ECM20/ECL60 Installation and Operation Manual
Table of Parameters
PAR. DESCRIPTION
SEt Temperature SEtpoint.
COMPRESSOR REGULATOR (folder with “CP” label)
diF 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 Higher SEt. Maximum possible setpoint value.
LSE Lower SEt. Minimum possible setpoint value.
OSP Offset Set Point. Temperature Value to be added to the Set-Point if reduced set is enabled (Economy function).
dOd digital (input) Open door. Digital input that allow you to switch off loads. Valid if H11 = ±4 (door microswitch).
n = does not switch off loads; y = switch off loads
COMPRESSOR PROTECTIVE DEVICE (folder with “CP” label)
Ont On time (compressor). Compressor activation time in the event of faulty probe. If Ont=0 the compressor is
always off, while Ont>0 the compressor is always on.
dOn delay (at) On compressor. Delay time in activating the compressor relay after switch-on of instrument.
dOF 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 delay between power-on. Delay between switch-ons; the indicated time must elapse between two successive
switch-ons of the compressor.
OdO (!) delay Output (from power) On. Delay time in activating the outputs after switch-on of the instrument or after
a power failure.
DEFROSTING REGULATOR (folder with “dEF” label)
dty 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 defrost interval time. Interval between the start of two successive defrosting operations.
dCt 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 defrost Offset Hour. Start-of-defrosting delay time from the call.
dEt defrost Endurance time. Defrosting time-out; determines duration of defrosting.
dSt defrost Stop temperature. Defrost stop temperature (defined by the evaporator probe).
dPO 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.
FANS REGULATOR (folder with “FAn” label)
FSt Fan Stop temperature. Fan lock temperature; if the value, read by the evaporator probe, is higher than the set
value, fans stop.
FAd Fan differential. Fan starting differential (see par. “FSt”).
Fdt Fan delay time. Delay time in activating fans after a defrost operation.
dt drainage time. Dripping time.
dFd defrost Fan disable. Allows to select the evaporator probes exclusion during defrost.
y = yes (fan disable); n = no.
FCO Fan Compressor OFF. Allows to select compressor fans lock OFF (switched off).
y = fans activated (with thermostat; based on the value read by the defrost probe, see parameter “FSt”);
n = fans off; dc = not used.
Fod 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.
