Bigger internal capacity

The Convenience range offers an extra 10-15% usable storage capacity compared to the actual models with the same external dimensions.

This has been obtained with Full height side panelsRemoving the conventional top and leaving only a front panelReducing the plinth to 5 cmOptimizing the internal layout of the appliances

Models with Electronic ControlERF2021 + Dual Smart

The electronic models are equipped with a new electronic control, consisting of:Power Board ERF2021User Interface “Dual Smart”It offers quasi-independent temperature control in the 2 compartments of an 1-compressor combi, using separate temperature sensors and an “intelligent” balance heaterThis type of electronic control can be used on models with staicfreezer too

Power Board ERF2021

User Interface with LCD

Dual Smart

2 rotary temperature selectors (potentiometers), with max-middle-min settings corresponding approximately to:

+8 +5 +2°C in refrigerator -16 -18 -24°C in freezer

after 10 seconds without any action, the display will revert to ambient temperature

Switch off Apliance

Press ON/OFF for about 1 secCountdown ”3-2-1”Display blank

Sensor Failure

If the resistance of one air sensor ist outside the working range, this will be shown as below:

Compressor : 40 min ON / 40 min OFFA faulty evaporator sensor will not be shown to the user

Location of Balance Heater

Balance heater not replaceable (under fridge evaporator)

Wiring to Balance Heater

Balance Heater16 W

The balance heater is controlled by triac ACS2 on the power boardBy using phase cutting, the heater can be used at variable powerThe software will determine the power level based on ambient temperature, and of actual demands from the 2 compartments, as measured by the air sensorsThis ensures a good control at ambient tempeartures as defined for SN/N/ST climatic class (10-38°C)In case of heater failure, the appliance will work more or less satisfactorily (i.e. like a conventional 1-compressor combi) at ambient temperatures above 16°C (N/ST)

Defrost

First defrost routine: 5 hours after power-on, or after power reset

The following defrost routines are initiated after 14, 30 or 71 hours - depending on a series of factors: activation of fast freezing, accumulated door opening, compressor duty cycle, time limit reached at previous defrost

The defrost routine will start after the next compressor cut-out (if the compressor continues to run for more than 2,5 hours, it will be forcibly stopped)

Fan off at 2 min after start of defrost routineHeater on 5 min after start of defrost routine

Minimum defrost time: 20 min

Defrost

Under normal conditions, the defrost heater will be cut off by the fixed bimetal thermostat, which opens at +8°C

After the minimum defrost time of 20 minutes has elapsed, the electronic control starts checking if the thermostat has opened

Once this has happened, the heater triac will also switch off the supply to mark defrost end

Compressor start 5 min after defrost end

Fan start 3 min after compressor start

Defrost

Safety:

Temperature limit + 40°C (thermostat in series with the other side of the heater

Time limit 60 min

Service Mode
