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 differential 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.

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 (CALCULAT-
ED 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}.

the unit of measurement depends on P2
Properly set the parameters corresponding to the regulators after setting parameter P2
The formula for the calculation of the CPT temperature is:
CPT temperature = {[(P7) x (temperature detected by the inlet air probe)] + [(100 - P7) x (temperature detected by the outlet air probe)] : 100}
the unit of measurement depends on P9 and P10
the value depends on parameter P2 (0,1 °C or 1 °F)
if parameter r12 is set to 0, the compressor will be switched on when the room temperature or CPT temperature is above the "working set-point + r0" and will be switched off when the
temperature falls below the working set-point; if parameter r12 is set to 1, the compressor will be switched on when the room temperature or CPT temperature is above the “working set-point
+ r0/2” and will be switched off when the temperature falls below the "working set-point - r0/2”

the choice of which compressor to switch on/off depends on parameters C12 and C13
the parameter has effect even after an interruption in the power supply that occurs while the device is switched on
the time established with the parameter is counted even when the device is switched off
if parameter C1 is set at 0, the delay after the end of the room temperature/inlet air proble error will be 2 min
the parameter differential is 2,0 °C/4 °F
if when the device is switched on, the condenser temperature is already above that established in parameter C7, then parameter C8 will not have effect
the device memorises the defrosting interval count every 30 minutes; the setting of parameters d0 and d26 has effect from the conclusion of the previous defrosting interval or the activation of
defrosting in manual mode
the display restores normal operation when, on conclusion of evaporator fan standstill, the room temperature or CPT temperature drops below that which has blocked the display (or if a
temperature alarm occurs) the value of ∆t depends on parameter r12 (r0 if r12 = 0, r0/2 if r12 = 1)
if parameter P3 is set at 0 or 2, the device will function as if parameter d8 were set at 0
if when defrosting is activated, the operating duration of the compressor is less than the time established with parameter d5, the compressor will remain on for the amount of time necessary to
complete defrosting
if parameter d8 is set at 2 or 3, the device will operate as if the parameter as been set at 0 and defrosting will be activated when the device has been on totally for the time established with
parameter d26
if parameter P3 is set at 0, the device will function as if parameter A0 were set at 0 but it will not store the alarm
during defrosting and dripping and when the evaporator fan is stopped, the temperature alarms are absent, provided that these were signalled after the activation of defrosting
during activation of the door microswitch input, the maximum temperature alarm is absent, provided the alarm was signaled after the activation of the input
parameters F13 and F14 have effect when the compressor is off
parameters F13 and F14 have effect when the compressor is on
if parameter P3 is set at 0, the device will function as if parameter F0 were set at 2
parameters F13 and F14 have effect when the evaporator temperature is below the temperature established with parameter F1
parameters F13 and F14 have effect when the compressor is on and the temperature of the evaporator is below the temperature established with parameter F1
the parameter can be changed also by implementing the procedure described in paragraph “Setting the configuration parameters”
if parameter P4 is set at 0, 2, 3 or 4, the condenser fan will function in parallel with the compressor
a compressor will be switched on when the room temperature or CPT temperature is above the "working set-point + r0/2" and another when the temperature is above the "working
set-point + r0"
a compressor will be switched off when the room temperature or CPT temperature falls below the "working set-point + r0/2" and another when the temperature is below the
working set-point
a compressor will be switched on when the room temperature or CPT temperature is above the working set-point and another when the temperature is above the "working set-point
