FnC
Fans operating mode
(C-n; o-n; C-Y; o-Y)
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 255min) Interval between end of defrost and evaporator
fans start.
Fct
Temperature differential to avoid fan
short cycles
(0 to 59°C; 0 to 90°F) (N.B.: if
Fct=0
function disabled) If the
difference of temperature between the evaporator and the room
probes is higher than
Fct
value, the fans will be switched ON.
FSt
Fans stop temperature
(-50 to 50°C; -58 to 122°F) Setting of temperature, detected by
evaporator probe, above which fans are always OFF.
Fon
Fan ON time
(0 to 15min) With
FnC=C_n
or
C_Y
, (fan activated in parallel
with compressor) it 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 15min)
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.
FAP
Probe selection for fan management
(nP; P1; P2; P3; P4)
nP
= no probe;
P1
=thermostat probe;
P2
=
evaporator probe;
P3
=configurable probe;
P4
= Probe on Hot
Key plug.
AUXILIARY THERMOSTAT CONFIGURATION (terms. 1-2) - oA2 = AUS
ACH
Kind of regulation for auxiliary relay
(Ht; CL)
Ht
= heating;
CL
= cooling
SAA
Set Point for auxiliary relay
(-50 to 110.0°C; -58 to 230°F) It defines the room temperature
setpoint to switch auxiliary relay.
SHY
Differential for auxiliary output
(0.1 to 25.5°C; 1 to 45°F) Intervention differential for auxiliary
output setpoint.
ACH=CL
, AUX Cut in is [
SAA+SHY
]; AUX Cut out is
SAA
.
ACH=Ht
, AUX Cut in is [
SAA–SHY]
; AUX Cut out is
SAA
.
ArP
Probe selection for auxiliary
(nP; P1; P2; P3; P4)
nP
= no probe, the auxiliary relay is
switched only by the digital input;
P1
= Probe 1 (Thermostat
probe);
P2
= Probe 2 (evaporator probe);
P3
= Probe 3 (display
probe);
P4
= Probe 4
Sdd
Auxiliary relay OFF during defrost
(n; Y)
n
= the auxiliary relay operates during defrost;
Y
= the
auxiliary relay is switched OFF during defrost
ALARMS
ALP
Probe selection for alarm
(nP; P1; P2; P3; P4)
nP
= no probe, the temperature alarms are
disabled;
P1
= Probe 1 (Thermostat probe);
P2
= Probe 2
(evaporator probe);
P3
= Probe 3 (display probe);
P4
= Fourth
probe
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.
