After 2 sec the display will show the first group label (rEG) with a blinking PRG icon to indicate that protected
parameters now are editable.
5. PARAMETER TABLE
Here are the descriptions of the device parameters.
5.1 PARAMETER DESCRIPTION
5.1.1 Main regulation parameters - rEG
SEt
Set Point: range from LS to US
LS
Minimum Set Point: (-100.0°C to SET; -148°F to SET) fix the minimum value for the set point.
US
Maximum Set Point: (SET to 200.0°C; SET to 392°F) fix the maximum value for the set point.
HY
Compressor regulation differential in normal mode: (0.1 to 25.0°C; 1 to 45°F) set point
differential. Compressor Cut-IN is T > SET + HY. Compressor Cut-OUT is T<=SET.
HYE
Compressor regulation differential in energy saving mode: (0.1 to 25.0°C; 1 to 45°F) set point
differential. Compressor Cut-IN is T > SET + HES + HYE. Compressor Cut-OUT is T<= SET + HES.
odS
Output activation delay at start-up: (0 to 255 min) this function is enabled after the instrument
power-on and delays the output activations.
AC
Anti-short cycle delay: (0 to 50 min) minimum interval between a compressor stop and the
following restart.
rtr
Regulation percentage=F(P1; P2) (100=P1; 0=P2): 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
Pull Down phase differential (SET+CCS or SET+HES+CCS): (-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
Threshold for automatic activation of Pull Down in normal mode (SET+HY+oHt): (1.0 to 12.0°C;
1 to 21°F) this is the upper limit used to activate the super cooling function.
oHE
Threshold for automatic activation of Pull Down in energy saving mode
(SET+HES+HYE+oHE): (1.0 to 12.0°C; 1 to 21°F) this is the upper 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.
5.1.2 Probe configuration parameters – Prb
ot
Probe P1 calibration: (-12.0 to 12.0°C; -21 to 21°F) allows to adjust any possible offset of the first
probe.
P2P
Probe P2 presence: n = not present; Y = present.
oE
Probe P2 calibration: -12.0 to 12.0°C; -21 to 21°F) allows to adjust any possible offset of the
second probe.
P3P
Probe P3 presence: n = not present; Y = the defrost present.
o3
Probe P3 calibration: (-12.0 to 12.0°C; -21 to 21°F) allows to adjust any possible offset of the third
probe.
P4P
Probe P4 presence: n = not present; Y = present.
o4
Probe P4 calibration: (-12.0 to 12.0°C; -21 to 21°F) allows to adjust any possible offset of the forth
probe.
5.1.3 Visualization parameters - diS
CF
Temperature measurement unit: (°C; °F) °C = Celsius; °F = Fahrenheit.
rES
Temperature resolution: (dE; in) dE = decimal; in = integer.
Lod
Probe default displayed: (P1; P2; P3; P4; SEt; dtr; USr) Px=probe “x”; SEt=set point; dtr=do not
use it.
