C-PRO MICRO SAVE APPLICATION MANUAL 6 REGULATIONS 6.1 State of the unit There are several unit switch-on/off procedures: 1) Via the relevant ON/OFF key Switch-ON: press the relevant key for about 2 seconds, if all the conditions are fulfilled the unit starts working (“ON” mode). Switch-OFF: press the relevant key for about 2 seconds, the unit stops working (“OFF” mode).
C-PRO MICRO SAVE APPLICATION MANUAL 6.1.1 OFF state for alarm When the machine is active and an heavy alarm occurs the unit switches into the OFF due to alarm status. In this case the unit and all devices are switched OFF and the dampers are completely closed until the alarm condition has been reset. When the unit is OFF for alarm it is possible to switch to the other OFF states by means of the relevant digital input, key or supervisor.
C-PRO MICRO SAVE APPLICATION MANUAL Set the PH99 parameter to “YES”(1) and wait until it becomes “NO”(0) again on the display. The system automatically restores all parameters’ default values. Note: After this operation switch OFF and back ON power supply to the board to prevent for malfunctioning. 6.
C-PRO MICRO SAVE APPLICATION MANUAL 6.6 Functionality of the COMPACT control solution This control solution offers the base functionality present also in the "complete" solution. 6.6.1 Supply and return fans The program manages two fans, supply and return, independently with a 3 steps control logic. This can be achieved using 3 digital output or one analogue output to pilot a speed variator with 3 speed levels.
C-PRO MICRO SAVE APPLICATION MANUAL 6.6.1.5 Fans status Each of the two fans can be in the following working states: 1. OFF: the fan is OFF. 2. ON V1: the fan is ON at speed 1. 3. ON V2: the fan is ON at speed 2. 4. ON V3: the fan is ON at speed 3. 5. Switch-ON stand-by: the fan is to be switched-on. Timing is in progress, e.g. stand-by due to pre-start of the outside air damper. The status shows the switch-on stand-by for each of the individual speeds. 6.
C-PRO MICRO SAVE APPLICATION MANUAL If the temperature T is between Tg and Tg + Tdiff (default 3°C, can be modified by parameter PF08) the current speed is maintained. Only when the temperature T becomes T ≥ Tg + Tdiff the fan speed returns to the normal condition (i.e. at the speed set by the user). 6.6.2.
C-PRO MICRO SAVE APPLICATION MANUAL 6.6.3.1 Cyclical defrosting with minimum temperatures The set point must be determined along with its differential for the activation of the defrosting cycle. Pr01: Setpoint ON OFF T. Anti-freeze Pr02: Diff.
C-PRO MICRO SAVE APPLICATION MANUAL 6.7 Features of the COMPLETE control solution Al functions of the COMPACT version are included in this version. Below are listed only the additional features of the COMPLETE control solution. 6.7.1 Post-Ventilation By setting the parameter PG05=1 it is possible to decide whether to run the fans for a time configured on parameter PF11, also after unit switch-OFF. If the function is active when the unit stops the fans keep working for further PF11 seconds. 6.7.
C-PRO MICRO SAVE APPLICATION MANUAL 6.7.3 Fresh air intake damper It is possible to manage an optional motorised damper (can be enabled by parameter PG04=1) for fresh air intake purpose. The damper is managed via ON/OFF (digital) activation. The damper can be either fully open or fully closed, modulation is not possible as well as a minimum opening. When the fans are requested to start first the damper is opened and, after a delay configured on parameter PS01, the fans are activated too.
C-PRO MICRO SAVE APPLICATION MANUAL Anti-freeze safety on hot water circuit (AL04) The anti-freeze mechanical thermostat (digital input DI7) is mounted downstream the coil either inside or outside the pipe.
C-PRO MICRO SAVE APPLICATION MANUAL 6.7.4.4 Heaters over temperature protection with automatic reset By setting the parameter PA16=1(high temperature) it is possible to decide whether to use the supply high temperature alarms or not.
C-PRO MICRO SAVE APPLICATION MANUAL 7 DIAGNOSTICS The application can manage a series of alarms relevant to the fans and the devices configured. Depending on the various types of alarm it is possible to configure a manual or automatic reset, a possible delay and the actions to carry out in the specific case. When one or more alarms are active the alarm icon on the main page flashes, if configured (PH20=1) and only with the machine ON the buzzer is also activated.
C-PRO MICRO SAVE APPLICATION MANUAL 7.2 Alarms table Below is a list of all alarms managed by the application. The order of presentation is the same as the order of active alarms occurrence. The alarms can be displayed also with the machine in OFF status.
C-PRO MICRO SAVE APPLICATION MANUAL 7.4 Alarms log The controller record the ALARMS LOG in a non-volatile area of the memory organised as FIFO (First In First Out), that is a list of the last 100 alarms occurred. To display the alarms log, select LOG from the General menu or press ESC from the main page to display this page: Move the cursor on “Show HISTORIAN>>>” and push the Enter key.
C-PRO MICRO SAVE APPLICATION MANUAL 8 MODBUS VARIABLES The controller can be managed by a supervisor via Modbus protocol. The communication takes place via optional TTL/RS485 serial interface outside the controller.
