2. PARAMETERS
REGULATION
Hy Differential: (0,1°C ÷ 25°C / 1°F ÷ 45°F) Intervention differential for set point. Compressor Cut IN is SET POINT + differential (Hy). Compressor Cut OUT
is when the temperature reaches the set point.
LS Minimum SET POINT: (-55°C÷SET/-67°F÷SET): sets the minimum value for the set point.
US Maximum SET POINT: (SET÷99°C/ SET÷99°F): sets the maximum value for set point.
ot First probe calibration: (-10÷10°C / -17°F ÷ 17°F): through this parameter it is possible to correct any possible reading errors due to the excessive length
of the cable of the probe 1.
P2 Evaporator probe presence: n= not present; y= the defrost stops by temperature.
oE Second probe calibration: (-10÷10°C / -17°F ÷ 17°F): through this parameter it is possible to correct any possible reading errors due to the excessive
length of the cable of the probe 2.
od Outputs activation delay at start up: (0÷99min) This function is enabled at the initial start up of the instrument and inhibits any output activation for
the period of time set in the parameter.
AC Anti-short cycle delay: (0÷50 min) minimum interval between the compressor stop and the following restart.
Cy Compressor ON time with faulty probe: (0÷99 min) time during which the compressor is active in case of faulty thermostat probe.
With Cy=0 the compressor is always OFF. Note: If Cy=0 and Cn=0 the compressor remains OFF.
Cn Compressor OFF time with faulty probe: (0÷99 min) time during which the compressor is OFF in case of faulty thermostat probe.
With Cn=0 compressor is always on.
DISPLAY
CF Measurement unit: (°C÷°F) °C= Celsius; °F= Fahrenheit.
WARNING: When the measurement unit is changed the SET point and the values of the parameters Hy, LS, US, oE, o1, AU, AL have to be checked and
modified if necessary.
rE Resolution (only for °C): (dE ÷ in) dE= decimal between -9.9 and 9.9 °C; in= integer.
Ld Default display: (P1 ÷ P2) P1= thermostat probe; P2= evaporator probe.
dy Display delay: (0÷15 min.) when the temperature increases, the display is updated of 1 °C/1°F after this time.
DEFROST
td Defrost type: (EL – in) EL= electrical heater, compressor OFF; in= hot gas, compressor ON;
dE Defrost termination temperature: (-55÷50°C / -67÷99°F) if dE= Pb it sets the temperature measured by the evaporator probe,
which causes the end of defrost.
id Interval between defrost cycles: (0÷99 minutes) Determines the time interval between the beginning of two defrost cycles.
Md Maximum length for defrost: (0÷99 min. with 0 no defrost) when P2= n, (not evaporator probe: timed defrost) it sets the defrost duration,
when P2= y (defrost end based on temperature) it sets the maximum length for defrost.
dd Start defrost delay: ( 0÷99min) This is useful, when different defrost start times are necessary, to avoid overloading the plant.
dF Display during defrost: (rt / it / SP / dF) rt= real temperature; it= start defrost temperature; SP= SET-POINT; dF= label dE.
dt Drip time: (0÷99 min) time interval between reaching defrost termination temperature and the restoring of the control's normal operation.
This time allows the evaporator to eliminate water drops that might have formed due to defrost.
dP Defrost at power – ON: (y÷n) y= at power on defrost starts; n= defrost doesn't start at power-on.
FANS
FC Fans operating mode: (cn, on, cY, oY) cn= runs with the compressor, OFF during defrost; on= continuous mode, OFF during defrost; cY= runs with the
\compressor, ON during defrost; oY= continuous mode, ON during defrost.
Fd Fans delay after defrost: (0÷99 min) Interval between end of defrost and evaporator fans start.
FS Fans stop temperature: (-55÷50°C/-67°F ÷ 99°F) setting of temperature, detected by evaporator probe, above which fans are always OFF.
ALARMS
AA 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 set point. Temperature alarm is enabled when the temperature exceeds the "SET+ALU" or "SET-ALL" values.
AU Maximum temperature alarm: (AL÷99°C/99°F) when this temperature is reached the alarm is enabled, after the "Ad" delay time.
AL Minimum temperature alarm: (-55÷AU°C /-55÷AU°F) when this temperature is reached the alarm is enabled, after the "Ad" delay time.
Ad Temperature alarm delay: (0÷99 min) time interval between the detection of an alarm condition and alarm signalling.
