Differential to restart fan: (1°F to 45°F) (0.1°C to 25.5°C) when stopped, fan restarts when fan probe reaches
FHy
FSt-FHy temperature.
Fod
Fan activation time after defrost: (0 to 255 min.) it forces fan activation for indicated time.
Fan ON time: (0 to 15 min) with Fnc = C_n or C_y, (fan activated in parallel with compressor). Sets the
Fon
evaporator fan ON 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.
Fan OFF time: (0 to 15 min) with Fnc = C_n or C_y, (fan activated in parallel with compressor). Sets the
FoF
evaporator fan off cycling time when the compressor is off. With Fon =0 and FoF =0 the fans are always off,
with Fon=0 and FoF =0 the fans are always off.
Kind of regulation with PWM output: (UAL - rEG - AC) it selects the functioning for the PWM output if
trA
CoM is not equal to OA7. 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.
Default value for Dew point: (-67 to 122°F; -55.0 to 50.0°C) default value of dew point used when there is
SdP
no supervising system (XWEB5000). Used only when trA=AC.
Dew-point offset (trA=AC) / Differential for modulating fan regulation (trA=rEG): (-45°F to 45°F)
ASr
(-25.5°C to 25.5°C).
PbA
Differential for anti-sweat heaters: (1°F to 45°F) (0.1°C to 25.5°C)
AMi
Minimum value for analog output: (0 to AMA)
AMA
Maximum value for analog output: (Ami to 100)
Anti-sweat heaters cycle period (trA=AC)/ Time with fan at maximum speed (trA=rEG): (0 to 255 s) when
AMt
the fan starts, during this time the fan is at maximum speed.
Probe for temperature alarm: (nP - P1 - P2 - P3 - P4 - P5 - tEr) Selects the probe used to signal alarm
rAL
temperature.
Temperature alarm configuration: rE = High and Low alarms related to Setpoint; Ab = High and low alarms
ALC
related to the absolute temperature.
High temperature alarm setting: (ALC= rE, 0 to 90°F or 50°C / ALC= Ab, ALL to 302°F or 150°C) when
ALU
this temperature is reached and after the ALd delay time the HA alarm is enabled.
Low temperature alarm setting: (ALC = rE, 0 to 90°F or 50 °C / ALC = Ab, - 67°F or - 55°C to ALU) when
ALL
this temperature is reached and after the ALd delay time, the LA alarm is enabled.
Differential for temperature alarm: (1°F to 45°F / 0.1°C to 25.5°C) Intervention differential for recovery of
AHy
temperature alarm.
Temperature alarm delay: (0 to 255 min) The time interval between the detection of an alarm condition and
ALd
the corresponding alarm signaling.
High temperature alarm (defrost probe): (ALC= rE, 0 to 90°F or 50°C / ALC= Ab, ALL to 302°F or 150°C)
dLU
When this temperature is reached and after the ddA delay time, the HAd alarm is enabled.
Low temperature alarm (defrost probe): (ALC = rE, 0 to 90°F or 50 °C / ALC = Ab, - 67°F or - 55°C to ALU)
dLL
when this temperature is reached and after the ALd delay time, the LAd alarm is enabled.
