Notes:
(1) the unit of measurement depends on P2
(2) properly set the parameters corresponding to the regulators after setting P2 parameter
(3) if r5 parameter is set at 1, the “energy saving" function and the defrost management will be switched off
(4) the parameter has effect even after an interruption in the power supply that occurs while the device is switched on
(5) the time set by paramenter C2 is counted also when the device is off
(6) the differential of C8 parameter is 2.0°C/4°F
(7) if when the device is switched on, the condenser temperature is already above that established in C7 parameter,
then C8 parameter will not have effect
(8) the value ∆t depends on r12 parameter (r0 if r12 = 0, r0/2 if r12 = 1)
(9) the display restores normal operation when, at the end of the dripping phase, room temperature falls below the
value that locked the display (or if a temperature alarm is triggered)
(10) if P4 parameter is set at 0 or 2, the device will function as if d8 parameter were set at 0
(11) during defrost and dripping, the maximum temperature alarm is absent, provided that it was triggered after defrost
activation.
(12) during activation of the door switch input, the maximum temperature alarm is absent, provided the alarm was
signaled after the activation of the input
(13) the compressor is switched off 10 s after the activation of the input.
