  • Page 3 VISUALIZATION MAIN SCREEN The touch screen control panel has been designed to manage units of Mechanically Controlled Ventilation with Heat Recovery (VMC-RC) in a simple and intuitive way. The user manages the control by means of the icons of the graphic screen making a slight pressure on them; The direction buttons, which appear after the pressure in a modifiable parameter, allow the user to interact with the unit by going through menu items and modifying values.
  • Page 4 MANAGEMENT OF FAN SPEED, FLOW OR CONSTANT PRESSURE To modify this parameter, the icon at the top right of the synoptic table must be selected by clicking on it (it will turn green and the direction buttons will appear). Then press the icon of the address button up to increase or down direction to decrease the value located next to it; Once the desired one is located, press the OK button to confirm the selection.

  • Page 5: Booster Function

    BOOSTER FUNCTION By selecting the icon on the lower left you access the booster function. Through this you can select a time interval (from a minimum of 1 mi- nute to a maximum of 4 hours) in which to operate the unit at maximum power. The booster function is a priority with respect to other modes of fan speed management.

  • Page 6: Menu Selection

    PREHEATING MANAGEMENT In addition to the post-heating, the CTRL-MAX control is able to manage an electric preheating system (operated by a PWM signal or on-off ) to prevent the formation of ice inside the heat exchanger. The control automatically activates the anti-frost procedure when the temperature measured by the expulsion probe (Tx) drops below the value of 3 °C.
  • Page 7 STATUS MENU: OPERATING STATUS If the remote control panel is used to manage several units (master-slave mode), a screen with the list of available machines (max 4) will appear in the menu: Selection of unit to control configuration menu status Display menu status To view the status of an individual unit, select it (move with the arrows and confirm the selection with OK).

  • Page 12 Disabled heating Post-heating enabled After carrying out the personalization of a day of the week according to your own needs (for example, Monday), you can copy the program- ming made on another day without having to repeat the whole procedure described above. In the summary display window of time slots, select the day in which you want to copy the previously made programming (for example, Tuesday) and press OK.

Press the OK button to confirm the selection, the day will change from green to blue.

  • Page 14: Alarm List

    ALARM LIST Parameter State The configuration is correct. The configuration of the digital inputs or hardware is incorrect. Check the ext. Configuration Inputs in the factory menu. (eg if the same function is configured for several inputs) or Hardware (Hw evo-compact-> el.water). Communication The communication between the cards in the machine and the remote control panel works correctly.
  • Page 15 It is present only if the air after-treatment management is configured with wa- ter coil (Factory menu). The temperature of the water leaving the coil is higher than a safety threshold; there is no risk of freezing the water in the coil. Tw (water low) Risk of freezing the liquid in the water coil.
  • Page 16 It is only present if the automatic speed management of the fans with CO or CO-VOC sensor (Installer menu) is configured or there is an excess of CO2 in the Autominutes environment. The sensor works correctly. Possible anomaly in the sensor. It is activated if the unit fails to exit the antifreeze mode of the exchanger within 2 minutes.
  • Page 17 Bypass configured in universal mode (Factory menu), three values can be selected for the bypass parameter: Automatic bypass: A temperature range, comprised between TMIN and TMAX, is considered comfortable for the user; If the internal temperature (Tr) is within this range, the bypass will remain closed.

  • Page 19 HR Sensor The speed of the fans will be regulated by a relative humidity (RH) sensor with 0-10V output and linear characteristic between 0 and 100% RH (0V correspond to 0% RH and 10V correspond to 100% RH); If the external signal from the HR sensor assumes a value equal to 0V, the control will signal an alarm.
  • Page 20 AutoMin % This parameter is available only if the auto parameter is set to ext. or HR sensor. It can take values between 0 and 99% (steps 1%) with the limitation that AutoMin% <AutoMax% For units equipped with variable speed fans: If auto signal ext.
  • Page 21 AutoMinutes 000 -> 240 This parameter is available only if the auto parameter is set to a value other than none. No (default value) there is no effect on the operation of the system. It is a value expressed in minutes, it represents the interval of time elapsed since the signal of the external device for the auto mode has reached, or exceeded, the value AutoMax% or Auto Max ppm, without descending below said value, above which indicates an anomaly in the external device (CO2 probe, HR or external signal).
  • Page 22 Vel.max 055% ->100% This parameter is available if the control is set to manage variable speed fans (Factory menu) Default value 100%, is the maximum speed of the fans expressed as a percentage of the nominal value (reduction of the maximum speed). The maximum speed adjustable in the main window will always be 100% even for Vel values.
  • Page 23 Caud.Extr.=XXX% Caud.Ingr. 067%->150% This parameter is available only for units adjusted to constant pressure with control over the two flows. Default value 100%, expresses, in percentage, the desired ratio between the flow rate of the extraction fan and the supply fan, allowing an imbalance to be made between the flow rates of the two flows.
  • Page 24 WINTER TEMPERATURE / SUMMER TEMPERATURE Through these parameters you can access the menus below to adjust the effective return temperature threshold values (Tr) for bypass or base management for bypass management with air after-treatment. The summer / winter values coincide in order to have an optimal setting for all seasons.
