1 INTRODUCTION
c-pro 3 micro CHIL | Application manual ver. 1.0 | Codice 144CP3CHE104
1.1 Introduction
The programmable controllers of the c-pro 3 micro CHILseries are devices studied for the management of singleandtwo-circuits
chillers-heat pumps up to three scrollcompressors for each circuit.
They make use of the programmable controllers, of the I/Oexpansions and of the remote user interfaces belonging tothe c-pro 3 series
and are programmed with an applicationsoftware implemented with the development environmentUNI-PRO 3.
They are available in built-in and in blind version; the blindversions must be used with a remote user interface.
The controllers can manage air to water and water to waterchillers-heat pumps; through the CAN communication portthe controllers
can also communicate with an externaldriver (EVDRIVE03) for bipolar stepper electronic expansionvalves.
They can be powered in alternating current (12 VAC). Through the programming port it is possible to make the upload and the
download of the configuration parameters (using a common USB peripheral); through the RS-485 one, with MODBUS communication
protocol, it is possible to connect the devices to the set-up software system Parameters Manager or to the plants monitoring and
supervision one via Internet CloudEvolution instead. Through the CAN communication port it is finally possible to connect the devices to
the I/O expansion, to the remote user interface and to the external electronic expansion valves driver.
The application program is capable of managing air-to-water and water-to-water units, mono or twin circuit.
The following are only some of the numerous control functions available:
Manage up to 3 scroll compressors for each circuit
Manage compressors with cooling – heating mode
Manage fans with phase-cut module
Manage electronic valve EVDRIVE03 for each circuit
Free-Cooling management
Defrost and anti-frost
Double set-point that can be enabled from external contact
Dynamic set point compensation
Pump-down management
Build in schedule with 2 daily programs
Control of condensing pressure / linear or stepped evaporation
One, two or no circulating pumps
One, two or no source circulating pumps

5 USER INTERFACE
For the application, two types of interface are provided:
• Built-in LED-display interface
• Remote LCD-display interface Vgraph.
Both interfaces feature 6 keys for navigation/page editing, and differ in their display mode of certain associated statuses, i.e. via icons.
For both versions, a description is provided of the keys used by the application; indeed, according to the interface in use, it is possible
to manage a different number of keys.
5.1 Displays and Keyboards
The keyboard features 6 page navigation and value editing keys, which have the following functions:
Symbol
Functions
In editing, it modifies parameters; otherwise, it moves the cursor.
During editing, it confirms the value; otherwise, it sends any commands associated to the text where the
cursor is positioned.If pressed down and held for about 2 seconds, the ENTER key enables access to the main menu.
If held down during display of an alarm page, this key enables resetting of the alarm.If alarm pages are being
displayed, every key press scrolls all active alarms.
During editing, it cancels the value; otherwise, it requests any default page that might e associated with the current
page.If pressed down and held for about 2 seconds, the ESC key enables ON/OFF switching of the machine.
If pressed in the main page, this key will display the list of all active alarms.
It displays the pages of the same level in succession.

6.1 Password
Each menu is assigned a level, which affects the accessibility of the various menus.
Each level is assigned a password, which enables access to the various functions featured in that menu; once the correct password has
been entered, protected functions become accessible. Entering of the correct password has two consequences:
• Unlocking of the related level;
• Unlocking of its sublevels.
All level passwords can be modified from the same level or from higher levels. For example, from the constructor level it will be possible
to modify all passwords of underlying levels, by using the appropriate page.
The range of values that can be set for a password is -999 / 9999.
After 4 minutes have elapsed without any key being pressed, the password expires and it is necessary to reset it.
6.2 Unit OFF main page
The main display page varies according to the machine status, i.e. on or off:If the machine is switched OFF, Unit OFF is displayed, with
indication of the cause for the shutdown (keyboard, DI, Supervisor, Scheduler, Alarm, Change-Over).
Pressing the ESC key from this page brings the user to the Alarm page.

6.3 Unit ON main page
When the unit is turned on, the following main screen will be displayed:
At the bottom of the page, icons will be displayed that indicate various statuses of circuit operation.
The table below contains graphic representations of the individual icons, the relative operational status and what is being verified.
From left to right:

defrost, circuit status, RTC and all configured sensors. In case of fault status of the sensors, the value field of the corresponding sensor
displays “----“, or else “----“ if the sensor is disabled.
Pressing the ESC key from this page brings the user to the Alarm page.
In case there is an active alarm, the alarm icon will be displayed alternatively with
the icon of the operational mode (summer/winter)
Indicates that circuit defrost is in progress (1,2).
If flashing, it is in dripping phase
Indicates that the antifreeze resistance mechanism is active (heat sink or source)
in the circuit indicated (1,2 1+2)

• Compressor 2. If on, it means that at least one compressor of circuit 2 is active; if off, it means that no circuit compressors
are active; if on and flashing slowly, it means that a circuit compressor is in the alarm state; if on and flashing quickly, it
means that a circuit compressor is in manual mode.
• Pump. If on, it means that a heat sink pump is active; if off, it means that no pumps are active; if on and flashing slowly, it
means that a pump is in the alarm state; if on and flashing quickly, it means that a pump is in manual mode.
