Parameter DESCRIPTION
DEFROST (folder dEF)
defrost type. Type of defrost.
0 = electric defrost - compressor OFF during defrost cycle.
dty
1 = cycle inversion defrost (hot gas) - compressor ON during defrost cycle.
2= "Free": defrosting independently of compressor
defrost interval time. Interval between the start of two consecutive defrost cycles.
dit
0 = function disabled (defrosting NEVER performed).
defrost Counting type. Selects the count mode for the defrost interval.
0 = compressor hours of operation (DIGIFROST® method); Defrost active ONLY when the compressor is on.
N.B.: compressor operation time is counted separately from the evaporator probe (count active also when
dCt evaporator probe missing or faulty).
1 = appliance running hours = the defrost count is always active when the machine is on and starts at each power-on.
2 = compressor stop Every time the compressor stops, a defrost cycle is performed according to parameter dtY;
3 = not USED
dCt
defrost relay
0 = compressor running
ON when dit is reached
hours
OFF when Pb2=dSt or due to time (dEt)
1 = real time
ON when dit is reached
OFF when Pb2=dSt or due to time (dEt)
2 = compressor stop
ON when compressor OFF
OFF when Pb2=dSt or due to time (dEt)
3 = not used
dOH defrost Offset Hour. Defroststart delay time after request.
dEt defrost Endurance time. Defrost time-out; determines the maximum defrost duration.
dSt defrost Stop temperature. Defrost end temperature (determined by the evaporator probe).
defrost (at) Power On. Determines whether the instrument must enter defrost mode (if the temperature measured by the evaporator
dPO
allows this operation). n = no, does not start defrosting at start-up; y = yest, starts defrost at start-up.
time compressor for defrost. Minimum compressor ON or OFF time before defrost.
- if tcd > 0 (positive value) the compressor stays ON for "tcd" minutes.
tcd
- if tcd < 0 (negative value) the compressor stays OFF for "tcd" minutes.
- if tcd = 0 the parameter is ignored.
Compressor off (before) defrost. Compressor OFF time near a defrost cycle. If a defrost is programmed during the period of time set in
Code
this parameter, the compressor is not turned on If Code = 0 the function is excluded.
FAN REGULATOR
(folder FAn)
Fan Stop temperature. Block fan temperature; if the evaporator probe reads a higher value than the set value, the fans are stopped.
FSt The value is either positive or negative and, depending on parameter FPt, can be either the absolute temperature or the temperature
relative to the Setpoint.
FAd FAn differential. Fan activation intervention differential (see parameters "FSt" and "Fot").
Fdt Fan delay time. Fan activation delay after a defrost cycle.
dt drainage time. Dripping time.
dFd defrost Fan disable. Allows exclusion of the evaporator fans to be selected or not selected during defrosting. y = yes; n = no.
Fan Compressor OFF. Selects or deselects fan deactivation at compressor OFF.
FCO n = fans off; y = fans on (with thermostat; depending on the value read by the defrosting probe, see parameter "FSt")
dc = duty cycle (via parameters "Fon" and "FoF" ).
Fan open door open. Allows fan block to be selected when the door is open and fan restart when the door is shut (if they were
Fod
running). n= fans blocked; y=fans unaltered
FdC Fan delay Compressor off. Fans switch-off delay after compressor stop; in minutes. 0= function excluded.
Fan on (in duty cycle). Fan ON time in duty cycle
Fon
Fans used in duty cycle mode; valid when FCO = dc and H42=y (evaporator probe present)
Fan oFF (in duty cycle). Fan OFF time in duty cycle
FoF
Fans used in duty cycle mode; valid when FCO = dc and H42=y (evaporator probe present)
ALARMS (folder AL)
Alarm type. Parameters "HAL" and "LAL"" intended as the absolute temperature value or differential in relation to the setpoint.
0 = absolute value; 1 = relative value.
Att
N.B.: In case of relative values (para. Att=1) parameter HAL should be set to positive values, whilst parameter LAL
should have only negativ values (-LAL).
AFd Alarm diFferential. Alarm differential.
Higher ALarm. Maximum temperature alarm. Temperature value (intended either as distance from set point or as an absolute value
HAL (!)
based on Att) which, if exceeded in an upward direction, triggers the activation of the alarm signal. See Max/Min Alarms Table.
Lower ALarm. Minimum temperature alarm. Temperature value (intended as distance from the Setpoint or as an absolute value
LAL (!)
based on Att which, when exceeded downwards, triggers the activation of the alarm signal. See Max/Min Alarms Table.
Power-on Alarm Override. Alarm override time after device is switched on following a power failure.
PAO (!)
This parameter refers to high/low temperature alarms only.
dAO defrost Alarm Override. Temperature alarm exclusion time after defrost.
OAO Alarm signal delay (low and high temperature) after the deactivation of the digital input (port closed).
tdO time out door Open. Delay in door open alarm activation.
temperature Alarm Override. Time delay for temperature alarm indication.
tAO
This parameter refers to high/low temperature alarms only.
dAt defrost Alarm time. Alarm signalling end of defrost due to timeout (n = alarm not activated; y = alarm activated).
AOP Alarm Output Polarity. Polarity of the alarm output (0 = alarm active and output disabled; 1 = alarm active and output enabled).
tP Enable all keys to acknowledge an alarm.
