3. GENERAL DESCRIPTION
This card provides the s top-rising cell control. Some automatic program s, a manual program and a cell pre-cooling
cycle are available.
Each automatic program consists of five phases: stop rising, preservation, awakening, rising and slowing down.
The manual program consists of three phases: cooling, heating and climatization.
4. POWER SUPPLY
When the ca rd is on, the s tring “ EVCO s .r .l.” will be shown for eight s ec onds , and then the car d will go in the Off mode,
in stand-by or in a cycle mode, depending on the mode it was in when it was switched off.
The string “EVCO s.r.l.” can be replaced with a neutral string: simply set up parameter P1 = zero.
5. OFF
If the card is on Off mode, the LCD display will show the following string:
Press the ON-STANDBY key to switch the card on.
Press the MENU key to view the firmware ID for three seconds.
Regardless from the mode the card is in, by keeping the ON-STANDBY key pressed for thr ee seconds the card will
return to the Off mode.
OFF_
6. SWITCHING ON
Current date and time will be shown on the display when the card is in standby mode.
The card status after a blackout depends on param eter P10 for the automatic param eters and parameter P12 in the
case of manual programs.
The meaning of the parameter is:
P10 = 0 (P12=0): the current cycle will only resume if the duration of the blackout in question was shorter than the
value set up by way of parameter P9 (P11), otherwise the card will go in standby mode.
P10 = 1 (P12 =1): the current cycle will always start again after a blackout.

17. STEAM GENERATOR
There is an output available to activate a steam generator. T his output will be switched on for every phase requiring
the humidification phase, apart from any P32 parameter value (selection of the humidification mode).
If parameter P72 has value 0, opening the door will result in no ef fe ct; if par am eter P72 has value 1, when the door
is opened the steam generator will be switched off.
If you are using a pot inside the cell, it is advisable not to connect this output and to control the pot through the
humidifier output.
18. HUMIDIFICATION
Opening the door will immediately switch off the Humidification output.
There are three control m odes for cell hum idity generation and control, which can be selected by setting parameter
P32 (see the following paragraphs).
18.1. Humidification without humidity probe
By setting P32 = 1 or 2, the humidity probe will be enabled and the humidification control will occur as follows.
P32 = 1 A time control without the probe will occur. Two parameters are used, P34 and P35. Parameter P34
establishes the complete duration of the humidifier on/off cycle while P35 defines the duration of the
humidifier activation cycle when a humidity percentage equal to 100% has been set.
Example:
P34 = 60 seconds and P35 = 50 seconds, setup percentage = 60%
The humidifier is ac tive for 30 sec onds (60% of param eter P35) and then stays off for 30 s econds (P34-
60% of P35). The cycle then starts again.
% P35
P34
Inizio fase
Humidity injection is interrupted if the tem perature in the cell is lower than the value determined by parameter P31 for
both the manual and automatic cycles.
P32 = 2 A time control for a maximum of 10 minutes will occur. During the program setting, you will have to
choose a number between 0 and 10, meaning the m inutes of humidif ication. Parameter P33 determ ines
the pause between two humidifier-on cycles. The hum idif ier will rem ain on for the preset tim e and then go
stay off for the pause period (param eter P33). The cycle will then start again. If the pause time is 0, the
humidifier will always remain on, regardless of the preset time.

This function is always active during the awakening, ris ing and slowing down phases, but it can also be enabled for the
stop and preservation phases by way of parameter P36.
Regarding the manual cycle, the humidification is only active during the heating and climatization phase.
In case the temperature in the cell is lower than parameter P31, the humidification function will be disabled.
If you are using a pot in the cell, the humidifier control time must be set in minutes and parameter P41 must be = 1.

19. DEHUMIDIFICATION
This function is always active when the humidity probe is enabled. By setting parameter P32 = zero, the humidity probe
will be enabled. Dehumidification occurs by using the solenoid valve and the compressor switching on or by setting

The solenoid valve is switched on for a per iod of time determined by parameter P44. If within this time the humidity
probe drops below the setpoint + dead zone value, the solenoid valve will switch off and the com press or will switch on for
the ‘on’ enforced time determined by parameter P29.
If the probe drops below the setpoint + dead zone value before time P44 is over, the solenoid valve will switch off and
the compressor will switch on for the period of time determined by parameter P29.
If parameter P71 is set at 1 (output K3 does not manage the s olenoid valve, only the light in the cell), dehumidific ation
will only require the compressor, which will be activated P44 seconds after the dehumidification request.

