Danfoss ERC 211 Electronic Refrigeration Control Installation Guide

Danfoss ERC 211 Electronic Refrigeration Control

Introduction

The ERC 211 is a smart multipurpose

refrigeration controller with temperature and defrost management, available with 1 relay.
The controller has been designed to fulfill today’s requirements of commercial refrigeration applications.

Technical Highlights

• Ease of use: Four buttons, easy menu structure, pre installed application solutions ensure superior usability.
• Simple installation: High performance 16 A relay enable 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 and day/night mode ensure energy efficiency

Dimensions (mm) and Mounting

Electrical Connections

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

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 AP5, 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.
