Level DESCRIPTION
PAR
SEt Temperature SEtpoint.
COMPRESSOR
diF 1&2 diFferential. Relay compressor tripping differential. The compressor stops on reaching the Setpoint value (as indicated by the
adjustment probe), and restarts at temperature value equal to the Setpoint plus the value of the differential. Note: the value 0
cannot be assumed
HSE 1&2 Higher SEt. Maximum possible setpoint value.
LSE 1&2 Lower SEt. Minimum possible setpoint value.
OSP 2 Offset Set Point. Temperature Value to be added to the Set-Point if reduced set is enabled (Economy function).
dOd 2 digital (input) Open door. Digital input that allow you to switch off loads.
Valid if H11 = ±4 (door switch). n = does not switch off loads; y = switch off loads.
dAd 2 digital (input) Activation delay. Delay time in activating the digital input.
Ont 2 ON time (compressor). Compressor activation time in the event of faulty probe. If OFt=1 and Ont=0, the compressor is always
off, while if OFt=1 and Ont>0 it operated in duty cycle mode.
OFt 2 OFF time (compressor). Compressor deactivation time if probe is faulty. If Ont=1 and OFt=0, the compressor is always on, while if
Ont=1 and OFt>0 it operated in duty cycle mode.
dOn 2 delay (at) On compressor. Delay time in activating the compressor relay after switch-on of instrument.
dOF 2 delay (after power) OFF. Delay after switch off; the indicated time must elapse between switch-off of the compressor relay and
the successive switch-on.
dbi 2 delay between power-on. Delay between switch-ons; the indicated time must elapse between two successive switch-ons of the
compressor.
OdO (!) 2 delay Output (from power) On. Delay time in activating the outputs after switch-on of the instrument or after a power failure.
DEFROST
dty 1&2 defrost type. Type of defrosting.
0 = electric defrost - compressor off (OFF) during defrosting;
1 = reverse cycle defrost (hot gas); compressor on (ON) during defrosting;
2 = Free defrost; defrosting independently of compressor.
dit 1&2 defrost interval time. Interval between the start of two successive defrosting operations.
dCt 2 defrost Counting type. Selection of count mode for the defrosting interval.
0 = compressor operating hours (DIGIFROST® method);
Defrosting active only if compressor is on;
1 = Real Time - equipment operating hours; defrost counting is always active when the machine is on and start everytime
the instrument switch on;
2 = compressor stop. Each time the compressor stops a defrosting cycle is performed according to parameter dtY.
dOH 2 defrost Offset Hour. Start-of-defrosting delay time from the call.
dEt 1&2 defrost Endurance time. Defrosting time-out; determines duration of defrosting.
dSt 1&2 defrost Stop temperature. Defrost stop temperature (defined by the evaporator probe).
dPO 2 defrost (at) Power On. Determines if at the start-up the instrument must enter defrosting (if the temperature measured by
the evaporator allows this operation). y = yes; n = no.
EVAPORATOR FAN
FPt 2 Fan Parameter type. Characterizes the 'FSt' parameter that can be expressed or as an absolute temperature value or as a value
related to Setpoint. 0 = absolute 1 = relative.
FSt 1&2 Fan Stop temperature. Fan lock temperature; if the value, read by the evaporator probe, is higher than the set value, fans stop.
FAd 2 FAn differential. Fan starting differential (see par. 'FSt').
Fdt 1&2 Fan delay time. Delay time in activating fans after a defrost operation.
dt 1&2 drainage time. Dripping time.
defrost Fan disable. Allows to select the evaporator probes exclusion during defrost.
dFd 1&2
y = yes (fan disable); n = no.
Fan Compressor OFF. Allows to select compressor fans lock OFF (switched off).
FCO 2
y = fans activated (with thermostat; based on the value read by the defrost probe, see
parameter "FSt"); n = fans off; dc = not used.
Fod 2 Fan open door. Fans active when the door is open.
Allows you to select the option of stopping the fans when the door is open, and re-starting the fans when door is closed (if
they were active). n = fans stop; y = fans unchanged.
ALARMS
Att 2 Allow you to select if the parameters HAL and LAL will have absolute (Att=0) or relative (Att=1)
AFd 2 Alarm Fan differential. Alarm differential.
HAL 1&2 Higher ALarm. Maximum temperature alarm. Temperature value (in relative value) which if
upward direction triggers the activation of the alarm signal.
LAL 1&2 Lower ALarm. Minimum temperature alarm. Temperature value (in relative value), which if
downward direction, triggers the activation of the alarm signal.
PAO 2 Power-on Alarm Override. Alarm exclusion time after instrument switch on, after a power failure.
dAO 2 defrost Alarm Override. Temperature alarm exclusion time after defrost.
