Display parameters
CF - measuring unit ( O C / O F) - unit of temperature measure, O C - degrees Celsius, O F - degrees Fahrenheit. Note! After the change
of a temperature unit, check and if necessary change the settings of the following parameters: Hy, LS, oE, o1, AU, AL.
rE - resolution (only for
O
C) - dE ÷ in - decimal part between -9.9 and 9.9
O
C; in = integer part
Ld - default display (P1 ÷ P2) P1 = thermostat sensor; P2 = evaporator sensor; SP - set temperature
dy - display delay (0 - 15 min.) - time after which the display changes by 1 O C / 1 O F when temperature rises.
Defrosting parameters
td - defrosting type (EL - in) - EL = electric heater, compressor o ff ; in = hot gas, compressor on
dE - frosting end temperature (-50 ~ +50 O C / -67 ~ +99 O F) if P2 = y - sets the temperature measured by the evaporator sensor,
which completes the defrosting process.
id - time interval between defrosting processes (0-99 min.) - determines the time between the beginnings of two defrosting
modes.
Md - maximum defrosting time (0-99 min whereas 0 means no defrost) - in case P2 = n, sets the duration of defrosting, in case P2
= y, this parameter indicates the maximum duration of defrosting.
dd - defrosting start delay (0-99 min.) - a useful parameter when it is necessary to di ff erentiate the start time of defrosting proc-
esses in order to avoid the mains overload.
dF - display during defrosting (rt / it / SP / dF) - rt = actual temperature; it = defrosting start temperature; SP = set temperature;
dF = dF label.
dt - condensation time (0-99 min.) - time interval between reaching the defrosting end temperature and restoring the normal
control operation. Time to remove drops of water that might have formed during defrosting process.
dP - defrost during the start-up (y / n) - y = defrosting process will be performed after starting; n = defrosting will not be performed
after starting.
Parameters for fans
FC - fan operation mode (cn, on, cY, oY) - cn = fans started during compressor operation, turned o ff during defrosting; on = fans
continuous operation, switched o ff during defrosting; cY = fans started during compressor operation, switched on during defrost-
ing; oY - continuous fans operation, switched on during defrosting.
Fd - delay after defrosting (0-99 min.) - time interval between the end of defrosting and starting the fans.
FS - fan switch o ff temperature (-50 ~ +50 O C / -67 ~ +99 O F) - sets the temperature, of evaporator sensor, above which the fans
will be switched o ff .
Alarm parameters
AU - maximum temperature alarm (AL ÷ 99 O C / 99 O F) - if the temperature set by this parameter is reached, the alarm will be
activated after the time set by the Ad parameter.
AL - minimum temperature alarm (-55 ÷ AU
O
C / -67
O
F) - if the temperature set by this parameter is reached, the alarm will be
activated after the time set by the Ad parameter.
Ad - temperature alarm delay (0-99 min.) - time interval between the occurrence alarm activation conditions and its signalling.
dA - temperature alarm delay after starting (0-99 min.) - time interval between the occurrence alarm activation conditions and its
signalling after the start-up of the product.
Digital input parameters
iP - digital input polarity (oP ÷ cL) oP = activated by contact activation; cL = activated by contact deactivation.
iF - digital input con fi guration (EA / bA / do / dF / Au / Hc) - EA = external alarm; “EA” message is displayed; bA = serious alarm,
“CA” message is displayed; do = door connector function; dF = defrosting activation; Au = unused; Hc - action reversal.
di - digital input delay (0-99 min.) - if iF = EA or iF = bA determines the time interval between the detection of an external alarm
and its signalling; if iF = do determines the delay for door opening alarm.
dC - condition of compressor and fans in case the door is open (no / Fn / cP / Fc) no = normal; Fn = fans o ff ; cP = compressor
o ff ; Fc - compressor and fans o ff .
rd - adjustments with the door open (n ÷ y) - n = no adjustment if the door is open; Y = if the time set by means of “di” parameter
elapses, adjustment will restart even if the door open alarm is activated.
Other parameters
d1 - display of thermostat sensor (reading only)
d2 - display of evaporator sensor (reading only)
Pt - array of parameter codes
rL - software version
Placing of foodstu ff s in product’s refrigeration chamber
It is not necessary to switch o ff the product while placing and removing foodstu ff s in the refrigeration chamber. However, make
