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.
MANUAL DEFROST
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.
/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 dierent 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 -20 and + 20
(easy) or -10 and +10 (easy compact).
/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.
