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 The front frame provides a proper finish but can
also be used to secure the controller in place
when using front mounting. In this case, clamps
are not required. Contact Danfoss for details.
