Dixell Digital Controller operation & DiagnostiC guiDe

The operating temperature range is preset at the factory according to the table below and can be

adjusted up or down within the limits shown.

To see the set point - push and immediately release

the SET button. The set point will be displayed.

To return to normal visualization - Push and

immediately release the SET button or wait ve seconds.

To change the set point - push and hold the SET button for more than two seconds. When the º F display begins ashing, push the up arrow or down

arrow buttons to adjust the set point to the desired

value.

To save the new set point and return to the temperature display mode - push and release the SET

button or wait ten seconds.

† Adjusting the factory set point will also adjust the operating range by the same amount * To determine a Two Zone Cooler refrigeration conguration, refer to the 2 digits immediately preceding the

rst hyphen of the model number found on the cooler data tag. These 2 digits will always be BW (Beer/ White Wine), BR (Beer/Red Wine), or WR (White Wine/Red Wine). Example: MODEL: BB60BR-L1-

XS(LR).

The refrigerator is programmed to automatically

defrost four times daily for approximately twenty minutes. During defrost, the fan inside the cooler

will remain on and the refrigeration system will

turn off. To initiate defrost manually, push and hold the DEFROST button for more than two seconds.

The thermostat controller does not have an “OFF”

function. To turn refrigerator off, the unit must be

unplugged or power to the electrical branch circuit

has to be turned off via a circuit breaker or switch.

Models BB, ND, LP, FV, MFV, UCR Self Contained Coolers using Dixell digital thermostat controller

The thermostat control probe wire connector may become disconnected when the compressor

compartment cover and/or grill are removed. This will result in thermostat P1 code. While the P1 code is ashing the compressor will cycle 5 minutes on and 5 minutes off and may cause icing of the evaporator coil.

Service calls to reconnect the probe wiring are not

covered by factory warranty.

Controller error codes:

➢ P1- Room Probe Failure

• Check to make sure the probe is connected to the controller

• Check the probe resistance (see “Checking the probe resistance” below)

➢ P2- Evaporator Probe Failure

• This error should only occur on MFV units. Verify that the unit is an MFV model.

• Check to make sure the probe is connected to the controller

• Check the probe resistance (see “Checking the probe resistance” below)

➢ dF- Indicates that the unit is in defrost

• Normal Scheduled defrosts can last up to 20 minutes at the factory default values

• If abnormal defrosts are suspected see “Resetting the program to factory default settings” below

➢ HA- Maximum Temperature Alarm

• The box temperature has exceeded the 75° maximum for more than 30 minutes

• See diagnostic flow charts below

➢ LA- Minimum Temperature Alarm

• The box temperature has deceeded the 25° minimum (-15° for MFV) for more than 30 minutes

• See diagnostic flow charts below

Checking the controller set point:

➢ Press the set button once to display the controller set point. Press again to return to the temp display.

Changing the controller set point:

➢ Hold the SET key for 3 seconds, release, and use the arrow keys to change the set point. The set point can be

changed from 33° to 65° on coolers and 0° to 28° on MFV's

• Factory Default set points are as follows: MFV 10°, Beer 34°, White Wine 50°, Red Wine 60°

• There is a 5° (8° for MFV) differential between cut in and cut out temps. If the controller set point is 35°

the range will be 35° to 40°. (MFV controller set point 10°, range will be 10° to 18°)

Checking the probe resistance:

➢ Verify the probe resistance is accurate at the box temperature

• Use a calibrated thermometer to check the cooler's temperature at the evap inlet where the probe is located

• Disconnect the probe from the controller

• Use a calibrated Ohm meter to measure the resistance of the probe at the box temperature

• The resistance of the probe should match the associated box temperature of the following table

➢ Fill a cup full of ice water (use a lot of ice), put the probe into the ice bath, stir for 1 minute, then measure the

resistance with a calibrated Ohm meter. Make sure to keep the probe in the center of the cup.

• The probe should have 27,280 Ohms of resistance in the ice bath. Replace the probe if it is not within 2

degrees Ohms range from Table 1 above.

➢ After verifying the probe resistance to the box temperature, plug the probe into the controller and check the

temperature displayed

• The controller should display the associated temperature of Table 1 above when compared to the

resistance measured

Note: the probe cannot be plugged into the controller when measuring resistance

➢ Fill a cup full of ice water (use a lot of ice), put the Ohm verified probe into the ice bath, stir for 1 minute.

Make sure to keep the probe in the center of the cup.

• The controller should display 32°

Checking the controller compressor relay:

Does the controller relay open and close at the operating range specified on the data tag?

• If the controller is calling for cooling, the compressor relay (terminals 8 & 9) will have continuity

Note: there is a 1 minute anti-short cycle delay programmed into the controller. The snowflake will flash on the display indicating this delay. When the snowflake is solid, the controller is calling for cooling and the relay will be closed.

Resetting the program to factory default settings:

➢ Hold the SET and DOWN ARROW for 3-4 seconds until the display changes and release; the display will

either read “rE” or “d2” and the °F symbol will be flashing. Immediately hold the SET and DOWN ARROW for another 7-8 seconds until the display changes to L2, release the buttons and Hy will be displayed; this is the controllers hidden menu where you can set the parameters of the chart below.

Note: The SET and DOWN ARROW must be pressed at the same time. If one is accidentally released, the process will need to be restarted. Note: If no keys are pressed, the hidden menu access will time out after 15 seconds and revert to normal operation.

• Use the arrow keys to scroll to the desired set point

• Press set to access the value

• Use the arrow keys to change the value

• Press set again to lock in the value
