About
The user interface has been developed for LCD displays.
Note: playing with MCXShape, it is very easy to customize the structure and the visibility of the menu: so the following indication cannot match with all the compiled software
Main screen
Keyboard
: Scroll UP, increase a value
: 3s when in main screen: toggle ON/OFF
: Scroll down, decrease a value
: 3s when in main screen: toggle Heat/Cool mode
: exit and save,
: when in main screen: access the active alarm list
: 3s when in Alarm screen: manual reset
The LEFT and RIGHT keys, if present, allow you to move the cursor to the desired option

Menu Screen: Status |
|
|
|
|
|
Menu: Alarm |
Each alarm is described through an alarm description (for LCD display only), an alarm code and |
|
|
the time since its activation in the format hours:minutes:seconds (seconds for LCD display only). |
|
|
Note: You can also access alarm visualization by pressing the ESC key from the main screen. |
|
|
The alarm is only reset if the alarm has ended and it will return you to the main screen. |
|
|
Note: Alarms can also be reset by pressing ESC for 3 seconds on the alarm screens |
|
|
|
|
Menu: Login |
Parameters and Menu are organized into 4 access levels. Levels from 1 to 3 are linked to a password. |
|
|
Elements cannot be accessed when they are on a higher level than the entry level. The level of each |
|
|
parameter and menu is defined with MCXShape |
|
|
• |
Level 0 is accessible without password |
|
• |
Levels 1-3 are linked to a password (Check parameters L01, L02 and L03) |
|
• |
Level 4 is not linked to a password, which can be used to make a menu or parameters |
|
|
never accessible. |
|
You can log in from the menu: |
|
|
if the password provided is not correct you remain on the login screen. Otherwise you return to the |
|
|
main menu. |

Menu: Parameter |
This menu contains all the parameters. |
|
The meanings of the parameters are explained in the last part of this manual |
|
|
Menu: I/O Display |
Display input and output values |
|
You have access to three screens showing all the input and output values; each screen shows a group |
|
of 8 I/Os. Use UP and DOWN keys to scroll. |
|
The second and third screens are used with MCX15 and MCX20 only. |
|
The example below shows the first screen. |
Menu: I/O Config |
From the menu I/0 Config it is possible to change the position of all the inputs and outputs used |
|
in the software |
Note: “CAL”is the offset to add of the reading, the other items are the ones available in the MCXShape

How to switch ON-OFF and change the application mode from the parameters.
y01- System ON/OFF |
O=OFF |
|
1=ON |
|
Together with the digital input ON_On/Off the parameter y01 defines whether the machine is in the |
|
ON or OFF state |
|
The parameter y01 can be also changed from the menu/Start, by Modbus or CANBUS and from the |
|
start screen by holding the up-arrow key. |
|
Below the logic that manages the ON-OFF status, the ON status is always delayed by 3 seconds from |
|
the power ON |
|
|
y03- System heat/cool |
O=Cool |
|
1=Heat |
|
Together with the digital input DHC_Heat/Cool, the parameter y03 defines whether the machine is in |
|
Cool or Heat mode: |
|
The digital input DHC_Heat/Cool is without predefined meaning, each time that it’ s switched, the |
|
parameter y03 is automatically changed. |
|
Note: It works for H40<> 0 |
|
|
y07- Restore default |
0=No means no action |
parameters |
1=Yes means that the default parameters (the ones used in the MCXShape) are loaded |
|
Note: after the restore parameters process, the parameter y07 will be reset to zero |
|
|
Cid – Serial address (CAN) |
It defines the ID in the CANBUS communication |
|
Note: the baud rate and the settings of the CANBUS communication are tuned through the bios |
|
menu or through the MYK |
|

