Parameter DESCRIPTION
Regulators blocked by external alarm.
rLO = 0 no resources blocked.
rLO
rLO = 1 compressor and defrost blocked.
rLO = 2 compressor, defrost and fans blocked.
LIGHT AND DIGITAL INPUTS
dSd Enable light relay from door switch n = light not turned on when door opened; y= light turns on when door opened (if it was off).
Light relay (room light) deactivation (switch-off) delay. The light relay remains on fordLtminutes when the door is closed if parameter
dLt
dSd is set to switch on the light.
Light key always disables the light relay. Enables switching off with cold room light switch even if the delay after closing the door set
OFL
by dLt is enabled.
Door switch switches off loads. On digital input command, programmed as door switch, this allows all loads to be switched off when
dOd
the door is opened and restarted when the door is closed (observing any currently running timings).
dAd Delay activating Digital Inputs DI1 and DI2.
di3 Delay activating Digital inputs DI3 and DI4.
dOA Action forced by digital input.
PEA Enable forced action from door switch or external alarm.
dCO Delay activating compressor after request
dFO Delay activating fans after request
PRESSURE SWITCH (folder PrE)
PEn Number of errors allowed per maximum/minimum pressure switch input. 0 = disabled
PEI Minimum/maximum pressure switch error count interval.
COMMUNICATION
(folder Add)
dEA (!) dEvice Address. Device address: indicates the device address to the management protocol.
FAA (!) FAmily Address. Family address: indicates the device family to the management protocol.
DISPLAY (folder diS)
LOCk. Block Setpoint modification See corresponding paragraph. You can still access the parameter programming menu and edit the
LOC
parameters, including this parameter, in order to allow keyboard unlocking. n = no; y = yes.
PA1 PAssword 1. When enabled (PA1
PA2 PAssword 2. When enabled (PA2
ndt number display type. Display with decimal point. n = no (integers only); y = yes (displayed with decimal point).
CAlibration 1. Calibration 1.
CA1
Positive or negative temperature value added to the value read by Pb1, according to the setting of parameter "CAI".
CAlibration 2. Calibration 2.
CA2
Positive or negative temperature value added to the value read byPb2, according to the setting of parameter "CAI".
CAlibration Intervention. Activation of offset for display, temperature control or both:
0 = only the temperature shown is modified.
CAI
1 = sum with only the temperature used by the regulators, not for the display, which remains unchanged.
2 = sum with the displayed temperature, which is also used by the regulators.
defrost display Lock. Display mode during defrost.
0 = displays the temperature read by probe Pb1.
ddL 1 = locks the reading at the temperature value read by thermostat probe when defrosting starts and until the
next time the Setpoint value is reached.
2 = displays the label "deF" during defrosting and until the next time the Setpoint value is reached (or until Ldd has elapsed).
Lock defrost disable. Timeout value to unlock the display (label dEF) if the time to reach setpoint is too long during defrost, or if LAN
Ldd
communication between master and slave is interrupted (E7 error).
display readout. Selection of °C or °F to display the temperature read by the probe. 0 = °C, 1 = °F.
dro
N.B.: switching between °C and °F or vice versa DOES NOT modify the setpoint, differential, etc (e.g. set=10°C becomes 10°F).
Selects type of value to display.
ddd
0 = Setpoint; 1 = cold room probe Pb1; 2 = evaporator probe Pb2; 3 = display probe Pb3.
CONFIGURATION (folder CnF)
Determines if the AUX/light door switch key/input are active when the device is OFF (but power on).
H06
n = key and DI not active when OFF; y = key and DI active when OFF.
Configuration of digital input/polarity (D.I.4).
0 = disabled; ±1 = defrost; ±2 = reduced setpoint; ±3 = AUX; ±4 = door switch; ±5 = external alarm; ± 6 = not used.
±7 = stand-by (ON-OFF); ±8 = not used; ±9 = minimum pressure switch; ±10 = maximum pressure switch; ± 11 = general
H14 pressure switch.
± 12 = not used; ±13 = force evaporator fans; ±14 = activate light relay; ±15 = not used; ±16 = not used.
N.B.: - The "+" sign indicates that the input is active when the contact is closed.
- The "-" sign indicates that the input is active when the contact is open.
H41 Regulation probe (Pb1) present. n= not present; y= present.
H42 Evaporator probe (Pb2) present. n= not present; y= present.
H60 Select parameter vector.
reL Firmware version Device software release: read-only parameter.
tAb Parameters table... Reserved: read-only parameter.
COPY CARD (folder Fpr)
UL Upload Transfer of programming parameters from instrument to Copy Card
dL Download Transfer of programming parameters from Copy Card to instrument
Formatting. Deletes data on Copy Card.
Fr
IMPORTANT: if parameter "Fr" is used, the data entered will be permanently lost. This operation cannot be reversed.
NOTE: If one or more of the parameters marked with (!) are modified, the controller MUST be switched off then back on again to
make sure it continues to function properly.

0), this is the access key to the User parameters (User).
≠
0, this is the access key to the installer parameters (Installer).
≠
- N.B.:the instrument must be switched off then back on again each time parameters are modified to prevent malfunction of
the configuration and/or timer operations underway.
