C-PRO NANO HPR0 APPLICATION MANUAL 3 User Interface 3.1 Display and keyboard The following interface is envisioned for the application: ⋅ A 4 display interface with 7 Built-In segments with icons ⋅ With 4 keys with navigation/editing the pages and they differ for display The following icons are also used: - Summer icon: identifies the cooling functioning mode (summer - chiller): if the heat regulation requests, it is on in fixed mode, otherwise it is off.
C-PRO NANO HPR0 APPLICATION MANUAL 3.2 List of pages This paragraph presents the main pages and menus found in the application. As shown previously, the main menu is divided into 3 levels: user, maintenance - installer and manufacturer.
C-PRO NANO HPR0 APPLICATION MANUAL 3.5 Main ON page The main page displays the temperature of the outlet water and the relative icons on at that moment. By pressing the DOWN key for about 2 seconds from this page, enter MENU. From MENU, by pressing the ESC key, go back to the main page. 3.6 Main Menu The main menu does not have a level and is the access point for all other system menus.
C-PRO NANO HPR0 APPLICATION MANUAL 3.9 Maintenance technician - Installer menu The maintenance technician - installer level password or higher must be entered in order to display/modify the parameters present in this branch.
C-PRO NANO HPR0 APPLICATION MANUAL 3.11 Project and Firmware Versions Press the UP+DOWN keys at the same time for about 2 seconds and successively press ENTER on the InFo label. The information regarding the versions of the project and the controller firmware are displayed in sequence, precisely: Project Number <-> Project Version <-> Project Revision <-> Firmware Number <-> Firmware Version <-> Firmware Revision Use the UP and DOWN keys to scroll the information.
C-PRO NANO HPR0 APPLICATION MANUAL 4 List of Parameters The same parameters organisation used for c-pro CHILL can be maintained. For the parameters and functions of the c-pro HPR0 application, see the following table. As an example, the codes used with CHIL have been maintained (that will appear on the LED display), but which will be “re-organised” regarding numbering depending on this new application.

C-PRO NANO HPR0 APPLICATION MANUAL HARDWARE CONFIGURATION Those eventually necessary (to be defined in the design phase) 5 Controls and regulations 5.1 Machine state The unit is switched-on/off using the relative On/Off key : Switch-on - press the relative key for 2 seconds: if all of the other conditions enabled are present, the machine goes to “ON”. Switch-off - press the relative key for 2 seconds: the machine goes to “OFF” mode.
C-PRO NANO HPR0 APPLICATION MANUAL 5.3 Regulation and management of the compressors The controller can manage up to a maximum of 2 compressors. Digital outputs for switch-on/off and protection inputs (pressure switches) are associated with every compressor. Switch-on/off is defined depending on the set/outlet temperature, some timing and request of the room thermostat and the indoor thermostat. The compressor switch-on control takes place on the basis of the outlet temperature AI1.
C-PRO NANO HPR0 APPLICATION MANUAL 5.4 Compressors status The compressor has one functioning state associated, which can be seen via the relative LED or in the states mask from the main menu. The compressor assumes the following states: - On: “On” appears on the state mask Switch-on stand-by: the compressor is in stand-by due to the switch-on protection times.
C-PRO NANO HPR0 APPLICATION MANUAL 5.7 Management of the geothermic circulation pumps and heating/cooling The application can manage the unit and system pumps. A safety digital input and a digital output for switch-on/off can be associated at every use. 5.8 Pump status The pumps are each controlled by a dedicated digital output (see I/O table). Functioning takes place on call of the ON-OFF thermostats (EXT and/or INT) and/or outlet temperature.
C-PRO NANO HPR0 APPLICATION MANUAL 5.10 Flow switches management The 2 unit flow switches are managed separately: heating/air conditioning circuit, geothermic circuit, but the setting of the “Flow switches alarm delay” is unique for the two flow switches. On expiry of the Flow switches alarm delay time, if the contact signals no flow, the alarm is given immediately, stopping the pump and preventing compressor switch-on.
C-PRO NANO HPR0 APPLICATION MANUAL 6 Programming The instrument can be programmed from front key or using the programming key. Programming key It is possible to save the value of all system parameters in the programming key and allow copying into one or more compatible instruments. The saving or reset operation can only be performed with machine OFF, by connecting the key to the programming container.
C-PRO NANO HPR0 APPLICATION MANUAL 7 Alarms All alarms are envisioned with manual reset from controller front key. In the event of an alarm: ⋅ The alarm icon starts to flash By pressing the ENTER key from the “Alar” menu, the code of the first active alarm is displayed. Once the conditions that caused the alarm in the unit have been eliminated, the alarm can be reset manually. To perform this operation: ⋅ be positioned on the page of the alarm to be reset ⋅ hold the ENTER key down for about 2 seconds.
