Auxiliary Output Parameters List • 15
FHy
Differential to restart fan: (1°F to 45°F) (0.1°C to 25.5°C) when stopped, fan restarts when fan probe reaches
FSt-FHy temperature.
Fod Fan activation time after defrost: (0 to 255 min.) it forces fan activation for indicated time.
Fon
Fan ON time: (0 to 15 min) with Fnc = C_n or C_y, (fan activated in parallel with compressor). Sets the
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.
FoF
Fan OFF time: (0 to 15 min) with Fnc = C_n or C_y, (fan activated in parallel with compressor). Sets the
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.
MODULATING OUTPUT (AnOUT) If Present
trA
Kind of regulation with PWM output: (UAL - rEG - AC) it selects the functioning for the PWM output if
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.
SdP
Default value for Dew point: (-67 to 122°F; -55.0 to 50.0°C) default value of dew point 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): (-45°F to 45°F)
(-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)
AMt
Anti-sweat heaters cycle period (trA=AC)/ Time with fan at maximum speed (trA=rEG): (0 to 255 s) 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) 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 90°F or 50°C / ALC= Ab, ALL to 302°F or 150°C) 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 90°F or 50 °C / ALC = Ab, - 67°F or - 55°C to ALU) when
this temperature is reached and after the ALd delay time, the LA alarm is enabled.
AHy
Differential for temperature alarm: (1°F to 45°F / 0.1°C to 25.5°C) Intervention differential for recovery of
temperature alarm.
ALd
Temperature alarm delay: (0 to 255 min) The time interval between the detection of an alarm condition and
the corresponding alarm signaling.
dLU
High temperature alarm (defrost probe): (ALC= rE, 0 to 90°F or 50°C / ALC= Ab, ALL to 302°F or 150°C)
When this temperature is reached and after the ddA delay time, the HAd alarm is enabled.
dLL
Low temperature alarm (defrost probe): (ALC = rE, 0 to 90°F or 50 °C / ALC = Ab, - 67°F or - 55°C to ALU)
when this temperature is reached and after the ALd delay time, the LAd alarm is enabled.
