How do I change the temperature setpoint on the XR06CX?

Press the SET key for more than 2 seconds to enter setpoint change mode, then the setpoint value will display with the °C or °F LED blinking. Use the up or down arrow keys to adjust the value, and press SET again or wait 10 seconds to save the new setpoint.

2

What does the 'P1' alarm message mean and how do I fix it?

The 'P1' message indicates a room probe (thermostat) failure. When this alarm occurs, the compressor output will operate according to the 'Cy' and 'Cn' parameters. Check the probe connections before replacing the probe, as the alarm should automatically stop within seconds after the probe returns to normal operation.

3

How do I start a manual defrost cycle?

Press the DEF key for more than 2 seconds to start a manual defrost. The defrost will begin if the conditions allow it.

4

What is the anti-short cycle delay and what is the default setting?

The anti-short cycle delay (AC parameter) is the minimum interval between the compressor stop and the following restart, which prevents the compressor from cycling too quickly. The default setting is 1 minute, and it can be adjusted from 0 to 50 minutes.

5

How do I lock the keyboard to prevent accidental changes?

Keep the Aux and down arrow keys pressed together for more than 3 seconds until the 'OF' message is displayed. The keyboard will then be locked, and pressing any key for more than 3 seconds will display the 'OF' message.

6

How do I use the Hot Key to copy settings from one controller to another?

To upload settings to the Hot Key, turn the controller ON, insert the Hot Key, press the down arrow key until 'uP' appears followed by a flashing 'Ed', then press SET to confirm. To download to another controller, turn it OFF, insert the programmed Hot Key, then turn it ON — the parameters will automatically load and the controller restarts after 10 seconds. An 'Er' message indicates a failed transfer. (Page 2)

    • |6.5 HIDDEN MENU| |---|

    In case of fault in the thermostat probe the start and stop of the compressor are timed through parameters “Cy” and “Cn”.

    The hidden menu includes all the parameters of the instrument. HOW TO ENTER THE HIDDEN MENU

  • 1. Enter the Programming mode by pressing the SET+ keys for 3s (“°C” or “°F” LED starts blinking).

  • 2. Released the keys, then push again the SET+ keys for more than 7s. The L2 label will be displayed immediately followed from the Hy parameter. NOW YOU ARE IN THE HIDDEN MENU.

  • 3. Select the required parameter.
  • 4. Press the “SET” key to display its value
  • 5. Use or to change its value.

  • 6. Press “SET” to store the new value and move to the following parameter. To exit: Press SET+ or wait 15s without pressing a key.

    • 4 DEFROSTTwo defrost modes are available through the “td” parameter:

  •  td=EL  defrost through electrical heater (compressor OFF)
  •  td=in  hot gas defrost (compressor ON). Other parameters are used to control the interval between defrost cycles (id) ), its maximum length (Md) and two defrost modes: timed or controlled by the evaporator’s probe. At the end of defrost dripping time is started, its length is set in the dt parameter. With dt=0 the dripping time is disabled. 5 FANS With FC parameter it can be selected the fans functioning:
  •  FC=cn  will switch ON and OFF with the compressor and not run during defrost
  •  FC=on  fans will run even if the compressor is off, and not run during defrost After defrost, there is a timed fan delay allowing for drip time, set by means of the “Fd” parameter.
  •  FC=cy  fans will switch ON and OFF with the compressor and run during defrost
  •  FC=oY  fans will run continuously also during defrost.

  • NOTE1: if there aren’t any parameter in L1, after 3s the “nP” message is displayed. Keep the keys pushed till the L2 message is displayed.
  • NOTE2: the set value is stored even when the procedure is exited by waiting the time-out to expire.

    ###### HOW TO MOVE A PARAMETER FROM THE HIDDEN MENU TO THE FIRST LEVEL AND VICEVERSA.

    Each parameter present in the HIDDEN MENU can be removed or put into “THE FIRST LEVEL” (user level) by pressing SET+ . In HIDDEN MENU when a parameter is present in First Level the decimal point is on.

    |6.6 TO LOCK THE KEYBOARD| |---|

    An additional parameter “FS” provides the setting of temperature, detected by the evaporator probe, above which the fans are always OFF. This is used to make sure circulation of air only if his temperature is lower than set in “FS”

  • 1. Keep pressed for more than 3s the and keys.

  • 2. The “OF” message will be displayed and the keyboard will be locked. If a key is pressed more than 3s the “OF” message will be displayed.

  • 8 DIGITAL INPUTS (ONLY XR03CX) The free voltage digital input is programmable in different configurations by the “i1F” parameter.

    • |8.1 DOOR SWITCH (IF=DO)| |---|

    It signals the door status and the corresponding relay output status through the “dC” parameter: no = normal (any change); Fn = Fan OFF; CP = Compressor OFF; FC = Compressor and fan OFF. Since the door is opened, after the delay time set through parameter “di”, the door alarm is enabled, the display shows the message “dA” and the regulation restarts if rd = y. The alarm stops as soon as the external digital input is disabled again. With the door open, the high and low temperature alarms are disabled.

    |8.2 EXTERNAL ALARM (IF=EA)| |---|

    As soon as the digital input is activated the unit will wait for “di” time delay before signalling the “EA” alarm message. The outputs status don’t change. The alarm stops just after the digital input is deactivated.

    |8.3 SERIOUS ALARM (IF=BA)| |---|

    When the digital input is activated, the unit will wait for “di” delay before signalling the “CA” alarm message. The relay outputs are switched OFF. The alarm will stop as soon as the digital input is deactivated.

    |8.4 START DEFROST (IF=DF)| |---|

    It starts a defrost if there are the right conditions. After the defrost is finished, the normal regulation will restart only if the digital input is disabled otherwise the instrument will wait until the “Md” safety time is expired.

    |8.5 INVERSION OF THE KIND OF ACTION: HEATING - COOLING (IF=HC)| |---|

    This function allows to invert the regulation of the controller: from cooling to heating and viceversa.
