SETUP MENU While the machine is in standby, press MENU and select the SETUP menu using the INCREASE and DECREASE keys: Menu 08 Setup When you press ENTER, you will be asked to enter the necessary password to access the setup submenus. Set Password 0 Select your password using the INCREASE and DECREASE keys and press ENTER. The default password is -19. If your password is correct, the first submenu will be displayed; otherwise you will exit from the menu. Press MENU to return to the Home Menu.
16.1. Parameters Press ENTER to access the parameter setup mode. The first line of the display shows the first parameter with its current value and its unit of measurement. P01 = -5°C Use the INCREASE and DECREASE keys to scroll through all the control parameters. Press ENTER to access the parameter change: P01 = -5°C -5 Use the INCREASE and DECREASE keys to change the parameter value. Press ENTER to confirm. Press the MENU key to go back to the Home Menu. 16.2.

Press the INCREASE key to reset the parameters. 16.4. Fan speed adjustment Press ENTER to access the fan speed adjustment function, where you can select the minimum and maximum speed and the minimum speed during the dehumidification phase (present only if the humidity probe has been selected).
. STEAM GENERATOR There is an output available to activate a steam generator. This output will be switched on for every phase requiring the humidification phase, apart from any P32 parameter value (selection of the humidification mode). If parameter P72 has value 0, opening the door will result in no effect; if parameter P72 has value 1, when the door is opened the steam generator will be switched off.
T On P33 T On P33 Inizio fase Where T On is the preset number of minutes of activation. Humidity injection is inhibited if the temperature in the cell is lower than the value determined by parameter P31 for both the automatic and manual cycles. 18.2. Humidification with humidity probe You can enable the humidity probe by setting parameter P32 = zero. The humidifier output switching on/off follows the following curve.
bp ist is the proportional adjustment band (parameter P39) is the humidification adjustment hysteresis (parameter P37) This function is always active during the awakening, rising and slowing down phases, but it can also be enabled for the stop and preservation phases by way of parameter P36. Regarding the manual cycle, the humidification is only active during the heating and climatization phase. In case the temperature in the cell is lower than parameter P31, the humidification function will be disabled.
19. DEHUMIDIFICATION This function is always active when the humidity probe is enabled. By setting parameter P32 = zero, the humidity probe will be enabled. Dehumidification occurs by using the solenoid valve and the compressor switching on or by setting parameter P71 = 2, when output K3 can be used to control a humidity extraction fan or a dehumidifier.. 19.1. Dehumidification with compressor This type of dehumidification is possible when parameter P71 is different from 2.

19.2. Dehumidification without compressor If parameter P71 is set at 2, when the humidity probe exceeds the preset setpoint output K3 is activated for the dehumidification, as illustrated in the graph below.

20. CELL TEMPERATURE ADJUSTMENT Refer to the following graphic for the resistance and compressor switching on/off. Both compressor and resistance activation are always enabled for all phases.
Compressor activation may be enforced at the beginning of the awakening and rising phases; the duration of such enforced activation is determined by parameter P29. Compressor activation is subject to the safety times (parameters P26, P27 and P28) 21. SOLENOID VALVE Only present if P71 = 0. When P71 = 0, P44 must be configured correctly.
23.2. Phase cut control (P45 = 1) Refer to the following graphic regarding the fans.
• alternatively, when the evaporator probe is higher than parameter P60. All defrost cycles will be interrupted when passing from the preservation phase to the awakening phase of an automatic cycle. At the end of the defrost cycle, you must wait for the end of the dripping time (parameter P63) before switching the compressor on, and for the end of the fan stop time (parameter P63+P64) before switching the fans on.
