condenser probe offset
degree Celsius decimal point (for the sizes displayed during normal functioning)
1 = YES
temperature unit of measurement (2)
0 = °C

evaporator probe function
0 = no probe
1 = defrosting probe and probe for the temperature control system of the evaporator fan
2 = probe for the temperature control system of the evaporator fan
enabling of the condenser probe
1 = YES
display delay of the temperature variation detected by the probes
type of backlight
0 = off during the on status and active keys with low light intensity
1 = with low light intensity during the on state and active keys with high light intensity
2 = with high light intensity during the on state and all keys with high light intensity
MAIN REGULATOR
work set-point differential
minimum work set-point
maximum work set-point
block of work set-point modification (with the procedure indicated in paragraph 5.1)
1 = YES
temperature increases during Energy Saving function; see also i5 and i10
temperature decrease during Overcooling function; see also r6
duration of the Overcooling function; see also r5
minimum “cabinet temperature - work set-point” difference (on instrument switch-on) such to cause the exclusion of the consequent evaporator temperature value from those
used for the calculation of the relative average (for the activation of defrosting; only if d8 = 3); see also d17 (3)
COMPRESSOR PROTECTIONS
compressor switch-on delay from instrument switch-on (3)
minimum time between two consecutive switch-ons of the compressor; also pressure switch-on delay from the conclusion of the cabinet probe error (“Pr1”code) (4) (5)
minimum duration of compressor switch-off (4)
minimum duration of compressor switch-on
compressor switch-off duration during cabinet probe error (“Pr1” code); see also C5
compressor switch-on duration during cabinet probe error (“Pr1” code); see also C4
condenser temperature over which the overheated condenser alarm is activated (“COH” code) (6)
condenser temperature over which the compressor blocked alarm is activated (“CSd” code)
compressor blocked alarm delay (“CSd” code) (7)
number of compressor functioning hours above which a maintenance request is signalled
0 = no function
DEFROSTING
if d8 = 0, 1 or 2, defrosting interval (8)
0 = defrosting at intervals will never be activated
if d8 = 3, maximum defrosting interval
type of defrosting
0 = ELECTRIC - during defrosting the compressor will remain off and the defrosting output will be activated; the evaporator fan activity will depend on parameter F2
1 = WITH HOT GAS - during defrosting the compressor will be switched-on and the defrosting output will be activated; the evaporator fan activity will depend on parameter
F2
2 = DUE TO COMPRESSOR STOPPING - during defrosting the compressor will remain off and the defrosting output will be deactivated; the evaporator fan activity will depend
on parameter F2
temperature of defrosting end (only if P3 = 1); see also d3
if P3 = 0 or 2, duration of defrosting
if P3 = 1, maximum duration of defrosting; see also d2
0 = defrosting will never be activated
defrosting on instrument switch-on (only if d8 = 0, 1, 2 or 3) (3)
1 = YES
if d4 = 0, minimum time between switch-on of the instrument and the activation of defrosting; see also i5 (3)
if d4 = 1, defrosting activation delay from instrument switch-on; see also i5 (3)
temperature displayed during defrosting
0 = cabinet temperature
1 = if, on activation of defrosting, the cabinet temperature is below “work set-point + r0”, at maximum “work set-point + r0”; if, on activation of defrosting, the cabinet
temperature is above “work set-point + r0”, at maximum the temperature of the cabinet on activation of defrosting (9)
during dripping (during dripping the compressor will remain off and the defrosting output will remain deactivated. If d16 = 0, the evaporator fan activity will depend on
parameter F2; if d16 ≠ 0, the evaporator fan will remain off)
defrosting activation method
0 = AT INTERVALS - defrosting will be activated when the instrument has remained on completely for time d0
1 = AT INTERVALS - defrosting will be activated when the compressor has been left on completely for time d0
2 = AT INTERVALS - defrosting will be activated when the evaporator temperature as remained below temperature d9 completely for time d0 (10)
3 = ADAPTIVE - defrosting will be activated when one of the following conditions occurs; see also d0: (10)
- condition 1: the evaporator temperature will be below temperature d22 and the compressor will have remained on totally for time d18
- condition 2: the evaporator temperature will drop below temperature d19
temperature of the evaporator over which the defrosting interval count is suspended (only if d8 = 2)

minimum consecutive duration of the compressor, such to cause activation of defrosting
0 = defrosting will never be activated due to the effect of compressor switch-on
