1 - Technical Highlights
y Ease of use: Four buttons, easy menu structure, pre-installed application solutions ensure superior usability.
y 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.
y 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.
y Energy efficiency: Defrost on demand, day/night mode and smart evaporator fan management ensure energy
efficiency.
The ERC 213 is a smart, multipurpose integrated refrigeration controller with temperature and defrost
management, available with 3 relays.
This controller is for Operating temperature sensing control, suitable for refrigeration and heating
applications.
Incorporated control has been designed to fulfil today’s requirements for commercial refrigeration
applications.

3 - Quick Configuration at Power Up
y STEP 1: Power on
y 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.
y 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).
App Description
App 0 None (no preset application)

Quick Configuration at Power Up
y 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.
