FoF Fan OFF time: (0÷15 min) with Fnc = C_n or C_y, (fan activated
in parallel with compressor). it sets the evaporator fan off cycling
time when the compressor is off. With Fon =0 and FoF ≠ 0 the
fan are always off, with Fon=0 and FoF =0 the fan are always
off.
ALARMS
ALC Temperature alarms configuration: (Ab; rE) Ab= absolute
temperature: alarm temperature is given by the ALL or ALU
values. rE = temperature alarms are referred to the set point.
Temperature alarm is enabled when the temperature exceeds
the "SET+ALU" or "SET-ALL" values.
ALU MAXIMUM temperature alarm: (SET÷110°C) when this
temperature is reached the alarm is enabled, after the "ALd"
delay time.
ALL Minimum temperature alarm: (-50.0÷SET°C) when this
temperature is reached the alarm is enabled, after the "ALd"
delay time.
ALd Temperature alarm delay: (0÷255 min) time interval between
the detection of an alarm condition and alarm signalling.
dAO Exclusion of temperature alarm at startup: (from 0.0 min to
24h) time interval between the detection of the temperature
alarm condition after instrument power on and alarm signalling.
RELAY CONFIGURATION

ALr= alarm; LiG= light; AUS= do not select it; OnF= on /off;
db= neutral zone; CP2= do not select it; dF2= do not select it.
oA2 Relay 11-12 configuration: dEF= defrost;
ALr= alarm; LiG= light; AUS= do not select it; OnF= on /off;
db= neutral zone; CP2= do not select it; dF2 = do not select
it.

After 10 seconds the instrument will restart working with the new
parameters.
5.
Remove the "Hot Key".
NOTE the message "Err" is displayed for failed programming. In this
case turn the unit off and then on if you want to restart the download
again or remove the "Hot key" to abort the operation.
10. ALARM RECOVERY
(Ref. Tab.4) Probe alarms "P1", "P2", start some seconds after the
fault in the related probe; they automatically stop some seconds after
the probe restarts normal operation.
Temperature alarms "HA", "LA" automatically stop as soon as the
temperature returns to normal values.
