1.5 Setting and changing the set point: The procedure is the same as described for the single-temperature control unit. The only difference is the

possibility of switching on/off each individual evaporator using the corresponding on/off button. In addition defrost always takes place at the same time in both evaporators; if an evaporator completes its

defrost cycle in a shorter time than the other, it remains in stand-by mode until the second evaporator ends its cycle. The cold mode of an evaporator prevails over the hot mode of the other one. No conflicting operation is allowed: both evaporators can only operate in the same mode (that is both in cold or hot mode, or they stop when the corresponding set temperature has been reached). 2. Operation 2.1 Operation in road mode:

Check that the punctiform LED on the display is on, showing that the unit is on. Start the vehicle engine and press the ON button for 3 seconds. Attention: when the vehicle is not in motion the refrigerating unit can not be used in road mode. The operation and road icons light up.

To stop the refrigerating unit press the on/off button or stop the vehicle. 2.2. Operation in stand-by mode:

Check that supply voltage corresponds to the one shown in the data plate (tolerance: +/-10% on nominal voltage), then insert the plug.

Press the ON button for 3 seconds: the operation and standby icons light up; the red display shows the cold room temperature and the yellow display the set point. To stop the refrigerating unit press the on/off button. 2.3. Automatic operation:

After starting the unit operates automatically and it stops any time the cold room temperature reaches the set point; it resumes operation when temperature reaches a value corresponding to set point + differential.

According to the model, the refrigerating unit can show different operating modes which give rise to the activation of different icons:

- cold mode: activated icons - -

- hot mode: activated icons -

In addition to these icons the road or standby icon, or , will also be activated.

2.4. Defrost: The defrost cycle is activated automatically at intervals, or manually by pressing the defrost button. During

this cycle the icons and light up. In the operating mode with heat pump, evaporator and condenser exchange their functions; for this reason

the icons activating during defrost can also be and , depending on the defrost cycle involving the evaporator or the condenser.

In the operating mode with heat pump the defrost cycle ends by time out. 2.5 Alarms and warnings Low pressure switch alarm When the low pressure switch trips, the unit stops: the alarm LED lights up and the label PRL is displayed. Reset is automatic. If the number of interventions is higher than parameter LPn during the time set by parameter LPd, the alarm PMI is produced. This alarm can only be reset by switching the unit off and on again. High pressure switch alarm When the high pressure switch trips, the unit stops: the alarm LED lights up and the label PRH is displayed. Reset is automatic. If the number of interventions is higher than parameter HPn during the time set by parameter HPd, the alarm PMS is produced. This alarm can only be reset by switching the unit off and on again. Overload relay alarm This alarm is only active when the unit operates in standby mode. When the relay or the thermistor trips, the unit stops. The alarm LED lights up and the label F1t is displayed. Regulation is resumed after reset and a time Htt. If the number of interventions is higher than parameter Htn during the time set by parameter Htd, the alarm FTB is produced. This alarm can only be reset by switching the unit off and on again. Sensor failure alarm Label E01 is displayed and the alarm LED is activated. The unit stops.

High/Low temperature alarm Alarms are produced when the actual temperature goes out of a certain range determined on the basis of the set point. In case of low temperature the alarm LED lights up and LA is displayed; in case of high temperature the alarm LED lights up and HA is displayed. Battery voltage alarm This alarm is only active when the unit operates in road mode. If battery voltage (sensored on key introduction) is lower than the value bt-Pab, a preliminary alarm PAb is activated which just indicates that there is an anomaly. Should voltage drop down to a value corresponding to bt-Ab, the battery alarm AB is produced and the unit is stopped. In addition to above labels the battery icon is activated. The unit resumes operation after voltage has reached its correct value and time bb has elapsed. Supply alarm This alarm is produced when both road and standby signals are present. The alarm stops the refrigerating unit; ALM is displayed and the standby and road icons flash.
