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.

The access level can be set separately for each
parameter using "KoolProg Software".
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.

The ERC 111 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 "Defrost".
The lower left-button can be supplied with

KoolProg
Software from Danfoss for programming the
ERC-controller via 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.
"KoolProg Software" 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 "KoolProg Software"
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.
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.
"KoolProg Software" is not required for mass
programming.
