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.
