FoF
Fan OFF time
: (0 to 15 minutes)
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.
MODULATING OUTPUT - if present
trA
Kind of regulation with PWM output:
(UAL – rEG – AC) it selects the functioning for the PWM output.
UAL
= the output is at FSA value; rEG = the output is regulated with fan algorithm described in fan
section;
AC
= anti-sweat heaters control (require the XWEB5000 system).
SOA
Fixed value for analog output: (0 to 100%) value for the output if
trA=UAL.
SdP
Default value for Dewpoint:
(-55,0 to 50,0°C; -67 to 122°F) default value of dewpoint used when
there is no supervising system (XWEB5000). Used only when
trA = AC
.
ASr
Dew-point offset (trA=AC) / Differential for modulating fan regulation (trA = rEG):
(-25.5°C to 25.5°C) (-45°F to 45°F).
PbA
Differential for anti-sweat heaters:
(0.1°C to 25.5°C) (1°F to 45°F)
AMi
Minimum value for analog output:
(0 to AMA)
AMA
Maximum value for analog output:
(Ami to 100)
AMt
Anti-sweat heaters cycle period (trA=AC)/ Time with fan at maximum speed (trA=rEG)
:
(0 to 255 seconds) when the fan starts, during this time the fan is at maximum speed.
ALARMS
rAL
Probe for temperature alarm:
(nP - P1 - P2 - P3 - P4 - P5 – tEr) it selects the probe used to signal alarm
temperature.
ALC
Temperature alarm configuration: rE
= High and Low alarms related to Setpoint; Ab = High and low
alarms related to the absolute temperature.
ALU
High temperature alarm setting:
(ALC= rE, 0 to 50°C or 90°F / ALC= Ab, ALL to 150°C or 302°F) when
this temperature is reached and after the ALd delay time the
HA
alarm is enabled.
ALL
Low temperature alarm setting:
(ALC = rE, 0 to 50 °C or 90°F / ALC = Ab, - 55°C or - 67°F to ALU) when
this temperature is reached and after the
ALd
delay time, the
LA
alarm is enabled.
AHy
Differential for temperature alarm:
(0.1°C to 25.5°C / 1°F to 45°F) Intervention differential for
recovery of temperature alarm.
ALd
Temperature alarm delay:
(0 to 255 minutes) time interval between the detection of an alarm
condition and the corresponding alarm signaling.
rA2
Probe for second temperature alarm:
(nP - P1 - P2 - P3 - P4 - P5 – tEr) it selects the probe used to
signal alarm temperature.
A2U
Second high temperature alarm setting:
(A2L to 150°C or 302°F) when this temperature is reached
and after the
A2d
delay time the
HA2
alarm is signaled.
A2L
Second Low temperature alarm setting:
(- 55°C or - 67°F to A2U) when this temperature is reached
and after the
A2d
delay time, the
LA2
alarm is signaled.
A2H
Differential for second temperature alarm:
(0.1°C to 25.5°C / 1°F to 45°F) Intervention differential
for recovery of second temperature alarm.
Ad2
Second temperature alarm delay:
(0 to 255 minutes) time interval between the detection of second
temperature alarm condition and the corresponding alarm signaling.
dAO
Delay of temperature alarm at start-up:
(0 minutes to 23 hours, 50 minutes) time interval between
the detection of the temperature alarm condition after the instrument power on and the alarm
signaling.
EdA
Alarm delay at the end of defrost
: (0 to 255 minutes) Time interval between the detection of the
temperature alarm condition at the end of defrost and the alarm signaling.
dot
Temperature alarm exclusion after door open
: (0 to 255 minutes)
tbA
Disabling alarm relay by pressing a key:
(N; Y)
