Aoo Alarm override after Power-on: (0÷10h) Temperature alarm override duration after the instrument switching on, both
executed manually through the ON/OFF key or due to a power failure. The alarm remains inhibited for the time programmed.
Aod Alarm override after defrost: (0÷10h) Temperature alarm override time after the defrost end. The alarm remains inhibited
for the time programmed.
AoS Door opening alarm override: (0÷10h) Temperature alarm override duration after door opening. The alarm remains
deactivated during the time programmed.
AOP Alarm relay output staate: CL: activated = closed ; oP: activated = open.
DIGITAL INPUTS
Pnn Number of signals of the alarm module: (0÷15) In the interval time set at the "Pty" parameter, number of signals of the
alarm module that causes the alarm signalling and the disconnection of the compressor fan and defrost outputs. If the value set
at this parameter is equal to zero, the function is disconnected and no pressure switch alarm is given.
Pty Counting interval of the alarm module signals: (1÷99 min) Time interval during which the counting of the alarm
module signals is effected.
EFd Vacuum function delay: (1÷99min) Delay time between the compressor relay switching and the state change of the vacuum
digital input.
Ldd Light/door keys ON by device OFF: It determines if the light key and the door microswitch are on, even if the instrument
is off but supplied. n= the keys do not work; y= the keys work.
dSo Door microswitch switches off unit: Under the control of the door microswitch, it allows the unit switching off at the door
opening. It switches on again after the door closing. Any protection delay is respected anyway (e.g. delay at compressor
starting). n= it does not switch off the unit; y= it switches off the unit.
dSL Door light switching on: Under the control of the door microswitch, this parameter allows the light switching on (if it was
switched off) at door opening and its switching off at door closing. See also the "Idd" parameter.
n= by open door the light does not switch on; y= by open door the light switches on.
iP1 Polarity of the digital input 1: (door microswitch) CL= the digital input is activated when the contact is closed; oP= the
digital input is activated if the contact is open.
iP2 Polarity of the digital input 2: (alarm module) CL= the digital input is activated when the contact is closed; oP= the digital
input is activated if the contact is open.
iP3 Polarity of the digital input 3: (vacuum alarm) CL= the digital input is activated when the contact is closed; oP= the digital
input is activated if the contact is open.
iP4 Polarity of the digital input 4: (external control) CL= the digital input is activated when the contact is closed; oP= the digital
input is activated if the contact is open.
PROBES AND DISPLAYS
PbC Selection of probe type: Ptc= PTC probe; ntc= NTC probe.
C-F Celsius/Fahrenheit display: Through this parameter, it is possible to choose if the temperature value read by the probes has
to be expressed in Celsius or Fahrenheit grades. In case this parameter is changed from °C to °F or vice versa, the set values,
the differential etc. are not modified (e.g. if the programmed set is 10°C, by changing the display from °C to °F, the set will be 10°F).
OF1 Thermostat probe calibration: (-12÷12°C) Positive or negative temperature offset that is added to the value read by the
temperature control probe before it is displayed. The cold room temperature controller and the corresponding set points are linked
to the value displayed. The offset value is programmable with the same unit of measurement of the display.
P2P Evaporator probe presence: (Probe 2) n= probe not present (only time-controlled defrosts); y= probe present (defrost end
due to temperature).
OF2 Evaporator probe calibration: (-12÷12°C) Positive or negative temperature offset that is added to the value read by the
evaporator probe.
S2r Evaporator probe read: Display of the temperature read by the evaporator temperature probe.
P3P Presence of the third probe: n= probe not present; y= probe present.
P3F Function of the third probe: dF2= second evaporator. It reads the temperature of the second evaporator; Ao= it acts as digital output.
S3r Read of the third probe: Display of the temperature read by the third temperature probe.
OF3 Calibration of the third probe: (-12÷12°C) Positive or negative temperature offset that is added to the value read by the third probe.
