1 INTRODUCTION
1.1 Introduction
EVBOX1 is a line of front mounted electrical boards for the
management of cold rooms with single-phase compressor.
The user interface comprises a large custom display (with
decimal point and function icons), six keys, and has a
guaranteed IP65 protection grade front part.
The boards are equipped with two 30A res. @ 250 VAC relays
for the direct control of high power compressors and
defrosting elements, with no need for remote control switches.
They can operate in conditions of both low and high relative
humidity percentages, have an adaptive management of the
defrost function, and can implement energy-saving strategies.
Some models are also equipped with a magneto-thermal
switch or different ial magneto-thermal circuit breaker, a clock
(to save the HACCP alarms), management of defrosting
elements and have an integrated driver for unipolar stepper
electronic expansion valves.
The unit is designed to be wall mounted, with bolts and
fastening screws.

4.7 Insertion of the RS-485 MODBUS port termination resistor
To reduce reflections on the signal transmitted through the cables connecting the devices to a RS-485 network it is necessary to insert
the termination resistor of the first and last elements of the network.
To insert the termination resistor place the jumper as shown in the following drawing.
4.8 Connection of the RS-485 network cable screen to GND
To prevent external disturbances from being interpreted as signals by the RS-485 network, it might be necessary to connect the cable
screen of the RS-485 network to GND
To connect the cable screen to GND, place the jumper as shown in the following drawing.
4.9 Warnings for the electric connection
- do not use electric or pneumatic screwdrivers on the device terminal board
-
if the device has been taken from a cold to hot place, humidity could condense inside; wait about 1 hour before powering it
make sure that the power supply voltage, the frequency and the operational electric power of the device, correspond with
-
those of the local power supply; see chapter “TECHNICAL DATA”
-
disconnect the device power supply before proceeding with any type of maintenance
connect the device to a RS-485 MODBUS network using a twisted pair
-
-
position the power cables as far away as possible from the signal cables
for repairs and information regarding the device, contact the EVCO sales network.

“on” state (the device is powered and is on: the
regulators can be switched on)
“stand-by” status (the device is powered but is
-
switched off via software: the regulators are
switched off; the possibility to turn the room light
or the auxiliary output on/off manually depends on
parameter u2)
-
the “off” status (the device is not powered).
Hereafter, with the word “start-up” means the passage from
“stand-by” status to “on” status; the word “shutdown” means
the passage from “on” status to “stand-by” status.
When the power is switched back on, the device displays the

"Rapid cooling" function enabling/disabling
Page 26
EVCO S.p.A. EVBOX1 | Installation guide ver. 1.2 | Code 144BOX1E124
During the "rapid cooling" function the work set point is
decreased by the temperature set with the r5 parameter; the
function runs for the span of time set with the r6 parameter.

7 OPERATION WITH LOW OR
HIGH RELATIVE HUMIDITY
PERCENTAGES (ONLY IF THE F0
PARAMETER IS SET TO 5)
7.1 Preliminary notes
During operation with a low relative humidity percentage, the
evaporator fan shall be turned on if the compressor is on, and
shall turn on cyclically if the compressor is off (the F4
parameter determines the duration of the off phase of the fan
and the F5 parameter determines the on phase).
During operation with a high relative humidity percentage, the
evaporator fan is always on.
7.2 Manual activation of the low
and high relative humidity
percentages operating mode
To activate the the low or high relative humidity percentages
operating mode manually, proceed as follows:
1.
Ensure that the device is on, the keypad is not
locked and that no procedure is in progress.
2.
Keep the "SET" and "UP" keys pressed for
4 s: the letters "rhL" (operation with low relative
humidity percentage) or "rhH" (operation with
high relative humidity percentage) shall be
displayed on screen for 10 s.
To restore the normal display before time:
Press any key.
3.
It is also possible to activate the low or high relative humidity
percentage operation mode with the F6 parameter.
If the F0 parameter is not set to 5, pressing the keys shall
make the message "- - -" appear on display for 1 s.

8 “ENERGY SAVING” FUNCTION
8.1 Preliminary notes
Once the time you have set with parameter i10 has passed,
without activations of the door micro switch input (after the
room temperature has reached the work set point) the
“energy saving” function is activated (until the input is
activated again).
During the “energy saving” function, the work set point is
increased by the temperature established with parameter r4
and the evaporator fan is turned on cyclically, provided that
the F0 parameter is set to 1, 2, 3 or 4 (parameter F13
establishes the duration of fan switch off and parameter F14
that of switch on).
It is also possible to activate the “energy saving” function in
remote mode through the digital inputs (with effect only on
the compressor).
9 “CPT” FUNCTION
(CALCULATED PRODUCT
TEMPERATURE)
9.1 Preliminary notes
If parameter P4 is set at 4, the temperature associated to the
regulation will mainly depend on the temperature detected by
the inlet air probe and that detected by the air outlet probe,
herein called CPT temperature (Calculated Product
Temperature); the room temperature probe shall operate as
an air inlet temperature probe and the auxiliary temperature
probe as an air outlet temperature probe.
The formula for the calculation of the CPT temperature is:
CPT temperature = {[(value established with parameter P7) x
(temperature detected by the inlet air probe)] : 100} +
{[(100 - value established with parameter P7) x (temperature
detected by the outlet air probe)] : 100}.
10 “HACCP” FUNCTION
10.1 Preliminary notes
The device can memorise the following HACCP alarms:
-
minimum temperature alarm (code “AL”)
maximum temperature alarm (code “AH”)
-
door micro switch input alarm (code “id”)
-
-
power supply cut-off alarm (code “PF”; only in the
models with clock).
The device can memorise up to 9 alarms, after which the
oldest alarm is overwritten.
The device supplies the following information for every alarm:
- the crit ical value
the date and time at which the alarm occurs (only
-
in the models with clock)
-
the duration of the alarm (from 1 min to 99 hours
and 59 min, partial if the alarm is in progress).
The following table shows the correspondence between the
alarm codes and the relevant critical values.
CODE CRITICAL VALUE
AL
AH
id
PF
Models without clock update the information regarding the
alarms provided the critical value of the new alarm is more
critical than that stored or provided the informat ion has
already been displayed.
If the device is switched off, no alarms will be stored.
The “HACCP” LED provides information regarding the storage
status of the alarms; see paragraph “Signals”.

sec, after which the device will exit the procedure
10. Cut the device power supply off.
To exit the procedure in advance:
11. Hold the “UP” and “DOWN” key for 4 s during the
procedure (i.e. before setting “1”: Restore will not
be performed).
Make sure that the manufacturer’s settings are appropriate
(see paragraph 12.5 “List of configuration parameters”.
