Alarm relay
With
oAx=ALr
the AUX relay operates as alarm relay. It is activated every time an alarm happens. Its
status depends on the
tbA
parameter: if
tbA=Y
, the relay is silenced by pressing any key.
If
tbA=n
, the alarm relay stay on until the alarm condition recovers.
8.1.6
Activation during energy saving cycles
With
oAx=HES,
the AUX relay is energised when the energy saving cycle is activated.

PARAMETERS
REGULATION
Set
Regulation Set Point:
LS to US
LS
Minimum SET POINT:
(-55.0°C to SET; -67°F to SET) sets the minimum value for the set
point.
US
Maximum SET POINT:
(SET to 150.0°C; SET to 302°F) set the maximum value for set point.
HY
Differential in normal mode (energy saving mode not active):
(0.1 to 25.0°C; 1 to 45°F)
differential for set point. Compressor Cut-IN is
[SET-POINT + HY]
. Compressor Cut-OUT is when the temperature reaches the set point.
HYE
Differential when energy saving mode is active:
(0.1 to 25.0°C; 1 to 45°F) differential for set
point. Compressor Cut-IN is
[SET-POINT + HES + HYE]
. Compressor Cut-OUT is when the
temperature reaches the
[SET-POINT + HES]
.
odS
Outputs delay activation after power on:
(0 to 255 min) this function is enabled after the
power-on of the instrument and inhibits any output activation for the period of time set in the
parameter.
AC
Anti-short cycle delay:

following restart.
Rtr
P1-P2 percentage for regulation:
100=P1 only; 0=P2 only
CCt
Maximum duration for pull down:
(0.0 to 23h50min, res. 10min) after elapsing this interval of
time the super cooling function is immediately stopped
CCS
Differential for pull down:
(-12.0 to 12.0°C; -21 to 21°F) during any super cooling phase the
regulation SETPOINT is moved to
SET+CCS
(in normal mode) or to
SET+HES+CCS
(in
energy saving mode)
oHt
Overheating before activating the pull down function (when in normal mode):
(1.0 to
12.0°C; 1 to 21°F) this is the upper threshold limit used to activate the super cooling function.
oHE
Overheating before activating the pull down function (when in energy saving mode):
(1.0
to 12.0°C; 1 to 21°F) this is the upper threshold limit used to activate the super cooling
function.
Con
Compressor ON time with faulty probe:
(0 to 255 min) time during which the compressor is
active in case of faulty thermostat probe. With
CY=0
compressor is always OFF.
CoF
Compressor OFF time with faulty probe:
(0 to 255 min) time during which the compressor is
OFF in case of faulty thermostat probe. With
Cn=0
compressor is always active.
PROBE SETUP
ot
Thermostat probe calibration:
(-12.0 to 12.0°C; -21 to 21°F) allows to adjust any possible
offset of the first probe.
P2P
Evaporator probe presence:
n
= not present;
Y
= the defrost stops by temperature.
