dFd Temperature displayed during
defrost
(rt = real temperature; it = temperature at defrost start; SEt = setpoint; dEF = dEF la-
bel)
dAd MAX display delay after de-
frost
(0 to 255 min)
Sets the maximum time between the end of defrost and the restarting of the real room
temperature display.
Fdt Drip time (0 to 120 min)
Time interval between reaching defrost termination temperature and the restoring of the
controller’s normal operation. This time allows the evaporator to eliminate water drops
that might have formed due to defrost.
dPo First defrost after start-up (y = immediately; n = after the IdF time)
dAF Defrost delay after continuous
cycle
(0 to 23.5 hr)
Time interval between the end of the fast freezing cycle and the following defrost related
to it.
FANS
FnC Fans operating mode C-n = runs with the compressor, OFF during defrost
O-n = continuous mode, OFF during defrost
C-y = runs with the compressor, ON during defrost
O-y = continuous mode, ON during defrost
Fnd Fans delay after defrost (0 to 255 min)
Interval between end of defrost and evaporator fans start
FCt Temperature differential avoid-
ing short cycles of fans
(0 to 59°C; FCt = 0 function disabled)
If the difference in temperature between the evaporator and the room probes is more
than the value of the FCt parameter, the fans are switched ON.
FSt Fans stop temperature (-50 to 50°C/ 122°F) Setting of temperature, detected by the evaporator probe, above
which fans are always OFF.
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. When Fon=0 and FoF≠0, the fans
are always OFF, with Fon=0 and FoF=0,
the fans 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. When Fon=0 and FoF≠0, the fans
are always OFF, when Fon=0 and FoF=0, the fans are always OFF.
FAP Probe selection for fan manage-
ment
nP = no probe
P1 = thermostat probe
P2 = evaporator probe
P3 = configurable probe
P4 = probe on Hot Key plug
AUXILIARY THERMOSTAT CONFIGURATION (terms. 1-4) - oA3 = AUS
ACH Kind of regulation for auxiliary
relay
Ht = heating
CL = cooling
SAA Setpoint for auxiliary relay (-100 to 150.0°C; -148 to 302°F)
Defines the room temperature setpoint to switch auxiliary relay.
SHy Differential for auxiliary output (0.1 to 25.5°C/ 1 to 255°F)
Intervention differential for auxiliary output setpoint.
When ACH = CL AUX Cut in is SAA + SHy; AUX Cut out is SAA
When ACH = Ht AUX Cut in is SAA - SHy; AUX Cut out is SAA
