Paragon ERC 2 Electronic Controller for Self Contained Cases
The ERC 2 Electronic Refrigeration Control is a
microprocessor-based electronic controller designed to
control both the temperature and the defrost functions
of a commercial refrigeration unit. It can be powered by
120, 208 or 240 VAC (50 or 60Hz). The control comes
with four relay outputs: compressor, defrost, evaporator
fan and alarm.
The ERC 2 includes a digital display module that
provides readout of the temperature, time and built-in
diagnostics. The display module can be mounted locally
or remotely from the unit and it contains a touch
keypad for simple programming. For defrost control, the
unit uses a real time clock.
This control is NSF certified and it can be applied to
many different commercial refrigeration applications like
reach-ins, walk-ins, refrigerated cases or other different
products where accurate control of refrigerated space
and defrost cycles is required.

and repeatability
FCC COMPLIANCE*
This device complies with CFR 47, Part 15, Class A FCC
Requirements. Operation is subject to the following
two conditions (1) This device may not cause harmful
interference and (2) This device must accept any
interference received, including interference that may
cause undesired operation.
CANADIAN COMPLIANCE*
This digital apparatus meets all of the Industry Canada,
ICES-003, Class A requirements (Canadian Interference-
Causing Equipment Regulations).
* Note: these compliance apply to NEMA 1 enclosed
models only. All modular units are the responsibility of
the purchaser to obtain the compliance.
OPERATION AND FUNCTIONS
The ERC 2 features a simple way to program and
operate. Four buttons on the display module allow the
user to scroll through the functions and set the desired
parameters. A manual defrost button is used to initiate
the defrost cycle at any time.
There are two different levels of security to access the
programming features. The first one will allow the
change on the time-of-day and the setpoint
temperature (cut-out). The other level will allow access
to the other parameters.
The programmable parameters are:
