Parameters Description - Zanotti uniblock SB-SP O Instructions

TEMPERATURE PROBE SETTING
C
: CALIBRATION
It allows to add an offset to the measured value . It is active only with the environment probe,
while the evaporator probe cannot be calibrated.
2
: DIGITAL FILTER
It allows to define the coefficient used in the digital filter of the measured value. High values for this
parameter allow to reduce the noise present in the input lines ( but the measure operation is
slower) . The suggested value is 4..
3
: INPUT LIMITATION
It allows to define the maximum range of the measure in a machine cycle. Low values of the
parameter allow to threshold the maximum variation of the measure, removing impulsive noise
or spikes. The suggested value is 8.
4
: VIRTUAL PROBE
The value used for regulation is an average of the value measured by the temperature probe and
of the value measured by the defrost probe.
5
: CELSIUS/FAHRENHEIT
It allows to choose the operating temperature scale
6
: DECIMAL POINT
It allows to enable the decimal point in the range -9.9 to 19.9. (0=NO, 1=YES).
rd
: REGULATION DELTA
It defines the temperature differential used in the temperature set-point..
r1
: MINIMUM SET ALLOWED
Defines the lower bound when tuning the set-point of the device.
r2
: MAXIMUM SET ALLOWED
Defines the upper bound when tuning the set-point of the device.
r3
: DIRECT / REVERSE
Enables or disables the Ed alarm display (defrost stopped for time-out). The alarm is handled
anyway to allow the supervisor to detect it.
r4
: CURTAIN SET-POINT DELTA
It defines the variation of the set-point when operating with the curtain closed.
r5
: MAXIMUM AND MINIMUM ENABLE
It enables or disables the display of the environment probe maximum value rH and of the minimum
value rL measured in the rt time.
rt
: MONITORING INTERVAL
It defines , in hours, the temperature monitoring time interval during which the parameters rH and rL are updated.
During the rt parameter display, pressing the down key it is possible to force a timer reset, setting
automatically rH = rL = Temperature.
rH e rL parameters reset occours also when rt timer reaches its maximum value.
rH
: MAXIMUM TEMPERATURE MEASURED DURING RT
Shows the maximum temperature measured by the environment probe during the time interval rt.
