Adjustment parameters
St – the value of the set temperature
Hy – tolerance (0,1°C ~ 10°C/1°F ~ 25°C) – operating temperature tolerance. The product compressor will start when the tem-
perature reaches the sum of the operating temperature and tolerance. The compressor switches off when the temperature equals
the set operating temperature.
LS – minimum temperature (from -50°C/-50°F) – minimum operating temperature.
US – maximum operating temperature (up to +99°C/+99°F) – maximum operating temperature.
Note! Both of the above parameters should not be set outside the range specifi ed in the user manual and visible on the product
nameplate.
ot – calibration of the fi rst sensor (-9.9 ~ +9.9°C/-20 ~ +20°F) – allows setting the temperature off set of the fi rst sensor.
P2 – presence of evaporation sensor – n - not present; y - present.
oE – calibration of the second sensor (-9,9 ~ +9,9°C/-20 ~ +20°F) – allows you to set the temperature off set of the second sensor.
od – delay of output activation during start-up (0 – 99 min.) – the parameter defi nes the delay time of the output after starting the
instrument.
AC – compressor cycle (0 – 50 min.) – the time between stopping and resuming the operation of the compressor.
Cy – switching on the compressor with a faulty sensor (0 – 99 min.) – the time in which the compressor is started in case of a
defective thermostat sensor. In case of Cy = 0 the compressor is always on.
Cn – compressor shutdown with faulty sensor (0 – 99 min.) – the time in which the compressor is switched off in case of a dam-
aged thermostat sensor. In case of Cy = 0 the compressor is always switched off .
CH – equipment operation mode: heating or cooling: CL – cooling; Ht – heating.
Display parameters
CF – measurement unit (°C/°F) – temperature measurement unit °C – degrees Celsius, °F – degrees Fahrenheit.
Ld – default display (P1 ÷ P2) P1 - thermostat sensor; P2 - evaporator sensor; SP – set temperature
Defrost parameters
dE – defrost end temperature (-50 ~ +90°C/-50 ~ +90°F)
id – interval between defrosting processes (0-99 h) – specifi es the time between the start of two defrost modes.
Md – maximum defrosting time (1-99 min.)
dF – display during defrosting (rt/it/St/dF) – rt = actual temperature; it = defrost start temperature; St = set temperature; dF = label
dF.
Alarm parameters
AU – maximum temperature alarm (AL+1) ÷ 99°C/99°F) – if the temperature set by this parameter is reached, the alarm will be
triggered after the time set by the parameter Ad.
AL – minimum temperature alarm (-50°C ÷ (AU-1)/-50°F ÷ (AU-1)) – if the temperature set by this parameter is reached, the alarm
will be triggered after the time set by the parameter Ad.
Ad – temperature alarm delay (0-99 min.) – the time interval between the occurrence of alarm activation conditions and its acti-
vation.
dA – temperature alarm delay after the start-up (0-99 min.) – the time interval between the occurrence of alarm activation condi-
tions and its activation after starting the product.
Alarm messages
P1 – thermostat sensor failure – the compressor operates according to the settings of Cy and Cn parameters.
P2. – evaporator sensor failure – defrost relay operates between id and Md parameters.
HA – high temperature alarm – the output remains unchanged.
LA – low temperature alarm – the output remains unchanged.
LP – no access to the evaporator sensor – the display shows the evaporator temperature.
Er – program failure – check that all parameters have been correctly programmed.
Control panel operation (Dixell)
The product has been fi tted with a control panel that allows operators adjusting temperature inside the display case and starting
the manual defrosting process.
Arrows are used for setting the temperature, the one pointing upward increases the temperature, and the one pointing downward
decreases it.
The display shows the temperature measured by means of sensors placed inside the product. Temperature can be set within the
range given in the technical data table and on the product nameplate.
