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.
The ERC 214 is a smart, multipurpose integrated refrigeration controller with temperature and defrost
management, available with 4 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.
