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

Regulation set point

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: Start

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

Parameters

SetUp:

Parameter: y01, y03, y07,Cid

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

Buzzer and relay

Parameter: BUZ, Adl, AOF

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

Parameter: Cid, Ser, bAU, COM

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;
	The level of access is highlighted in the yellow square;

Unit Configuration

Parameter: H06, H40, HEA

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

Temperature Control

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;
