ALARM PARAMETERS
A0 Alarm and fan differential C 0.1 +20 °C/°F 0.2
AL Low temperature alarm (indicates the max. allowed deviation from
the set- point). If = 0 disables the low temperature alarm
F 0 +199 °C/°F 0
AH High temperature alarm (indicates the max. allowed deviation from
the set-point). If = 0 disables the high temperature alarm
F 0 +199 °C/°F 0
Ad Temperature alarm delay C 0 199 min 120
A4 Digital input n.1 configuration C 0 7 - 0
A5 Digital input n.2 configuration C 0 7 - 0
A6 Cut-out of compressor by external alarm: 0=OFF, 100=ON Enabled
if either A4 or A5= 1 or 2, see Duty setting and digital input
C 0 100 min 0
A7 Delay in registration of the input <<delayed alarm>> (A4 or A5 = 2) C 0 199 min 0
F
FAN PARAMETERS
F0 Management of fans: 0 = always activated fans except on specific
phases (see parameters F2, F3, and Fd)
1= fans controlled by a thermostat according to the difference
between ambient temp. and evap. temp.,
2= fans controlled by a thermostat according to the evaporator
temperature
C 0 2 flag 0
F1 Fans activation temperature: if F0=1 it is the minimum difference
between ambient temp. and evap. temp. (t. evap. < t.amb.)
if F0=2, the fan is ON if Evap.temp<Setpoint + F1 - A0
the fan is OFF if Evap.temp. > Setpoint + F1
F 0 +20 °C/°F 5
F2 Stop fans when compr. is Off (0=no, 1=yes). Active if F0=0 C 0 1 flag 1
F3 Stop fans during defrost (0=no,1=yes).
This parameter is active for any value of F0
C 0 1 flag 1
Fd Stop after dripping. Active for any value of F0 F 0 15 min 1
H
OTHER SETTING
H0 Address within network C 0 15 - 0
H1 Selection of relay 4 functioning: 0= auxiliary output, 1=normally de-
energised alarm, 2= normally energised alarm
C 0 2 flag 0
H2 0= buttons inhibited; 2= buttons & IR inhibited; 3=IR inhibited C 0 3 flag 1
H3 Code to enable remote programming C 00 199 - 00
