(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 compressor1, 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 isset 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 setto 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).
