3 Electronic Controller Electronic Controller Operations Overview The SC112N-AC fridge is fitted with a CAREL ECOBOX electronic controller. The electronic controller is visible on the front panel and is housed inside the controller box at the front of the refrigeration system.
SC112N-AC Faceplate Because the electronic controller plays such an important role, it’s helpful to know the parts of the faceplate you may use. Figure 2: Electronic controller faceplate Table 2: Controller faceplate Item Description Alarm Mute (up): Mutes the audible alarm buzzer.
SC112N-AC Running the Fridge Operating The electronic controller will automatically switch the fridge between Day Modes and Night modes depending on use, and into Cold Climate Protection (CCP) mode if necessary (see “Cold Climate Protection (CCP)” on page 10). If the front door (on the electronic controller side) is not opened for four hours, the fridge will automatically enter Night mode and the sign and interior lights will switch off.
SC112N-AC Messages and Alarms Controller The following table explains messages that the electronic controller Display displays, and related alarms. Alarms signal unexpected operational changes in the fridge and can be muted by pressing the Alarm Mute (up) button on the electronic controller faceplate (see page 8).
SC112N-AC Programming the Electronic Controller Parameters The parameter configuration program is set by SKOPE at the factory. A label on the controller box indicates the parameter configuration program number (e.g. the SC112N-AC fridge uses program 089). The electronic controller parameters can be modified using the keypad.
