The ERC 211 is a smart, multipurpose refrigeration controller with temperature and defrost management,
available with 1 relay.
The controller has been designed to fulfil today’s requirements for commercial refrigeration applications.
ENGLISH
1 - Technical Highlights
yEase of use: Four buttons, easy menu structure, pre-installed application solutions ensure superior usability.
ySimple 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.
yUnit 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.
yEnergy efficiency: Defrost on demand, day/night mode and smart evaporator fan management ensure energy
efficiency.

3 - Quick Configuration at Power Up
ySTEP 1: Power on
ySTEP 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.
ySTEP 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 AP5, and thus select the simplified list of parameters, by pressing the UP key
(circular list).
App Description
App 0 None (no preset application)
App 1Medium temperature (4 – 20 °C), without defrost
App 2Medium temperature (2 – 6 °C), with timed natural defrost
App 3Medium temperature (2 – 6 °C), with natural defrost stop on air temperature
App 4Heating Thermostat (20 – 60 °C)
App 5None (no preset application) with simplified parameter list

Quick Configuration at Power Up
ySTEP 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.
