## Operation
### Viewing the Set Point
Push theButton - this will display the current Set Point Temperature
### Adjusting the Set Point Temperature
To Adjust the Set Point Temperature
1. Hold theButton for 3 seconds until the display shows the current Set Point and the **°C** or **°F** symbol starts flashing
2. Use the or buttons to change the Set Point Temperature
### Starting a manual Defrost Cycle
Press theManual Defrost Button for more than 2 seconds to start a defrost cycle manually. The Defrost indicator will illuminate
### Programming Mode
The Dixell Controller has several advanced programabble features that can be tailired for individual situtations. In most ases, the default values will suit. However, as this is a commercial unit, we recommend programming the Defrost Cycle to a suitable length and interval to avoid ice build up. If ice is allowed to build up inside the compressor housing, this will negatively affect performance and potentially void warranty.
### Enter Programming Mode
1. Enter the Programming mode by pressing the Button and or buttons for 3 seconds. The **°C** or **°F** symbol will start flashing
2. Select the required parameter using theor buttons
3. When the desired parameter is displayed, press the Button to display the current stored value of the parameter
4. Use theor buttons to change the value of the parameter
5. Press the Button to store the new parameter. This will also move to the next parameter
6. To exit Programming Mode, press the Button and thebutton or wait for 15 seconds without pushing any buttons. This revert the controller.
### Adjusting Parameters
The following parameters can be selected and adjusted in Programming Mode. To adjust any parameter, enter [Programming Mode](#enter-programming-mode) and navigate to the desired parameter
### Adjust Hysteresis
Hysteresis is the allowed differential from the Set Point Temperature before the compressor (cooling) operates. Thus, if the Set Point Temperature is 2°C and the Hysteresis is 2°C then the compressor will operate when the internal temperature reads 4°C, and it will continue to operate until the Set Point Temperature of 2°C is reached. The default hysteresis is 2°C, which is appropriate for most circumstances.
Note: Decreasing the hysteresis can *increase* power consumption
#### To Adjust the Hysteresis \[Hy]
1. Enter [Programming Mode](#enter-programming-mode) and navigate to **Hy** using theor buttons
2. The Differential Range can be adjusted between 0.1-25°C or 1-45°F. The default is 4°C
3. Use theor buttons to change the value of the parameter to the desired Hysteresis
4. Press the Button to store the new parameter. This will also move to the next parameter
#### Adjust Minimum Set Point \[LS]
1. Enter [Programming Mode](#enter-programming-mode) and navigate to **LS** using theor buttons
2. The Minimum Set Point can be adjusted down to -55°C or -67°F. The default is 0°C
3. Use theor buttons to change the value of the parameter to the desired Minimum Set Point
4. Press the Button to store the new parameter. This will also move to the next parameter
#### Adjust Maximum Set Point \[US]
1. Enter [Programming Mode](#enter-programming-mode) and navigate to **US** using theor buttons
2. The Maximum Set Point can be adjusted up to 99°C or °F. The default is 10°C
3. Use theor buttons to change the value of the parameter to the desired Maximum Set Point
4. Press the Button to store the new parameter. This will also move to the next parameter
### Temperature Probe Calibration \[ot]
If there is a large variance between the *displayed* temperature (IE the temperature of the internal temperature probe and the *actual* internal temperature of the kegerator (as measureed by a calibrated thermometer) then the Temperature Offset can be adjusted from -9.9°C to +9.9°C
A Temperature Offset will offset the displayed temperature by the entered amount.
Thus, if the displayed temperature is 2°C but the actual internal temperature is 4°C, and offset of +2°C is required.
Note: In most cases this is not necessary to be adjusted. There will be minor temperature differences in the kegerator due to airflow etc. This may also be pre-adjusted in the factory.
#### To Adjust the Temperature Probe Offset \[ot]
1. Enter [Programming Mode](#enter-programming-mode) and navigate to **ot** using theor buttons
2. The Probe Calibration Offset can be adjusted from -9.9°C to +9.9°C. This may be at a value other than 0°C due to factory calibration.
3. Use theor buttons to change the value of the parameter to the desired Probe Calibration Offset
4. Press the Button to store the new parameter. This will also move to the next parameter
#### Change Display Units (Celsius/Fahrenheit) \[CF]
1. Enter [Programming Mode](#enter-programming-mode) and navigate to **CF** using theor buttons
2. Use theor buttons to cycle the display between Cesius (°C) and Fahrenheit (°F)
3. Press the Button to store the new parameter. This will also move to the next parameter
### Defrost Cycle Adjustments
The Grand Deluxe 3 range are commercial units. As such, they have very powerful compressors. It is important that an adequate Defrost Cycle is programmed in to ensure that ice does not build up on the cooling fins. Failure to program an adequate defrost cycle can reduce the performance of the unit and may also void warranty.
#### Defrost Interval (interval between defrost cycles) \[id]
* Enter [Programming Mode](#enter-programming-mode) and navigate to **id** using theor buttons
* The Defrost Interval can be adjusted from 0-99 hours. The default is 6
* Use theor buttons to change the value of the parameter to the desired Defrost Interval
* Press the Button to store the new parameter. This will also move to the next parameter
#### Maximum defrost length \[Nd]
* Enter [Programming Mode](#enter-programming-mode) and navigate to **Nd** using theor buttons
* The Maximum defrost length can be adjusted from 0-99 minutes. The default is 20
* Use theor buttons to change the value of the parameter to the desired Defrost length
* Press the Button to store the new parameter. This will also move to the next parameter
