WARNING: When first connected, easy is already on and ready to be used. The instrument can be switched on from a supervisor PC and via an external contact (setting A4= 5). The latter has priority over the other modes.
SET POINT SETTING (DESIRED TEMPERATURE VALUE)
The easy and easy compact devices control the desired temperature (set point) inside the cabinet or cold room directly and dynamically.
To view and modify the set point:
•press SET for 1 s, the set value will start flashing;
•increase or decrease the value using UP or DOWN;
•press SET to confirm the new value.

| Press DOWN for more than 3 s (activated only if the temperature | |
| conditions are right). | |
|
| |
| CONTINUOUS CYCLE | |
| Press UP+DOWN for more than 3 s (activated only if the temperature | |
| conditions are right). | |
| The continuous cycle is used to maintain refrigeration active in the | |
| cabinet or cold room, regardless of the temperature inside the unit. | |
| This may be useful for rapidly bringing the temperature below the | |
| set point value. | |

| RAPID DISPLAY OF THE TEMPERATURE READ BY THE OTHER | |
| PROBES | |
| Press the DOWN button to scroll the temperatures read by the | |
| probes. Each time the DOWN button is pressed, the display will | |
| show the name of the probe Pr1, Pr2 or Pr3 (only on the models | |
| with 3 inputs and with multifunction input configured as a probe) | |
| and after 1 s the temperature measured by the selected probe will | |
| be displayed. | |
| To display the other probes, press DOWN again. | |
| To return to the normal display, wait 3 s without pressing any | |
| buttons (exit by timeout). |
Temperature Display
The temperature displayed, the unit of measure and the decimal resolution can be set according to the following parameters: /4, /5 and /6.
/4 : select probe displayed
Used to choose whether to display the temperature read by the control probe (Probe 1), Probe 2 or the status of the multifunction input (analogue or digital).
Parameter /4 selects the probe shown on the display, all the other display and control modes remain unchanged.
IMPORTANT: the easy compact models can display up to 2 probes.
Installation and Operations Manual
/5: select °C/°F
Defines the unit of measure used for temperature control. /5=0 to work in °C
/5=1 to work in °F.
WARNING:
when changing from one unit of measure to the other, all the values of the temperature parameters are modified to the new unit of measure.
The max and min limits of the absolute temperature parameters are the same for both °C that °F. The range of temperatures allowed is therefore different between °C and °F:
/6: disable decimal point
Used to enable or disable the temperature display with the resolution to the tenths of a degree between
/6= 0 temperature displayed to the tenth of a degree;
/6=1 temperature displayed without the tenths of a degree.
NOTE: the decimal point is only disabled in relation to the reading shown on the display (the calculations performed by the controller remain unchanged).
Temperature Control
The following parameters are used to control the temperature: St, r1, r2, r3, r4 and rd.
St: set point, r1 minimum value and r2 maximum value of the set point
Parameter St determines the desired temperature to be maintained inside the cabinet or cold room (set point). Parameters r1 (minimum value) and r2 (maximum) set the range of temperatures for setting the set point.
NOTE: the set point can be set by pressing the SET button (see par. “Setting the set point (desired temperature value)” page 11).
r3: select direct/reverse operation
Defines the operating mode of the device:
•r3=0: direct with defrost. Used to request the activation of the compressor when the temperature measured by probe 1 rises above the set point. This mode also includes defrost
•r3=1: direct without defrost
•r3=2: reverse without defrost. Used to request the activation of the compressor when the temperature measured by probe 1 falls below the set point. This mode does NOT include defrost.
