The ON/OFF Function
Parameters • 11
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 setpoint. Temperature alarm is enabled
when the temperature exceeds the
SEt
+
ALU
or
SEt
-
ALL
values.
ALU
MAXIMUM temperature alarm
(
ALL
to 110°C;
ALL
to 230°F)
When this temperature is reached, the alarm is enabled
after the
ALd
delay time.
ALL
Minimum temperature alarm
(-100°C to
ALU
; -148 to
ALU
)
When this temperature is reached, the alarm is enabled
after the
ALd
delay time.
AFH
Differential for temperature alarm recovery
(0.1 to 25.5°C; 1 to 45°F)
Intervention differential for recovery of temperature
alarm.
ALd
Temperature alarm delay
(0 to 255 min)
Time interval between the detection of an alarm condi-
tion and alarm signaling.
dAo
Exclusion of temperature alarm at start-up
(from 0.0 min to 23.5 hr)
Time interval between the detection of the temperature
alarm condition after controller power ON and alarm sig-
naling.
CONDENSER TEMPERATURE ALARM
AP2
Probe selection for temperature alarm of con-
denser
nP
= no probe
P1
= thermostat probe
P2
=
evaporator probe
P3
= configurable probe
P4
= probe on Hot Key plug
AL2
Low temperature alarm of condenser
(-100 to 150°C; -148 to 302°F)
When this temperature is reached the
LA2
alarm is sig-
naled, possibly after the
Ad2
delay.
AU2
High temperature alarm of condenser
(-100 to 150°C; -148 to 302°F)
When this temperature is reached the
HA2
alarm is sig-
naled, possibly after the
Ad2
delay.
AH2
Differential for temperature condenser alarm
recovery
(0.1 to 25.5°C; 1 to 45°F)
Ad2
Condenser temperature alarm delay
(0 to 255 min)
Time interval between the detection of the condenser
alarm condition and alarm signaling.
dA2
Condenser temperature alarm exclusion at
start up
(from 0.0 min to 23.5 hr, res. 10 min)
bLL
Compressor OFF with low temperature alarm
of condenser
n
=
no:
compressor keeps on working
Y
=
yes:
compressor is switched OFF until the alarm is
present, in any case regulation restarts after
Ac
time at
minimum
AC2
Compressor OFF with high temperature alarm
of condenser
n
=
no:
compressor keeps on working
Y
=
yes:
compressor is switched OFF till the alarm is
present, in any case regulation restarts after
Ac
time at
minimum
