Hy Dierential
(0,1 ÷ 25,5°C / 1÷255 °F) Intervention
dierential for set point. Compressor
Cut IN is Set Point + dierential (Hy).
Compressor Cut OUT is when the
temperature reaches the set point
Pr1 1~ 45 3 3 3
LS Minimum set point
(- 50°C÷SET/-58°F÷SET): Sets the
minimum value for the set point..
Pr2

US Maximum set point
(SET÷110°C/ SET÷230°F). Set the
maximum value for set point.
Pr2 SET ~ 302F

Ot
Thermostat probe
calibration
(-12.0÷12.0°C; -120÷120°F) allows
to adjust possible oset of the
thermostat probe

OdS
Outputs activation
delay at start up
(0÷255min) 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

COF
Compressor OFF
time with faulty
probe
(0÷255 min) time during which the
compressor is OFF in case of faulty
thermostat probe. With COF=0

hot gas defrost
EL EL EL
dtE
Defrost termination
temperature
(-50÷50 °C/ -58÷122°F) (Enabled only
when EdF=Pb) sets the temperature
measured by the evaporator probe,
which causes the end of defrost
Pr1 -58~122 65 65 38
IdF
Interval between
defrost cycles
(0÷120h) Determines the time
interval between the beginning of
two defrost cycles
Pr1 0 ~ 120 hours 6 6 6
MdF
(Maximum) length
for defrost
(0÷255min) When P2P = n, (not
evaporator probe: timed defrost) it
sets the defrost duration, when P2P =
y (defrost end based on temperature)
it sets the maximum length for defrost

Fdt Drip time
(0÷120 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
