Parameters related to adjustment
Hy - tolerance (0.1
O
C ~ 25
O
C / 1
O
F ~ 45
O
C) - operating temperature tolerance. A product’s compressor will start when the
temperature reaches the sum of operating temperature plus the tolerance. The compressor will turn off when the temperature
equals the set operating temperature.
LS - minimum temperature (from -55
O
C / -67
O
C) - minimum operating temperature.
US - maximum operating temperature (up to 99
O
C / +99
O
F) - maximum operating temperature.
Note! Both of the above parameters should not be set beyond the range mentioned in the user manual and visible on the product
nameplate.
ot - fi rst sensor calibration (-9.9 ~ +9.9
O
C / -17 ~ +17
O
F) - it allows setting the fi rst sensor temperature off set .
P2 - presence of evaporation sensor - n = - absent; y = - present.
oE - second sensor calibration (-9.9 ~ +9.9
O
C / -17 ~ +17
O
F) - it allows setting the second sensor temperature off set .
od - output activation delay during the start-up (0 - 99 min.) - parameter determines the delay time of output activation after starting
the instrument.
AC - compressor operation cycle (0 - 50 min.) - time between stopping and re-starting the compressor operation.
Cy - switching on the compressor with defective sensor (0 - 99 min.) - time of compressor operation in case of the defective
thermostat sensor. In case of Cy = 0 setting, the compressor is always on.
Cn - switching off the compressor with the defective sensor (0 - 99 min.) - time when the compressor is switched off in case of the
defective thermostat sensor. In case of Cy = 0 setting, the compressor is always switched off .
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 off ; 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 diff 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 off during defrosting; on = fans
continuous operation, switched off 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 off temperature (-50 ~ +50
O
C / -67 ~ +99
O
F) - sets the temperature, of evaporator sensor, above which the fans
will be switched off .
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.
