BFPR

Bottom Freezer Product Range

April 2004 ESSE-N /A.S. 2

BFPR

BFPR = Bottom Freezer Product Range is the new bottom combi range from Mariestad factoryOuter housing as on previous combi rangeBase and inner lining modified, resulting in:

inner freezer bottom 5 cm lower more volume with identical external dimensions

stainless steel doors with “anti-fingerprint” treatment


BFPRVariants

2-compressor combis with static cooling in refrigerator2-compressor combis with dynamic cooling in refrigerator (DME = Dynamic Mini Evaporator)1-compressor combis with magnetic valve1-compressor combis with magnetic valve and RSD compressor for appliances with energy label A++ (electronic box for compressor now bonded to bottom plate because of reduced space)Bottom freezer always with static cooling


BFPREvaporator Variants

Freezer : tube evaporatorRefrigerator :

Semi-hidden evaporator on most models(higher energy efficiency) DME battery evaporator with 1 fanDME battery evaporator with 2 fans on models with 0°C compartmentHidden (foamed) evaporator on 1-compressor combis with magnetic valve

BFPRSensors

Up to 4 NTC sensors:

refrigerator air sensor white wiringrefrigerator evaporator sensor black wiringair sensor for 0°C compartment white wiring with marking

freezer air sensor brown wiring

Sensors are available as spare parts, and can be replaced

However, 2 or 3 sensors may have a common connector;then they come as a single spare part, so all of them have to be replaced


Semihidden Evaporator

Evaporator must be unfastened for sensor or thermostat replacement - see Service Bulletin 599252769

ERF2000 DMENew start after switch-on

Compressor and fan start simultaneously


ERF2000 DMENormal Function

CUT-IN temperature air sensor : depends on settingCUT-IN temperature evaporator sensor : 2.5°CWhen air sensor and evaporator sensor reach their CUT-IN temperatures

Fan starts immediately Compressor starts with 1-2 min delay

CUT-OUT temperature air sensor : depends on setting When air sensor reaches its CUT-OUT temperature

Compressor stops immediatelyFan stops with 5 min delay


ERF2000 DMENormal Function


ERF2000 DMEDoor Opening

Fan stops immediately

If door open more than 1 min, compressor stops too


ERF2000 DMEDoor Opening


ERF2000 DMEEvaporator Defrost

Normal defrost at every compressor cycle (+2.5°C on evaporator sensor)

“Safety” defrost :after 18 hours accumulated compressor run timeFan ON / compressor OFFFixed duration: 45 min Display shows last temperature before defrost start, or “C” (on some models)

Compressor run time

18 hours


ERF2000 DMEQuick Chill (Coolmatic)

Fan is running continuously

User should open air flap !

Set temperature 2°C

Maximum duration 6 hours

Display shows “C”

ERF2050

ERF2050 is an “extension” of ERF2000 for 2-compressor combis with DME and 0°C compartment

Can drive additional components:0°C-compartment air sensor0°C-compartment fan

Software adapted for function with 0°C compartment


ERF2050Circuit


ERF2050Normal Function

compressor ON, when cooler air sensor OR 0°C-compartment air sensorreach their respective CUT-IN temperatures(N.B.: to ensure correct temperature control in the 0°C compartment, it is not possible to take into consideration the evaporator sensor during normal compressor cycles)

Cooler fan ON, when cooler air sensor reaches its CUT-IN temperature

0°C-compartment fan ON, when 0°C-compartment air sensor reaches its CUT-IN temperature


ERF2050Normal Function

compressor OFF, when cooler air sensor AND 0°C-compartment air sensorreach their respective CUT-OUT temperatures

Fans OFFIf both fans are running, and one of the air sensors reaches its CUT-OUT temperature, the respective fan will stop immediatelyIf only one fan running, and its air sensor reaches the CUT-OUT temperature, the fan will stop after 2 minutes(i.e. fan running last will stop with 2 min delay)


ERF2050Evaporator Defrost

After 4 hours accumulated compressor run time

0°C- compartment fan OFFcooler fan ON

Defrost end when evaporator sensor reaches +3°C


ERF2050Sensor Failure - Refrigerator

Sensor failure is shown if sensor resistance is outside the working range

In refrigerator display:

cooler air sensor failure

evaporator sensor failure

0°C-compartment air sensor failure

EEPROM error

In all these fault cases:Compressor and cooler fan 20 min ON / 30 min OFF0°C-compartment fan OFF


ERF2050Sensor Failure - Freezer

In freezer display:

freezer air sensor failure

Freezer compressor running continuously


ERF2050Service features

Raise temperature in 0°C compartment by 2°C:simultaneously press + and - of the refrigerator untilbeep sounds

Raise temperature in freezer by 3°C:simultaneously press + and - of the freezer untilbeep sounds

ERF2000with LCD on door


Reversing Door Hinge on LCD-on-Door Models

Separate PNCs will be available with R.H. hinge and L.H. door hinge respectively

Reversing possible for service only

Wiring from user interface in top panel to LCD on door has to be re-routed

Prior to performing this operation, new bows (end caps )for the refrigerator door handle have to be ordered !

LCD on DoorON/OFF

Only one main switch: both compressors will start when switched on

To switch of only one compartment, press corresponding + and - simultaneously, wait for count down


LCD on DOOR

New mode: SHOPPING

combination of Coolmatic (refrigerator 2°C for 6 hours)with continous run of freezer compressor for 1 hour


LCD on DoorDEMO Mode

Condition: more than 10°C on both air sensors

Simultaneously pres MODE and ON/OFF for 5 sec long beep

De-activate:same combinationor pull plug
