7.1.5 EVAPORATOR FANS - FAn
FAP
Probe selection for evaporator fan:
(nP; P1; P2; P3; P4)
nP
=no probe;
Px
=
probe “x”. Note:
P4
=Probe on Hot Key plug.
FSt
Evaporator fan stop temperature:
(-55 to 50°C; -67 to 122°F) setting of temperature, detected
by evaporator probe. Above this temperature value fans are always OFF.
NOTE: it works only
for the evaporator fan, NOT for the condenser fan.
HYF
Evaporator fan regulator differential:
(0.1 to 25.0°C; 1 to 45°F)
oF2
Evaporator fan offset in energy saving:
(-12 to 12°C; -21.6 to 21.6°F) offset to add during
energy saving (
FSt+oF2
)
FnC
Evaporator fan operating mode:
(Cn; on; CY; oY)
•
Cn
= runs with the compressor, duty-cycle when compressor is OFF (see
FoF
,
Fon
,
FF1
and
Fo1
parameters) and OFF during defrost
•
on
= continuous mode, OFF during defrost
•
CY
= runs with the compressor, duty-cycle when compressor is OFF (see
FoF
,
Fon
,
FF1
and
Fo1
parameters) and ON during defrost
•
oY
= continuous mode, ON during defrost
Fnd
Evaporator fan delay after defrost cycle:
(0 to 255 min) delay before fan activation after any
defrosts.
FCt
Differential temperature for cyclic activation of evaporator fans (0=disabled)
: (0 to 50°C)
FSU
Evaporator fan operating mode:
(Std; Fon; FoF)
Std
= standard mode, evaporator fan uses par
FnC
;
Fon
= evaporator Fan always on;
FoF
= evaporator fan always off.
Fon
Evaporator fan ON time in normal mode (with compressor OFF):
(0 to 255 min) used when
energy saving status is not active.
FoF
Evaporator fan OFF time in normal mode (with compressor OFF):
(0 to 255 min) used when
energy saving status is not active.
Ft
Evaporator fan controlled during defrost:
(n; Y) when activated, the evaporator fan will be
regulated during any defrost.
Fo1
Evaporator fan ON time in energy saving mode (with compressor OFF):
(0 to 255 min) used
when energy saving status is active.
FF1
Evaporator fan OFF time in energy saving mode (with compressor OFF):
(0 to 255 min) used
when energy saving status is active.
7.1.6 AUXILIARY REGULATOR - AUS
ACH
Type of control for auxiliary regulator:
(Ht; CL)
Ht
= heating;
CL
= cooling.
SAA
Set Point for auxiliary regulator:
(-55.0 to 150.0°C; -67 to 302°F) it defines the room
temperature set point to switch auxiliary relay.
SHY
Auxiliary regulator differential:
(0.1 to 25.5°C; 1 to 45°F) differential for auxiliary output set
point.
-
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 regulator:
(nP; P1; P2; P3; P4)
nP
= no probe, the auxiliary relay
is switched only by the digital input;
Px
=
probe “x”. Note:
P4
=Probe on Hot Key plug.
Sdd
Auxiliary regulator disabled during any defrost cycle:
(n; Y)
n
= the auxiliary relay operates
during defrost.
Y
= the auxiliary relay is switched off during defrost.
btA
Base time for parameters Ato and AtF:
(SEC; Min)
SEC
= base time is in second; Min = base
time is in minutes.
Ato
Interval of time with auxiliary output ON:
0 to 255 (base time defined in par.
btA
)
AtF
Interval of time with auxiliary output OFF:
0 to 255 (base time defined in par.
btA
)
7.1.7 TEMPERATURE ALARM - ALr
ALP
Probe selection for temperature alarms:
(nP; P1; P2; P3; P4)
nP
=no probe;
Px
=
probe “x”.
Note:
P4
=Probe on Hot Key plug.
ALC
Temperature alarms configuration:
(Ab, rE)
Ab
= absolute;
rE
= relative.
ALL
Low temperature alarm:
when this temperature is reached, the alarm is enabled after the
Ad
delay time.
•
If
ALC=Ab
→
-55.0°C to ALU or -67°F to ALU.
•
If
ALC=rE
→
0.0 to 50.0°C or 0 to 90°F.
