Description
Cut-out temperature
Intervention differential for set point. When the
temperature ≥SP+dF, compressor Cut IN , when
the temperature ≤SP, compressor Cut OUT.
Set the minimum value for the set point.
Set the maximum value for set point.
Allow to adjust possible offset
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.
Minimum interval between the compressor stop
and the following restart.
Time during which the compressor is active in
case of faulty thermostat probe.
Time during which the compressor is OFF in case
of faulty thermostat probe.
°C =Celsius; °F =Fahrenheit. WARNING: When
the measurement unit is changed the set point
SP and the values of the parameters dF. LL. UL.
AH. AL etc have to be checked and modified if
necessary.
Only for °C, dE= decimal between -9.9 and
9.9°C; in= integer
when the temperature increases, the display is
updated of 1 °C/1°F after this time.
Determine the time interval between the begin-
ning of two defrost cycles.
Set the maximum length for defrost,with 0 no
defrost
rt= real temperature; it= start defrost tempera-
ture;SP= set point SP; dF= label dF.
When this temperature is reached, the alarm is
enabled after the "A1" delay time.
When this temperature is reached, the alarm is
enabled after the "A1" delay time.
Time interval between the detection of an alarm
condition and alarm signalling.
Time interval between the detection of the tem-
perature alarm condition after instrument power
on and alarm signalling.