zmc is the hot dead zone for the ongoing phase
istc is the hot adjustment hysteresis (parameter P21)
Never switch on resistances during the stop and preservation phases of an automatic cycle or during the refrigeration
phase of a manual cycle. Resistances must be switched on for a minimum time, determined by parameter P30.
During the awakening and rising phases, the temper ature inc reas e is adj usted by dividing the temper ature ar ea by n steps
(which are preset by means of param eter s P24 and P25) s o that the heating will be gradual according to setpoints that are
close to the desired value, as follows:
If the temper ature in the cell is 5°C at the awakening start, the setpoint that has been preset for the awakening phas e is
25°C, the number of steps is 4 and the duration of the phase is 40 m inutes; resistances work for 10 m inutes at the 10°C
temperature setpoint, for 10 m inutes at the 15°C temperature setpoint, for 10 m inutes at the 20°C temperature setpoint
and for the last 10 minutes at the 25°C temperature setpoint.
Stop leavening specific ations
CT1SA0040101
Vers. 1.11 23/36
Compressor ac tivation may be enforced at the beginning of the awakening and rising phases ; the duration of such
enforced activation is determined by parameter P29.
Compressor activation is subject to the safety times (parameters P26, P27 and P28)
21. SOLENOID VALVE
Only present if P71 = 0. When P71 = 0, P44 must be configured correctly.
The solenoid output is always activated together with the compressor, except for when compressor activation is
enforced, which happens at the beginning of the awakening and rising phases (the solenoid will remain disabled). The
solenoid is also used whenever the cell requires dehumidification (see paragraph 19).
22. LIGHTS
The light output (present if param eter P71 has value 1) will be switched on when you open the door and switched off
when you close the door.
23. EVAPORATOR FAN CONTROL
You can choose the fan control output from one of the relay outputs and a phase cut output. This is done by means of
parameter P45. If P45 = 0, fan c ontrol will be perform ed by output LOAD5. In this case, you can also establis h whether is
subject to the activation of the compressor and/or the resistances or if they must always remain on. If P45 = 1, a
proportional adjustment through the phase cut will be chosen.
23.1. Relay output control (P45 = 0)
If you select the control simultaneous mode, fans will be activated at the same time as the compressor and/or
resistances, but will be switched off with a delay determined by parameter P54. During the pauses, in case of
simultaneous operation, fans will be cyclically switched on according to the value of two parameters (P55 and P56).
Example of simultaneous operation subject to the compressor.

If parameters P55 e/or P56 are = zero, fans will remain off.
Pause/working time will always be reset when a cycle is started.

Where:
Setpoint is the preset adjustment setpoint for the ongoing phase

Based on the temperature in the cell regarding the setpoint, fans will be kept at the maximum speed or will be
proportionally adjusted according to the difference between the cell temperature and the setpoint.
The minimum speed (equal for all phases) is configurable by the parameter P57.
The maximum speed is c onf igur able f or eac h phase ( f or manual or automatic cycle) by the parameters P79, P80, P81,
P82, P83, P84, P85, P86.
If a dehumidification cycle starts during the fan proportional adjustment, the minimum speed will no longer be
determined by parameter P57 but by parameter P59 and the fans will remain on even if the door is opened.
24. DEFROST
Defrost is active only during the stop and preservation phases of the automatic cycle and during the refrigeration phase
of the manual cycle. It can also be switched on by selecting its own menu. Both the automatic and the manual defrost will
only occur if the evaporator probe temperature is lower than parameter P60.
The defrost mode is subject to parameter P73:
If parameter P73 = 0, during the defrost output K2 will be switched on.
If parameter P73 = 1, during the defrost both output K1 and output K2 will be switched on.
Fans are activated according to the value of parameter P64.
The defrost cycle, if automatic, is repeated regularly (parameter P61), and each defrost cycle may finish as follows:
• as soon as the parameter P62 time elapses
Stop leavening specific ations
CT1SA0040101
Vers. 1.11 25/36
• alternatively, when the evaporator probe is higher than parameter P60.
All defrost cycles will be interrupted when passing from the preservation phase to the awakening phase of an automatic
cycle.
At the end of the defrost cycle, you must wait for the end of the dripping tim e (parameter P63) before switching the
compressor on, and for the end of the fan stop time (parameter P63+P64) before switching the fans on.
Regarding compressor activation, safety time (parameters P26, P27 and P28) is still the priority.
Opening the door will not stop the compressor, but will cause the fans to go off, regardless of P64.
25. SIGNALS AND ALARMS
Both visual and acoustic signals will be given in case of malfunction. Below is the complete list of alarms/signals.
