(1) the unit of measurement depends on parameter P2
(2) set appropriate regulator parameters after altering parameter P2
(3) if parameter u1 is set to 3, the service controlled by the fourth output will be compressor 2: compressor 1 and compressor 2 are referred to as "compressor"; compressor 2 operates in parallel with compressor
1, regardless of parameter C9
(4) the parameter is even effective after power supply interruption, such as when the device is switched on
(5) the time period established by the parameter is counted even while in stand-by mode
(6) if parameter C1 is set to 0, the cabinet probe error resolution delay will be 2 minutes in any case
(7) the parameter differential is 2.0°C/4°F
(8) if, on device start-up, the condenser temperature is already above that established by parameter C7, parameter C8 will have no effect
(9) the device stores the defrost interval count every 30 minutes; altering parameter d0 has the effect of concluding the previous defrost interval or manual defrost activation
(10) the display is restored to normal operation when, the evaporator fan stop is concluded, the cabinet temperature drops below that which blocked the display (or if a temperature alarm occurs)
(11) if parameter P3 is set to 0 or 2, the device will operate as though parameter d8 was set to 0
(12) if, on defrost activation, the compressor on duration is less than the time established by parameter dA, the compressor will remain on for the fraction of time required to complete it
(13) if parameter P3 is set to 0, the device will operate as though parameter A0 was set to 0, but will not record the alarm
(14) if parameter P4 is set to 0 or 3, the device will operate as though the parameter was set to 0, but will not record the alarm
(15) during defrosting, drip draining and ventilator fan stop, there are no temperature alarms, if said occur following defrost activation
(16) there is no maximum temperature alarm while microport input is enabled, if occurring after input activation
(17) if parameter P3 is set to 0, the device will operate as though parameter F0 was set to 2
(18) the compressor is switched off 10 s after activation of the input; if the input is activated during defrosting or evaporator fan stop, activation will have no effect on the compressor
(19) the device records alarms occurring after the time established by parameter i2; if parameter i2 is set to -1, the device does not record the alarms
(20) ensure that the time established by parameter i7 s less than that established by parameter i9
(21) in order to avoid damage to the service connected, modify the parameter while in stand-by mode
(22) if the fourth output terminals are connected to the fourth input terminals of several devices, it will be possible to synchronise defrosting (providing that in each device, parameter P4 is set to 3, that parameter i5 is
set to 1 and parameter u1 is set to 7); in this case, drip-drain duration counting starts when defrosting of the last device is concluded
(23) it is recommended that parameter d7 for each device be set to the same value (different from 0 min); similarly, it is recommended to set parameter F3 for each device to the same value
(24) if parameter u2 is set to 0, switching off the device may cause switching off of the cabinet light or the auxiliary output (the service will remain off on subsequent switching on of the device); if parameter u2 is set
to 1, switching off the device does not cause switching off of the cabinet light or the auxiliary output (the service remains on on subsequent switching on of the device).
The device must be disposed of in accordance with local regulations pertaining to the collection of electrical and electronic appliances.
6 = TURNING ON THE AUXILIARY OUTPUT - the auxiliary output will be turned on (only if u1 = 2, until the input is deactivated)
7 = SWITCHING OFF THE DEVICE - the device will switch to stand-by mode (until the input is deactivated)
type of multifunction input contact (only if P4 = 3)
0 = NA (input active with contact closed)
1 = NC (input active with contact open)
if i5 = 4, delayed multifunction input alarm notification (only if P4 = 3)
if i5 = 5, delayed multifunction input deactivation compressor delay (only if P4 = 3) (20)
number of multifunction input alarms such as to cause device block alarm (only if P4 = 3 and i5 = 5)
0 = no alarm
time that must elapse without multifunction input alarms so that the alarm counter is zeroed (only if P4 = 3 and i5 = 5)
DIGITAL OUTPUTS
service controlled by the fourth output (21)
0 = CABINET LIGHT - in this case, the important factors are: the key
, parameters i0, i5 and u2
1 = DEMISTING HEATER - in this case, the important factors are: the key and parameter u6
2 = AUXILIARY OUTPUT - in this case, the important factors are: the key , parameters i5 and u2
3 = COMPRESSOR 2 - in this case, the important factor is parameter C9
4 = ALARM OUTPUT - the output is activated during an alarm and during an error; in this case the important factors are parameters u3 and u4
5 = DOOR ELEMENT - in this case the important factor is parameter u5
6 = EVAPORATOR VALVE - in this case the important factors are parameters u7 and u8
7 = DEFROST SYNCHRONISATION - the output works in parallel with the defrost output; in this case the important parameter is factor i5 (22) (23) enabling cabinet light or auxiliary
enables manual switching on/off of the cabinet light or auxiliary output while in stand-by mode (only if u1 = 0 or 2) (24)
1 = YES
alarm output polarity (only if u1 = 4)
0 = disabled during normal operation (the contact between terminals 6 and 7 will be open) and activated during an alarm and during an error (the contact between terminals
6 and 7 will be closed)
1 = activated during normal operation (the contact between terminals 6 and 7 will be closed) and disabled during an alarm and during an error (the contact between terminals
6 and 7 will be open)
enable alarm output deactivation with muting of buzzer (only if u1 = 4)
1 = YES
cabinet temperature above which the door element is switched off (only if u1 = 5) (7)
demisting heating duration (only if u1 = 1)

evaporator valve contact type (only if u1 = 6)
0 = NA (valve active with contact closed)
1 = NC (valve active with contact open)
