• test the integrity of

the probe

• test the instrument-

• test the temperature

close to the probe (it

has to be between

the limits allowed by

the working range)

C5 and C6

any indication

the cabinet tempera-

the cabinet tempera-

ture is outside the limit

you have set with the

parameter A1A

• look at the param-

eter /0

• test the integrity of

the probe

• test the instrument-

probe connection

• test the temperature

close to the probe (it

has to be between

deactivate the input

(look at the parameters

i0, i1 and i6)

test the temperature

close to the probe

(look at the parameters

A0, A1b and A2b)

look at the parameters

A0, A1b, A2b, A8 and

test the temperature

close to the probe

(look at the parameters

A0, A1A and A2A)

• if the parameter dE

has value 2, the de-

frost interval count

will take place when

the only first evapo-

rator temperature

will be below the

temperature you

have set with the

parameter dF (if

each of the evapo-

rator probes are

wrong, the instru-

ment will work as if

the parameter had

value 0)

• the second evapo-

rator defrost will

end by time (param-

eter d3)

you will get the action

you have chosen with

the parameter i0

---

evaporator fan action during the normal operation (0 = it will be forced OFF, 1 = it will be

forced ON, 2 = it will work in accordance with the compressor, 3 = it will work in accordance

with F1 and F2, 4 = if the compressor is ON, it will work in accordance with F1 and F2, if the

compressor is OFF, it will be forced OFF)

LABEL MIN. MAX. U.M.

action given by the multifunction input activation (0 = inactive, 1 = once d5 has passed, the

defrost will be activated

, 2 = the cabinet light will be turned ON, 3 = the compressor will be

forced ON for A5 and the cabinet light will be turned ON, 4 = the compressor and the

evaporator fan will be forced OFF for A5 and the cabinet light will be turned ON,

5 = the evaporator fan will be forced OFF for A5 and the cabinet light will be turned ON,

6 = the working setpoint becomes r8, 7 = the working setpoint becomes r8 and the cabinet

light will be turned OFF); look at i7 as well

---

kind of contact of the multifunction input (it is important if i0 ≠ 0; 0 = NO, 1 = NC)

---

action given by the lock input/thermal protection activation (1 = the compressor will be forced

OFF, 2 = in accordance with i3, i4 and i5)

---

lock input/thermal protection alarms number such as to give the lock of the instrument (it is

important if i2 = 2; 0 = the lock of the instrument will never take place)

time without lock input/thermal protection alarms able to clear the lock input/thermal pro-

tection alarms counter (it is important if i2 = 2)

(15)

min

minimum delay between the lock input/thermal protection deactivation and the following

compressor activation (it is important if i2 = 2)

---

indication “Ain” flashing on the display during the multifunction input activation (it is impor-

tant if i0 ≠ 0)
