by pressing the UP key (circular list).
- STEP 4: Select sensor type “o06”
The display automatically shows sensor selection parameter “o06”. Press SET to select the sensor type. The display shows the default value (eg. “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.
Quick Configuration via “cFg” Menu
- Press SET for three seconds to access the parameters groups.
- Select “CFg” menu and press SET to enter. The first menu “r12” (main switch) is displayed.
- Switch OFF main switch (r12=0) for changing the pre-installed application.
- Press UP/DOWN to scroll through the parameter list.
- Configure the “o61” parameter to select a pre-installed application
- Press SET to access the “o61” parameter.
- Press UP/DOWN to select an application (AP0= no application selected).
- Press SET to confirm, “o61” is displayed.
- Continue to set the next parameters (“o06” sensor type) in the “cFg” menu.
Basic operation
Adjust the setpoint temperature
Initiate a manual defrost
Initiate a pull down
View an active alarm
Unlock keyboard
- After 5 minutes of no activity, the keypad is locked (if P76=yes).
- When the keypad is locked any button press shows “LoC” in the display.
- Press UP and DOWN buttons simultaneously for 3 seconds to unlock the keyboard. “unl” is displayed for 3 seconds.
