3 USER INTERFACE

3.1 Preliminary notes

Operating statuses:

- “on” status (the device is powered and is on; utilities

may be on

- stand-by” status (the device is powered but is switched

off via software; utilities are off

- the “off” status: the device is not powered; utilities are

off.

Hereafter, if the POF parameter is set to 0, with the word

“switch-on” means the passage from “off” status to “on”

status; the word “switch-off” means the passage from “on”

status to “off” status.

If the POF parameter is set to 1, with the word “switch-on”

means the passage from “stand-by” status to “on” status;

the word “switch-off” means the passage from “on” status

to “stand-by” status.

When the power is switched back on, the device displays the

Notes:

(1) the unit of measurement depends on P2

(2) properly set the parameters corresponding to the regulators after setting P2 parameter

(3) the temperature associated with regulation and the temperature alarms is the CPT temperature; the formula to calculate the CPT temperature is as follows:

CPT temperature ={[(parameter P7)x(inflowing air temperature)]+[(100-parameter P7)x(outflowing air temperature)]:100}

(4) if r5 parameter is set at 1, the “energy saving" function and the defrost management will be switched off; see also F1 parameter

(5) the parameter has effect even after an interruption in the power supply that occurs while the device is switched on

(6) the time set by paramenter C2 is counted also when the device is off (“stand-by” status)

(7) the differential of parameter is 2.0°C/4°F

(8) 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

(9) the value ∆t depends on r12 parameter (r0 if r12 = 0, r0/2 if r12 = 1)

(10) the display restores normal operation when, at the end of the dripping phase, room temperature or CPT temperature falls below the value that locked the display (or if a temperature

alarm is triggered)

(11) if P3 parameter is set at 0 or 2, the device will function as if d8 parameter were set at 0

(12) if when defrost is activated, the operating duration of the compressor is less than the time established with d15 parameter, the compressor will remain on for the amount of time

necessary to complete defrost, then the defrost shall be activated

(13) during defrost, dripping and evaporator fan standstill, the maximum temperature alarm is absent, provided that it was triggered after defrost activation.

(14) during activation of the door switch input, the maximum temperature alarm is absent, provided the alarm was signalled after the activation of the input

(15) F4 and F5 parameters have effect when the compressor is off

(16) F4 and F5 parameters have effect when the compressor is on

(17) if P3 parameter is set at 0, the device will function as if F0 parameter were set at 2

(18) F4 and F5 parameters have effect when the evaporator temperature is below the temperature established with F1 parameter

(19) F4 and F5 parameters have effect when the compressor is on and the temperature of the evaporator is below the temperature established with F1 parameter

(20) if the P4 parameter is set at 0, 2 or 3, the condenser fan shall work in parallel with the compressor

(21) the condenser fan is switched on provided that the compressor is switched on and is switched off when the condenser temperature falls below the value set with parameter F11

provided that the compressor is switched off

(22) the compressor is switched off 10 s after the activation of the input; if the input is activated during defrost or when the evaporator fan is deactivated, the activation will not have

any effect on the compressor
