Parameter remarks

Nr. Remark
1During off-time counters continue to count and output is disabled. At reset command they stop and their value is reset. They are restarted by on command. The minus sign on display ("-") means that you already reset timers.
2The period of each cycle includes on-time + off-time, that is the overall duration of the cycle.
3The "oFF" command disables the ripening functions and enables the storage. The ripening timers continue however to run also if their output is disabled. To restart the ripening timers, please do the "rES" (reset) command. The "on_" command enables the ripening functions without restarting the timers. To begin a new ripening cycle, please do the "rES" command. The minus sign on display ("-") means that you have already reset the timers.
4At the end of the ripening cycle the temperature is set to t5 until the manual reset of the ripening cycle.
5The stop command resets forced operation counter.
6In case of probe control, ethylene timers and settings are not used. You can still activate forced injections. In case of disabled probe, rYY is used to control curtain string motor when curtain is idle.
7To synchronize ethylene injection and ripening start, set dY0 = _d0.
8First ethylene injection is delayed until room temperature reaches _tY. _tY has no effect over following ethylene injections.
9To synchronize the beginning of further ethylene injections and air renews, set dY3=dA3.
10To synchronize the cycles of further ethylene injections and air renews, set dY3=dA3.
11Set by the microcontroller - can be manually overwritten.
12Door operation disables every other keyboard operation.
13The first pressure of push button inside the room - near the door - switches on the light, the second one opens the door, the third one activates the "man in room" alarm.
14During the delay the flashing light is on.
15For your safety, do not modify this parameter. This setting is supposed to be used just in case of emergency or testing.
16No action if the light is switched on from inside the room.
17Curtain operation disables every other operation keyboard operation.
18For safety reason, door operation is disabled when curtain is enabled. Unrolling can be started also by a push button located near the depressure box, inside the room.
19When off, the refrigeration solenoid is steadily on during cooling, as long as overheating is higher then vtL or b3A is off.
20Caution! Low overheating causes liquid return and compressor damage.
21Caution! Short duty cycle reduces valve life.
22Caution! Low overheating causes liquid return and compressor damage.
23Caution! High adaptation speed causes swing in the suction line and damage to the compressor.
24The low temperature differential is fixed, and alarm status stops at 0.2 °C above the set point.
25The high temperature differential is fixed, and alarm status stops at 0.2 °C under the set point.
26Passing from stand-by to on and at power on, there is a 5 second delay spent in a virtual stand-by.
27When keyboard is locked it is possible to read parameters but is not possible to modify them. To exit the lock it is necessary to write the password.

How to ...

How to ... Function
Switch between on and stand-by.Keep pressed B3 button, to activate and deactivate stand-by. In stand-by every output is disabled except light, leds from L1 to L6 blink, timers continue to count.
Program the menu.Keep pressed B6 to enter the menu. Navigate up and down with B2 and B5. Select the submenu by B6. Change the parameter by B2 and B5, press B6 to confirm, or B4 to go back without saving. The changes will have effect after the exit from programming pressing B4 repeatedly. Press B1 to exit immediately without saving any parameter.
Show or change temperature set.Press shortly B6 - the display shows the current set point - change it by B2 and B5, and confirm it by B6. As alternative, enter the menu program as explained above, modify the parameter _t0, then confirm it.
Reset timers.For the resettable controls in the menu program, confirming "rES", then confirming "on_" or "oFF", has the joint effect of resetting timers and going into the enabled or disabled status.
Enter ripening mode.Keep pressed B6+B3. As alternative, enter the menu program as explained above, set the parameter rrH, reset it in case it is a new ripening, then confirm it.
Enter storage mode.Keep pressed B6+B1. As alternative, enter the menu program as explained above, set to oFF the parameter rrH, then confirm it.
Door operation.Push B2 to open, B5 to close, and B1 to stop. If you are inside the room and the door is closed, press B7 once to switch on the light, press again to open the door, and again to trigger the man in room alarm. During door operation display shows "OPE" or "CLO". By default, when the door is open, the light is on and every other output is off. By default, door operation is disabled after the first ethylene injection and before subsequent air renew.
Curtain operation.For safety reason, the curtain can be operated only when the door is fully open and the light is on. To activate the keyboard for the curtain, keep pressed B6+B4, then press shortly B6 or B8 to unroll, B4 to roll, B1 to stop, and again B1 to exit curtain mode. During curtain operation, every output is disabled. The display shows "Cur" with the curtain idle, "Unr" during unrolling, and "rOL" during rolling.
