Param. DESCRIPTION RANGE M.U. AP1 AP2 AP3
CAi
CAlibration Intervention. Activation of offset for display, temperature control or both.
0 = only temperature shown is modified;
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.
0/1/2 num 2 2 2
ddL
Display mode during defrost.
0 = displays the temperature read by probe Pb1;
1 = locks the reading at the temperature value read by probe Pb1 when defrosting starts and until the
next time the SEt is reached;
2 = displays the label deF during defrosting and until the next time the SEt* is reached (or until Ldd has elapsed).
(* See parameter dCS and "Deep Cooling Cycle" paragraph)

Ldd Timeout value for display unlock - label dEF 0 ... 255 min 30 30 60
dro
Selection of °C or °F to display the probe value. 0 = °C, 1 = °F. NOTE: switching from °C to °F or
vice versa DOES NOT modify the setpoint, differential, etc. (e.g. set=10°C becomes 10°F).
0/1 num 0 0 0
ddd
Selects type of value to display.
0 = setpoint; 1 = probe Pb1; 2 = probe Pb2; 3 = probe Pb3.

FSE Display filter sensibility. 0 = disabled. 0 ... 7 num 6
Parameters
not present
in vectors
FdS Filter de-activation threshold. -55.0...230 °C/°F 0.0
Ftt Time elapsed above threshold. 0 ... 250 min 15
FHt Sampling time. 1 ... 250 secs 8
CONFIGURATION (folder CnF) - NOTE: the instrument must be switched off and then on again each time the configuration of parameters
in folder CnF is modified in order to prevent malfunction of the configuration and/or ongoing timings.
H08
Function when in standby mode.
0 = display off; the regulators are active and the device reactivates the display to signal any alarms;
1 = display off; regulators and alarms blocked;
2 = display shows OFF label; regulators and alarms blocked.
0/1/2 num 2 2 2
H11
Configuration of digital input 1/polarity (DI1).
0 = disabled; ± 1 = defrost; ± 2 = reduced set; ± 3 = AUX; ± 4 = door switch;
± 5 = external alarm; ± 6 = stand-by (ON-OFF); ± 7 = pressure switch; ± 8 = deep cooling;
± 9 = energy saving; ± 10 = door switch + energy saving.
NOTE: - 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

10 = evaporator 2 defrost; 11 = compressor 2.

H42 Presence of Evaporator probe (Pb2). n (0) = not present; y (1) = present. n/y flag y y y
H43 Probe 3 (Pb3) present. n (0) = not present; y (1) = present; 2EP (2) = evaporator 2 defrost. n/y/2EP flag 2EP 2EP n
H45
Start defrost mode for applications with double evaporator.
0 = evaporator 1 only;
1 = if at least one of the evaporators is below its defrost end temperature
Pb2 value < dS1 (evaporator 1) or Pb3 value < dS2 (evaporator 2);
2 = if both evaporators are below their respective defrost end temperature
Pb2 value < dS1 (evaporator 1) and Pb3 value < dS2 (evaporator 2).