How to set it up.
BUZ- Buzzer activation time |
It is in minutes. It defines the maximum time that the buzzer can work; |
number |
BUZ=15 means that there is no limit to the active time of buzzer |
|
|
Adl- Alarm relay activation |
It is in seconds. It defines the delay of the alarm relay when there is an alarm |
delay |
|
|
|
AOF- Alarm relay active if unit |
It defines whether the alarm relay works in OFF state of the chiller |
in off |
|
|
|
Serial setting |
|
How to configure the communication port.
SEr – Serial address (Modbus) |
Defines the ID in the Modbus communication |
|
|
bAU – Serial baud rate |
Defines the baud rate in the Modbus communication |
(Modbus) |
0 means Reserved: do not use |
|
1 means 1200 bits/sec |
|
2 means 4200 bits/sec |
|
3 means 4800 bits/sec |
|
4 means 9600 bits/sec |
|
5 means 14400 bits/sec |
|
6 means 19200 bits/sec |
|
5 means 28800 bits/sec |
|
8 means 38400 bits/sec |
|
9 means 57600 bits/sec |
|
8 means 115200 bits/sec |
|
|
COM – Serial settings |
Defines the serial settings of the Modbus communication |
(Modbus) |
0 means 8N1 |
|
1 means 8E2 |
|
2 means 8N2 |
|
|
Password |
|
Parameter: L01, L02, L03 |
|
How to change the password |
|
|
|
L01, L02, L03- |
Typing the parameter L0x, in the login screen, you will be able to see all the parameters and menu |
Level x password |
with level <= of X; |

General setting of the fridge circuit
Digital input: C11, C21
Digital output: C11, C21, HC1, HEA
Analogue output: CI1
H06 – Number of compressors |
It defines the number of compressors in the circuit; |
per circuit |
|
|
Note: the software manages only one circuit |
|
|
H40 – Heat pump type |
0=No means that the software doesn’t perform the heating mode |
|
1=GAS means that the software performs the heating mode, the internal coil acts as evaporator in |
|
cooling mode and condenser in heating mode |
|
1=H2O means that the software performs the heating mode, the coils keep the same function in |
|
both heating and cooling mode |
|
Note: one digital output “HC1_Reverse Valve C1” is reserved for controlling the reverse flow valve |
|
|
HEA – Enable Heater |
0=No means that the heater is not used |
|
1=Heat the heater is managed by parameters HE1 end HE2 |
|
2=Defrost the heater works only during defrost and is managed by parameters HE3 end HE4 |
|
3=Both the heater works like HEA=1 and HEA=2 |

Parameter: rEG, rET, Sc1, rC1, SH1, rH1, SdC, SdH, Rin,
SOE, SOO
Digital input: SE2
Analogue input: Tin, TOE, SOV
rEG – Analogue input for |
0= Tin : reference sensor is Tin_Tin Evaporator |
temperature regulation |
1= TOUT : reference sensor is TOE_Tout Evaporator |
|
|
rET – Regulation Type |
It defines the relation between the temperature gap and the power request to the circuits. |
|
0=P : Power request to the circuits increases proportionally with the regulation error, it is 100% when |
|
the regulation error (the gap between set point and the reference sensor ) is equal to rC1 (rH1) |
|
1=PI : the power request is the sum of P regulation (rET=0) more a component (Integral part) that |
|
increases time by time in relation to the regulation error; the speed of the Integral part depends on |
|
the parameter Rin. |
|
In the PI regulation the balance is reached only when the regulation sensor gets to the set point. |
|
|
SC1- Cooling temperature |
It defines the set point in cooling mode |
set point |
|
|
|
rC1- Cooling temperature |
See parameter rET |
differential. |
|
|
|
SH1- heating temperature set |
It defines the set point in heating mode |
point |
|
|
|
rH1- Heating temperature |
See parameter rET |
differential. |
|
|
|
Rin- Ti |
It is the integral time of the PI regulation, the bigger the value of Rin slower is the action of the Integral |
|
part. |
|
See parameter rET |
|
|
SdC- Offset for set point in |
In economy status and cooling mode the regulation set point is shift of SdC. |
cooling |
|
|
Note: the digital input SE2_Second set point defines if use comfort set point (SC1 or SH1) or the |
|
economy set point (SC1+SdC or SH1-SdH); |
|
|
SdH- Offset for set point in |
In economy status and heating mode the regulation set point is shift of SdH. |
heating |
|
|
Note: the digital input SE2_Second set point defines whether the comfort set point (SC1 or SH1) |
|
or the economy set point (SC1+SdC or SH1-SdH) is used; |
