Password protected
Temperature control for refrigeration appliances.
Front panel mounting.
The latest generation CPU, plenty of memory
and high-end electronic components allow for
a uniquely versatile software. Three separate
password-protected user levels can be used to
control more than 300 different parameters to fit
all individual requirements.
R290/R600a end-use applications employing in
accordance to EN/IEC 60335-2-24, annex CC and
EN/IEC 60335-2-89, annex BB;
Glow wire according to EN/IEC 60335-1;
IEC/EN 60730;
UL60730;
NSF,
CQC;
GOST R 60730.
The access level can be set separately for each
parameter using "Software tool".
There are three levels of access 1, 2, 3:
- level 1 is for shop access;
- level 2 for technicians;
- level 3 for OEMs.
The access levels cannot be set using the buttons.
Passwords for the different levels can however be
altered for the level of access you have,
e.g. a level 2 user can change the password for
level 1 and level 2 but not level 3.

Display
Buttons
The ERC 112 is an electronic refrigeration
controller with an LED display especially
developed for bottle coolers and commercial
fridges and freezers. It is particularly suited for
OEM customers where time, easy and reliable
installation and high quality need to go hand in
hand with flexibility.
The display can be ordered in red or blue.
The controller is available with the upper left
button as "ECO" or "Defrost".
The lower left-button can be supplied with
"Light", "Stand by" or "Super chill".
Clips Are used to secure the controller in place in the
case of rear mounting. They are not used with
front mounting.
There are two identical clips, one placed on
either side of the controller.
Front frame
Controller without front frame Front frame with/without name/logo
At front mounting place the wired controller in
the hole. Then press the front frame in position.
The plastic lugs locks hereby the controller.

Control temperature sensor
There are different lengths.
Defrost temperature sensor
Should be mounted on the evaporator.
Condenser temperature sensor
Should be mounted on the condenser.
Light sensor
Is optional and is used to measure the level of
ambient light around the cabinet so that night
and day "Economy", "Normal" modes of operation
can automatically be set, as well as the brightness
of the display.
Motion sensor
Should be mounted on the cabinet front.
Door sensor connector cable
Is optional and is a connector and cable with
spade terminals compatible with door contacts
used in refrigeration applications.

Software for PC
USB gateway
USB programming key
Docking station
Software tool
Software from Danfoss for programming the
ERC 112 via a USB gateway and a PC rather than
with the front panel buttons.
USB gateway
The USB Gateway is a laboratory tool, offering
fast and easy programming of any ERC
controller connected directly to the PC.
"Software tool" installation kit is provided for the
PC. The gateway is standard inventory for OEM
labs.
Programming an individual unit in a
laboratory
The USB key requires "Software tool" running on
a PC. It enables parameters to be set in real time
and an array of status information to be read
(bidirectional connection).
Once the desired settings have been
determined, a specific parameter file is saved to
the USB key for later mass programming through
the docking station.
Mass programming on an assembly line:
The docking station is used for high volume
programming of ERC controllers, for example on
an assembly line. The docking station is a
write-only device.
The USB key, is to be inserted into the docking
station. The settings are then loaded into each
successive controller in a matter of seconds.
"Software tool" is not required for mass
programming.

assembly line you may opt for software controlled set point adjustment
(speed improvement)
"SPr"
Min. 0.0
Max. 1.0
Default 0.5
Current set point adjustment value diF * SPr
The default value is set to 0.5 and the parameter is hidden by default.
"Spr" defines the position of the set point in relation to cut-in and cut-out.
"Spr=0,5" sets the set point mid between cut-in and cut-out.
"Spr=0" sets the set point at the cutout. "Spr=1" sets the set point at cut-in.
"diF"
Min. 0.0 K
Max. 20.0 K
Default 2.0 K
Thermostat differential
This defines the difference between the cut-out and the cut-in.
The desired temperature is determined by "SPr" and "diF".
"HSE"
Min. -100.0°C
Max. 200.0°C
Default 50.0°C
Upper limit of thermostat set point
Define the temperature range limit of the controller.
Once set, the desired temperatue (set point) can not go above "HSE" or
below "LSE".
"LSE"
Min. -100.0°C

When the compressor is OFF, and "FoC" or "FSC" are not zero, the fan
runs in cycles according to "FoC" and "FSC".
Example: "FoC=120" [sec] and "FSC=120" [sec] means that the fan runs
for half the time when the compressor is OFF. When the compressor is
